The Rise of Off-Grid Homeschooling

In today’s fast-paced and interconnected world, the idea of homeschooling off the grid may seem unconventional, even radical to some. Yet, as the possibilities of technology expand, so too does the desire of families to seek an alternative approach to education that emphasizes self-reliance, practical skills, and a deeper connection with nature. In this blog post, we will examine the benefits and potential drawbacks of homeschooling off grid, shedding light on this unique pathway to education.

Living off grid often sparks notions of surviving in remote wilderness, completely detached from society. While this can be the case for some families, it is more commonly associated with a conscious choice to minimize technological dependencies and prioritize a sustainable lifestyle. Off grid homeschooling encourages parents and children to forge a deep connection with nature, fostering an appreciation for the environment and instilling valuable life skills.

Why Families Are Choosing Homeschooling Away from the Grid

In recent years, an increasing number of families embracing the homesteading and prepping lifestyle have made the bold decision to withdraw their children from public schools and embark on the journey of homeschooling. According to the National Home Education Research Institute, approximately 2.5 million children in the United States were homeschooling in 2019. This exponential growth can be attributed to diverse reasons such as personal philosophies, dissatisfaction with the traditional education system, or the desire for a customized education to meet individual needs.

This transformation has also been driven by a range of factors, such as concerns about safety, curriculum limitations, and a desire for a more self-sufficient and resilient lifestyle. 

• Safety Concerns: One of the primary reasons families choose to homeschool their children within the context of homesteading and prepping is concern for their safety. This is driven by a combination of factors, including rising violence and bullying in schools, exposure to harmful influences, and the lack of control over their children’s well-being.
• Curriculum Limitations: Another factor prompting homesteading and prepper families to opt for homeschooling is the frustration with curriculum limitations in public schools. The standardized approach fails to cater to the unique needs and interests of children, hindering their holistic development. 
• Self-Sufficiency and Resilient Lifestyle: Homesteading and prepping families prioritize self-sufficiency and resilience as essential life skills in a rapidly changing world. By homeschooling their children, parents can instill values such as sustainability, self-reliance, and critical thinking that align with their lifestyle goals. Homeschooling complements the efforts of off grid or self-reliant parents in the raising of their children to be adaptable, resourceful, and prepared for any challenges they may face.
• Building Strong Family Bonds: Homeschooling allows families to spend more quality time together, fostering strong relationships and deepening the parent-child bond. Research suggests that close family ties positively impact a child’s emotional well-being, academic success, and overall development.

The Core Benefits of Off-Grid Education

• Personalized Learning: Off-grid homeschooling allows you to design an educational experience that ignites your child’s passion for learning, adapting to their unique learning styles and interests.
• Practical Life Skills: Beyond academics, children learn invaluable skills such as gardening, cooking, and resource management, essential for a self-sufficient life.
• Strengthened Family Bonds: This educational path brings families closer, creating a supportive and nurturing environment for growth.
• Environmental Awareness: Living and learning off the grid instill a profound respect for nature, teaching children the importance of conservation and sustainable living.
• Integrating Academics with Homesteading: Off-grid homeschooling seamlessly blends daily homesteading tasks with educational lessons, turning every chore into a learning opportunity. From math and science to history, the practical application of academic concepts has never been more engaging.
• Adapting to the Seasons: With off-grid homeschooling, the curriculum evolves with the seasons, offering diverse learning opportunities throughout the year. This dynamic approach ensures that education is always relevant and connected to the natural world.
• Creating a Vibrant Off-Grid Homeschool Community: Transitioning to off-grid homeschooling doesn’t mean going it alone. Building a community with other like-minded families can provide a supportive network, enriching your child’s educational experience through shared learning and collaboration.

Is Off-Grid Homeschooling Right for You?

The answer to that question is quite simple… YES! You need neither access to high-speed internet nor a whole room dedicated to homeschooling to offer a rich and inspiring learning experience for your children. A few shelves or storage tubs are all that is needed to house learning supplies in an organized manner.

Space for books somewhere in the house, storybooks, living books, history books, any kind of book your children are inspired by and want to sink their teeth into are worthy of a spot in even a limited space home. Borrowing books from the local library can be a great way to open up the joys and wonders of reading to your children when home space or the family budget will not allow the development of an extensive home library.

Reading books will not be a drain on your off-grid energy system – nor will it cause the brain drain far too many children who are addicted to video games or cellphones are sadly experiencing it on a global scale.

“Gameschooling” is another superb way to educate your children at home without taxing your off-grid energy system. You can purchase or make printable learning games for your children to use, but old-fashioned board and card games can be infused into your off the grid homeschool too. When playing any type of board games, the children are reading, comprehending, following directions, developing analytical skills, predicting, inferring, and quite often counting too!

If you’re contemplating an educational path that breaks free from conventional norms, off-grid homeschooling offers a compelling alternative. With its focus on personalized education, life skills, and a connection with nature, this approach could be the key to unlocking your child’s full potential. Don’t let your child miss out on this transformative experience—consider the path less traveled and embrace the wonders of off-grid homeschooling.

Vocational Skills and Academics

Off-grid living pairs superbly with teaching useful vocational skills and life skills – and even blending them in with academics! Not only can you successfully homeschool right at your kitchen table with multiple children, but you can (and should) also let the outdoors be your classroom. Sitting in a chair is neither necessary nor conducive to true learning. In addition to using the outdoors, nature, off-grid homesteading chores, and livestock husbandry as part of your child’s academic studies. You can actually use the off-grid home infrastructure as part of your weekly lesson plans.

Life skills learning opportunities abound in your off-grid home. Teaching your children how the water collection system or off-grid well pump works involves science, some math, and most definitely vocabulary comprehension. Learning about water works on your off-the-grid homestead can also be turned into a reading (plans, history, instruction, etc.) and writing lesson to detail how the system works, how to fix a problem, detailing a hand-drawn diagram, or how to expand the system. The child will be learning valuable life skills along with honing their academic abilities.

How Can The Portage Maine Boiler Be Used In My Off-Grid Homeschool?

Using tools, systems, and infrastructure provide functional learning that will enable your children to develop life-long useful skills. The outdoor boiler can be used as a homeschooling teaching tool in your off-grid homeschool. The Portage Main Boiler brings a science lab right into your own home. Children can also keep a log and track how much wood is used throughout each season, compare and contrast their findings, estimated, track, and compare how much wood is used versus heat output and temperature during a day and or week, track the time it takes to chop and split the wood needed to provide energy for the off-grid house, and estimate savings the family has enjoyed by not being connected to a conventional heat or energy source.

Conclusion

Homeschooling during the colder, off-grid winter months can challenge your creativity, but keeping your family warm with activities like insulating projects or studying the physics of heat can become both practical and educational. Just as the grid fades into the background, traditional school walls give way to the boundless classroom of nature. Your off-grid curriculum can adapt to integrate environmental science through tracking snowfall patterns, understanding animal adaptations, or even astronomy during the long, clear nights.

Living off-grid doesn’t mean compromising on education; it’s about enriching it with real-world experiences and survival skills that books can’t teach. Embrace the off-grid homeschooling journey as a profound way to connect with your children and the world around you, preparing them for a sustainable future in harmony with nature.

A. Refractory Brick Lining

The Portage & Main Ultimizer is a refractory lined, dry base boiler. In the industry it has become known as an “updraft gasifier” because of its efficient burn. The Ultimizer is simple to use, easy to maintain and not fussy about the fuel it burns. It is very important to understand the “fire triangle” in order to fully appreciate the advantages of the Ultimizer design, and how it will save you fuel, money and time. To achieve a clean, efficient burn with complete combustion, an optimal balance of OXYGEN, HEAT & FUEL is required. The Portage & Main Ultimizer has been specifically designed to achieve this optimal balance.

Dry base design, zero ash line corrosion & no bridging 
The heat stored in the refractory lining helps ensure that a more complete combustion process occurs. I.e. fuel is reduced to charcoal in a 3-stage process.

STAGE 1: The fuel is heated to evaporate and drive out moisture. This starts at 212 degrees F

STAGE 2: It starts to break down on a chemical level at 500 degrees F. Volatile matter is vaporized. These vapors contain 50% to 60% of the heat value of the fuel, making it imperative for them to be burnt properly at a temperature in the range 1100 degrees F for maximum combustion efficiency. When all the volatile gases have been released, the remaining material is charcoal

STAGE 3: Charcoal burns at temperatures in excess of 1100 degrees F. Latent heat also helps in the re-ignition of the fire at the start of the next burn cycle. It also helps to dissipate moisture that is a result of the combustion process. The dry base boiler design gives a very hot burn. The water jacket sits above the brick line so it isn’t up against the fire, taking away the heat prematurely. This eliminates ash line corrosion and the fuel is completely burnt, resulting in considerably less ash.

B. Air from above & below

Exhaust gases make their 1st and 2nd pass at the top of the firebox where they move under and around a water-cooled baffle and into the heat exchanger. Gases then travel to the front of the boiler in a 3rd pass, make a 180 degree turn and move in a 4th pass to the back of the heat exchanger. In this way, all available heat is taken from exhaust gases before they exit the chimney. It gives up to 50% more heat transfer compared to other non water-cooled, non brick lined designs.

C. Full length quad-pass heat exchanger and upper baffle

The Ultimizer heat exchanger runs the full length of the boiler. It is completely surrounded by water which gives maximum heat transfer

D. Water-cooled rear baffle

The water-cooled baffle at the rear of the Ultimizer fire pot absorbs heat and traps combustion vapors. Turbulence is created when air is introduced from below and above the fire. This turbulence provides an optimal burning environment for the vapors, leading to a hotter and more efficient burn. Also, by trapping the vapors, they are thoroughly burnt before entering the high efficiency heat exchanger. This heat exchanger is totally surrounded by water for maximum heat transfer.

E. Sectional, easy to repair design

Not a throwaway design like other brands are. The Ultimizer weighs substantially more than other brand boilers. That’s due to the heavy weight, long lasting, quality materials that go into our design. It provides a long-term, sustainable solution to your heating needs. At the end of its long life, the water jacket can be replaced. Just remove the top half of the boiler and bolt on a new top section, no welding required and your trusty boiler is good to go again. This means a very sustainable warranty, resulting in savings for the customer of several thousand dollars by rebuilding rather than replacing the entire boiler.

Q. My current outdoor boiler had constant issues with the water jacket, how expensive is it to repair this unit?

The water jacket comes up a lot with customers who’ve used a water boiler before as this is the most frequent point of failure on boilers. Water jackets frequently fail because of ash-line corrosion – our dry-base design has eliminated this. Further to this, ¼” thick cold-rolled steel is used to make the firebox; 2x as heavy as what some competitors use.

Most outdoor boilers are built around this water jacket in such a way that repairing is usually not offered as a warranty solution. Issues requires full dismantling of the boiler and shipping out, or waiting for someone experienced in welding and water jacket repairs to get to you. Both “solutions” often result in days of lost heating. Most warranties will mean a complete replacement of the whole unit.

At Portage & Main, our equipment is built to last, not to be tossed in the junkyard. Should problems with the water jacket arise, it has been built as a separate component within the unit’s sectional design. Simply unbolt and replace or repair on-site within just a few hours. This repair would be 1/3 – ¼ of the cost of competitors.

Furthermore, as EPA standards and levels change, it is nice to know you have rebuildable unit that you can keep, repair and next generations can use far into their futures.

Q. Is the cost of an outdoor wood boiler of this size and style really worth it?

Trying to determine whether the upfront cost of a wood boiler of the size and quality of the Portage & Main Wood Series Ultimizer is worth it will depend a lot upon the household itself and lifestyle factors. We believe the biggest point of worth is that this system offers a reliable degree of energy independence and sustainability for both residential and commercial use. For those living on farms, acreages, or off-grid locations and businesses, a wood boiler is a reliable heating solution. Even when one has access to utilities, having your own outdoor wood boiler means you don’t have to worry about the rising costs of utilities or potential disruptions from storms or other events. Rather, you get to enjoy reliable, sustainable heating by your own design and that’s a long-term benefit that many find well worth the upfront purchase and installation cost. This gives peace of mind, knowing you can run off the smallest most fuel-efficient generator.

And we do mean sustainable. In a recent interview regarding how to be greener at home, executive director of the Massachusetts Forest Alliance Chris Egan explained that while oil and gas boilers have gotten cheaper, the big benefits remain with wood boilers, stating, “you’re reducing your carbon impact and you’re saving money with a wood system.” It’s the only fuel you can harvest yourself, from your own land in many cases. It’s carbon neutral: the sun and carbon grew the tree, the carbon is released when burned, giving back to future forest growth.

Q. This is my first outdoor wood boiler, how hard is it to care for ?

The Portage & Main Ultimizer Wood Series was built to be exceptionally easy to use and maintain.

• The control panel at the back is easy to navigate with quality components that, should they ever need to be replaced, can be readily bought around town.
• The clean-out chamber is designed for easy disposal of ash that’s dropped through the grating.
• The heat exchanger is easy to clean as build-up is minuscule due to the smoke burn in the upper chamber of the firebox. You pull the small amount of soot forward, then push it back into the firebox – keeping all the mess inside the unit.
• The water float system readily and quickly identifies your water levels.

The whole unit has been thoughtfully designed to be approachable and easy to use and maintain, while likewise ensuring durability throughout all the winters it’s in use.

As Old Man Winter blows cold throughout the hemisphere, it’s easy to rely on modern conveniences to keep your family safe and healthy. With rising costs of fuel and groceries, however, you may be rethinking your strategy for the season where the temperatures drop and the world freezes over.

Is there a better way to face the chill ? Does everyone have to make a choice between caring for their family and going broke ? If you have the lifestyle to consider other options, two ways to start are by heating your home with wood and canning your own food, ensuring you stay both warm and fed throughout the coldest months. As an added bonus, implementing these two practices will teach you and your family more about the value of hard work and healthy living.

Let’s take a look at six tips that help you along the path of practicing self-sufficiency during the coldest months of the year.

Tip 1: Plan Ahead

The time to start think about preparing for winter is early spring before the ground begins to thaw. How well did you make it through the winter? What would you do differently next year? It’s easy to get sidetracked and begin thinking about all your spring and summer plans, but take a big step back and consider your long-term vision for the entire year.

If you decide that you want to try heating your home with wood and canning your own food, there are additional factors to consider. Do you currently own a wood-burning stove or do you need to acquire one? Where will you get your wood? Also, what foods does your family regularly eat? Are you able to can those items in bulk before winter or would it be too much of a hassle? What kind of foods will you can, and how will you get your produce?

Tip 2: Do Your Research

Before you take any specific action, take some time to do some research about what it would take for you to develop self-sufficiency for the next winter. In terms of heating with wood, do some research about the different options that are available to you. Would you want to invest in an outdoor wood boiler or an interior wood stove? If the former, are there any regulations that your local municipality has on these furnaces? If the latter, do you have the right setup or would you need to restructure part of your house, and what would that involve?

Then, it’s time to research your options about canning produce for the winter. Are you going to grow your own garden, or is there a local farm that you can work out a reasonable deal for the produce you want to preserve? Most likely, you will want to do a little of each, especially if you hope to can fruits or if one of your crops does not do as well as you hoped. Look into each of these scenarios, and see what will work best for you.

Tip 3: Gather Your Supplies

Let’s assume that you have all the knowledge you need at this point and decide it is time to move forward with both plans—heating with wood and canning your own produce. Now, it’s time gather your supplies. Recognize that this will require some investment throughout the spring, summer, and fall, but the rewards will pay off once you are enjoying the fruit of your labors in the dead of winter! To get you pointed in the right direction, here is a starting list of the supplies you will need for both projects:
A wood-burning stove, either an interior design or an exterior one.

A reliable resource to help you with your new wood-burning adventures like Portage & Main Wood Boiler.
Plenty of clean, dry wood for the stove, whether this means cutting down trees on your own property for processing; having stripped tree trunks delivered that must be cut, split, stacked, and cured; or working out a deal so you have cured wood provided for you. A canning pot with an inner rack, jar tongs, and funnel. Plenty of jars with lids and seals. Fresh food to can, including fruits, vegetables, and possibly even some cuts of meat. A canning guide, such as The All New Ball Book of Canning and Preserving.

Tip 4: Talk to Experienced People

Remember that helpful associate at the hardware store who you overheard talking about his outdoor wood boiler? Or how about that lady at the local nursery who loves to talk about gardening? Perhaps you have friends who have experience in both of these areas, or you have been talking to a neighbor about taking on the venture together.

Whatever your particular circumstance, take the time to talk to people who have more experience than you in taking on winter with a self-sufficient mentality. Your research, of course, will point you in the right direction, but it can only take you so far. Having real, live people to turn to when you need a practical answer makes all the difference when you are in the middle of a new adventure. In addition, individuals with experience will provide extra tips and tricks that may give you that extra boost when you are realizing how much hard work goes into the process.

Tip 5: Get Down to Business

 Now, it’s time to put all your research into action! If you’re planning to process your own wood, set aside time to work on cutting down trees, sawing up the logs, splitting each log into sizeable chunks, and stacking everything so that it can cure by the time winter arrives. Alternately, if you are having trunks, logs, or split wood delivered, you can adjust your work load to prepare for those tasks. Either way, give yourself adequate time so that the wood has time to dry out before the next cold season rolls around.

For your canning preparations, there are also a number of different options to consider. Are you growing your own produce? If so, the time to start planting a garden is right around the corner! Or, if you will be working with a local farmer to obtain your produce, consider visiting them on a semi-regular basis to chip in and understand the process of the growing season. Once the produce is ready, then the next busy phase will require you to put in the hard work of canning and preserving the right amount of goods for your family.

Tip 6: Don’t Give Up

In reading all of these different details about the work involved to prepare for winter’s blast, it may be exciting to think about starting and getting into two new projects. However, once you are in the middle of the journey, other things in life may be calling to you from all different directions, and you may be tempted to give up before the entire job has been completed. Now is not the time to quit! Since you already determined that this is an important goal to reach and a path that you are passionate about taking, dig in your heels and resolve to finish strong.

Of course, everyone’s life circumstances are different, and some unexpected situations may require that you adjust course. If you find out in the middle of the process, for instance, that the financial costs and time commitments for canning your own goods and preparing your own wood is too great for you at this stage, then determine if there is another way to navigate those unexpected challenges.

On the other hand, perhaps your reason for wanting to give up is because you thought it would be easier to learn self-sufficiency and are feeling averse to the hard work involved. Take some time to talk to the experienced people you met along the way for an additional dose of reality, and then go back to your goals for extra motivation to complete the course.

Tip 7: Celebrate Your Success

Imagine that the next winter has arrived and you are enjoying the fruits of your hard labor. In your basement, the shelves are lined with many canned goods—for example, tomato sauce, green beans, pickles, corn, peaches, and pears. Your living room is nice and toasty for family evenings together as warm air is piped in from your outdoor wood boiler. What an accomplishment! While there have been bumps along the road and part of the learning curve has been rather steep, your perseverance has paid off for the benefit of your whole family. It’s time to rest and relax for the evening in comfort, a well-deserved reward for all your hard work!

Embracing the Off-the-Grid Homestead Life with an outdoor Boiler for Your Home and Farm This Winter

It is 6 AM and the first rays of sunlight are just beginning to appear above the horizon. The muffled clucks of awakening chickens come from a nearby coop while the squeal of a hungry piglet echoes from a hut across a misty field.

As the sun rises in its full glory and melts the fog that lingers between the rows of lettuce and snap peas, a brother and sister emerge from a house hidden behind tall oak trees and make their way to the nearby animal shed. It’s just a typical morning on a modern-day off-the-grid homestead!

In today’s world of modern conveniences and advanced technology, many people wonder why some choose an off-the-grid lifestyle. It requires a great amount of hard work and dedication, in addition to presenting many challenges and frustrations. In return, however, the benefits are rewarding, from learning how to work hard to providing for oneself and one’s family even in the case of technological failure.

This last element is particularly helpful to consider. With the increase of technology comes a greater risk when such features fail. It’s great to have electricity, running water, grocery stores, and other modern conveniences, but if they ever become unavailable, you need to know how to take care of yourself and your loved ones!

Let’s take a look at two areas where you can avoid dependency on the grid and live off the land. When you learn how to work the land, grow a garden, raise animals, and process the fruits of your labor, you will not only be happy, healthy, and satisfied, but you are at a great advantage over those who are unfamiliar with a self-sufficient lifestyle.

Raising Animals

First, let’s talk about four animals that are a perfect choice when deciding to grow your skills in self-sufficiency. Each of them will require some kind of shelter, an area to roam, the right feed, and plenty of fresh water. Since all of these animals are on the smaller side, you can be economical by using huts, sheds, and coops with attached fencing rather than constructing an entire barn.

In terms of the feed, there are many commercial options. Since we are in a self-sufficient frame of mind, however, consider researching the specific nutrients that your breed of animal needs and how you can grow the appropriate grains to sustain them.

Chickens

These birds are easy to raise, helpful in controlling bugs around your yard, and provide a great supply of eggs and meat. Depending on your needs, choose a breed that fits your lifestyle. For example, a flock of Rhode Island Red hens will put you in the egg business while raising Cornish Cross will provide you with fast-growing, stocky birds that are perfect for meat.

Rabbits

While not often thought of as a homesteader’s animal, the rabbit is a great choice if you are looking for a quiet, low-maintenance animal as a source of meat and fur or wool. Beyond the pet and show breeds, many kinds of rabbits are an economic choice for farm-to-table. Rabbit meat is healthier and easier to digest than chicken, and when the hides are carefully tanned, the furs are soft and warm. Alternately, look into getting an Angora rabbit, which provides wool that can be spun into yarn.

Pigs

Bring on the bacon! Besides being yet another source of meat, the pig is an alert, intelligent, and resourceful animal that is a perfect guard for your empty plots of earth in between each growing season. Since pigs use their snouts as a shovel, they are also happy to dig up a bare plot of ground and deposit their manure there for you

Goats

Sometimes thought of as the poor man’s cow, the goat is a great option if you are looking for a source of delicious milk. Their meat can also be eaten if you have the right palate for it, but the goat’s true value beyond providing milk is in clearing brushy areas and providing compost for your garden. Since they are stubborn and agile animals, goats will certainly test your patience and help your continued growth in self-sufficiency! Now, with your little farmyard complete, let’s turn to the ground and think about the best things to grow as food for you and your family.

Growing Garden

If you ever thought about growing a garden, you already know that the options are truly unlimited! Start with learning about your growing zone and soil type, since that will determine the types of plants that will do best in your area. From there, with timely planting and the right care, you can harvest for many months, from lettuces in the early spring to pumpkins and potatoes in the fall. Better yet, when your harvest comes in, canning and freezing will prepare you to continue eating the bounty all year round!

Every step in the gardening process has plenty of excitement associated with it. Even though you may be entirely new to this type of self-sufficient living, think about gardening as a great adventure where you discover the amazing power of plants and how you can participate in the natural process by weeding and watering, trimming and tasting. Another wonderful thing is that you can use seeds from this year’s crops to prepare for the next growing season! Best of all, you can be assured that you are providing yourself and your family with healthy and nutritious meals every time you prepare foods right from your ground. Self-sufficiency at its finest!

Now, let’s take a look at several groups of plants that every new gardener should consider.

Springtime Greens

This includes lettuce, chard, kale, and spinach. For the ambitious gardener, there are other cold-loving plants like peas, carrots, beets, and radishes to plant as well. Besides being tender and tasty, early-season lettuces can be planted in rotation throughout the season for a continuous harvest. Then there is the hardy kale that lasts well beyond frost!

Hardy Nightshades

These are your tomatoes, peppers, eggplants, and potatoes, perfect for preserving. Within each group, there are many other options depending on your specific needs. For instance, if you are growing peppers and you like spicy foods, go with jalapeños and serranos instead of only bell peppers.

Savory Herbs

From “parsley, sage, rosemary, and thyme” to basil, chives, oregano, and tarragon, you cannot go wrong by planting a variety of herbs! Not only do they add fresh flavor to your meals, but they can be dried for the winter and have many different medicinal purposes.

A. Refractory Brick Lining

The Portage & Main Ultimizer is a refractory lined, dry base boiler. In the industry it has become known as an “updraft gasifier” because of its efficient burn. The Ultimizer is simple to use, easy to maintain and not fussy about the fuel it burns. It is very important to understand the “fire triangle” in order to fully appreciate the advantages of the Ultimizer design, and how it will save you fuel, money and time. To achieve a clean, efficient burn with complete combustion, an optimal balance of OXYGEN, HEAT & FUEL is required. The Portage & Main Ultimizer has been specifically designed to achieve this optimal balance.

Dry base design, zero ash line corrosion & no bridging 
The heat stored in the refractory lining helps ensure that a more complete combustion process occurs. I.e. fuel is reduced to charcoal in a 3-stage process.

STAGE 1: The fuel is heated to evaporate and drive out moisture. This starts at 212 degrees F

STAGE 2: It starts to break down on a chemical level at 500 degrees F. Volatile matter is vaporized. These vapors contain 50% to 60% of the heat value of the fuel, making it imperative for them to be burnt properly at a temperature in the range 1100 degrees F for maximum combustion efficiency. When all the volatile gases have been released, the remaining material is charcoal

STAGE 3: Charcoal burns at temperatures in excess of 1100 degrees F. Latent heat also helps in the re-ignition of the fire at the start of the next burn cycle. It also helps to dissipate moisture that is a result of the combustion process. The dry base boiler design gives a very hot burn. The water jacket sits above the brick line so it isn’t up against the fire, taking away the heat prematurely. This eliminates ash line corrosion and the fuel is completely burnt, resulting in considerably less ash.

B. Air from above & below

Exhaust gases make their 1st and 2nd pass at the top of the firebox where they move under and around a water-cooled baffle and into the heat exchanger. Gases then travel to the front of the boiler in a 3rd pass, make a 180 degree turn and move in a 4th pass to the back of the heat exchanger. In this way, all available heat is taken from exhaust gases before they exit the chimney. It gives up to 50% more heat transfer compared to other non water-cooled, non brick lined designs.

C. Full length quad-pass heat exchanger and upper baffle

The Ultimizer heat exchanger runs the full length of the boiler. It is completely surrounded by water which gives maximum heat transfer

D. Water-cooled rear baffle

The water-cooled baffle at the rear of the Ultimizer fire pot absorbs heat and traps combustion vapors. Turbulence is created when air is introduced from below and above the fire. This turbulence provides an optimal burning environment for the vapors, leading to a hotter and more efficient burn. Also, by trapping the vapors, they are thoroughly burnt before entering the high efficiency heat exchanger. This heat exchanger is totally surrounded by water for maximum heat transfer.

E. Sectional, easy to repair design

Not a throwaway design like other brands are. The Ultimizer weighs substantially more than other brand boilers. That’s due to the heavy weight, long lasting, quality materials that go into our design. It provides a long-term, sustainable solution to your heating needs. At the end of its long life, the water jacket can be replaced. Just remove the top half of the boiler and bolt on a new top section, no welding required and your trusty boiler is good to go again. This means a very sustainable warranty, resulting in savings for the customer of several thousand dollars by rebuilding rather than replacing the entire boiler.

The Portage and Main Ultimizer Quad Pass Heat Exchanger

Portage and Main Ultimizer Outdoor wood furnace’s design and robust, quality manufacturing ensure that their furnaces achieve hotter, slower and more balanced burn which means higher efficiency. An efficient burn requires a balance of three elements:
Fuel, Oxygen and Heat

What is a heat exchanger?

Simply defined, a heat exchanger transfers heat. In a Portage & Main outdoor wood furnace, this heat exchanger transfers heat from the firebox to water surrounding the chamber. How is the heat exchanger designed and constructed?

Portage & Main have a unique Quad Pass designed heat exchanger. The design includes a water-cooled baffle at the top of the firebox. The heat then moves to the heat exchanger which is surrounded and separated by water-cooled walls and dividers.
This design makes the transfer of heat extremely efficient.

Double welded boiler style joints are exclusive to Portage & Maine outdoor water furnaces. All parts are laser-cut for precision fitting which allows the bevel to be double welded for total penetration welds. The fire chamber and heat exchanger are made a quarter-inch w44 cold roll mild steel which eliminates the problems associated with other metals.

How does a Portage & Main heat exchanger work?

First: After the fuel, heat and oxygen mix to create a balanced burn, some heat energy is transferred first to the water jacket surrounding the top of the firebox.

Second: Air is introduced above the fire which help burn the smoke and gasses. There is a baffle near the back of the fire chamber which serves a dual purpose. The baffle is water-cooled so absorbs heat but also traps the hot gasses and smoke. This trapping of gasses, oxygen and fire creates combustion storms which causes the fire to burn hotter.

Hotter burn = complete combustion = best efficiency

Three and Four: After combustion, this exhaust heat then travels horizontally through the heat exchanger at the top of the furnace. This is an industry-leading, 180⁰ reverse turn, water-cooled chamber that runs the full length of the furnace. This results in the largest heat transfer area of any updraft boiler design.

The Portage and Main chimney exit out the back of the furnace versus cutting it short out the top like other furnaces. This added length means more heat absorbed to the surrounding water and less heat escaping. Its dual chamber design, fully surrounded by water, and added length results in maximum heat transfer resulting in low temperature chimney escape.

Choosing a Boiler for Your Home and Farm This Winter

Winter is fast approaching, making now a perfect time to start thinking about how you want to heat your home and water for those cool days. There are a dozen different ways you might accomplish the task, but if you’re looking to keep your long-term costs low and live as sustainable as possible, then an outdoor boiler is one of the best options.

Set just outside the home, the outdoor boiler works by heating up a special jacket of water surrounding the upper portion of the firebox where wood is placed and burned. Once heated, the water gets pushed on through insulated piping to a home or outbuilding where heat is distributed into the air via an integrated system like radiant heating pipes or a water-to-air heat exchanger. So, while a home’s boiler may be located just outside its walls, this is a wonderful piece of machinery that serves as the beating heart of a home, providing heat to all of your property’s buildings.

So, why choose the Portage & Main Ultimizer Wood Series outdoor boiler?

Let’s look at the reasons why Portage and Main is the very best outdoor boiler available today.

Why I Chose the Portage & Main Ultimizer Series

First off, I like the wood series product by Portage & Main because I enjoy using wood as a natural resource – I can harvest the fuel myself! It is quite arguably the best natural, renewable resource we have. Not only are we readily, sustainably growing it throughout the country (when you’re not doing so on your own property), but often healthy forests require sustainable thinning–such as Idaho which estimates about 8 million of the state’s forestlands need thinning (“What Makes Wood Products So Green?” Idaho Forests, n.d.).

Forests are essential to our lives. Forests provide us materials to build and heat our homes and forests clean our air. The forest industry also employs many people to provide for their families.

Burning wood also harkens back to a favorite activity, camping. At the campsite, that fire pit is the centerpiece of the campsite. As evening temperatures drop, we gather around for the warmth and comfort a campfire provides. Gathering, cutting and layering the wood makes for something of a social activity and that fire we build up offers other benefits like the ideal setting for roasting hotdogs and marshmallows.

In fact, the Portage & Main Ultimizer operates a lot like that campfire that is surrounded by brick which absorbs the heat and gives it back to the fire resulting in less smoke and more efficiency. What makes the Ultimizer the best outdoor boiler on the market today is how fast and efficiently it gets those energy-packed coals going so that owners enjoy wonderful hot water and heated air throughout their home and any additional property buildings they might have connected. As we will soon see, all boilers, stoves and fireplaces will greatly benefit the cleaner burning with the use of fire brick of sufficient quantity the hold and give back heat to the fire

What is an Efficient Burn

Portage and Main’s Ultimizer design and robust, quality manufacturing ensure that their furnaces achieve the best, hottest and most efficient burn. An efficient burn requires a balance of three elements: Fuel, Oxygen and Heat

What is refractory brick?

Historically, bricks have been used to contain fire and absorb heat. Whether it be in a simple outside firepit, kilns, fireboxes or in the lining of an industrial chimney. Because it won’t burn, brick creates a great barrier between the flames, other combustibles, and people who are using the fire. A refractory brick’s composition withstands extremely high temperatures, resists melting, and has low thermal conductivity (even lower than concrete) which aids in energy efficiency.

Hotter Burn = Balanced Burn = Superior Efficiency

• Combustion Balanced Design
  

P&M refractory bricks on the lower portion of the firebox do not come into contact with the water jacket. There is no water behind the refractor. This allows the firebox to burn very hot without losing heat to the surrounding water. Other brands’ fireboxes are surrounded by the water jacket which pulls heat away from the fire preventing a hot burn and therefore, the combustion is not balanced. Portage and Main firebox burns extremely hot reducing fuel consumption.

Combustion is balanced when the fire burns hot and doesn’t depend on more wood to keep the temperature up.
Portage and Main understands that burning the hottest fire is essential to saving time and money! This refractory brick designed firebox lining results in superior efficiency and balanced combustion.

How are competitors fireboxes designed & built?

Our refractory brick lined firebox design is unique to Portage and Main. Other brands’ fireboxes are encased in the water jacket which absorbs heat preventing the fire getting to its hottest, most efficient burn. This design just doesn’t make sense if you want an efficient burn. Building and designing with refractory bricks costs more but makes sense. The bricks are the key to the hottest, best, most efficient burn possible.

Other brands fireboxes bases are completely cooled by water, it never completely dries; leaving moisture at the bottom which can cause corrosion and the necessity of raking ash more often.

Our competitors have not duplicated our design as it is costlier to manufacture a more effective product. The other brands will price their product competitively to Portage and Main, but is a lesser efficient product; Portage and Main is, by far, the best quality and most efficient.
