HeatMaster indoor (yes, some models can be installed indoors) and outdoor wood furnaces are made in Manitoba (Winkler, MB to be exact), utilizing Manitoba workers, expertise and innovation.

I recommend the HeatMaster Wood Furnaces because they satisfied my own OWF (outdoor wood furnace) requirements:

1.) Environmentally friendly As a firewood supplier we pride ourselves on providing sustainable, carbon neutral heating alternative (firewood) to fossil fuels such as natural gas, heating oil or coal. Our OWF needed to do its part to keep smoke emissions low and heat output high to reduce our environmental footprint.

2.) Heat multiple buildings / components Quality outdoor wood furnaces aren’t cheap and if I was going to pay good money I wanted our furnace to heat our home, garage, shop and hot water efficiently and economically. I view the purchase cost of our OWF as prepaying a hydro or natural gas bill in advance.

3.) Look good Our yard is where we live, work and play and the OWF would be a part of that. We wanted something that worked hard and looked good while doing it and looked like it belonged in our yard, not an industrial afterthought. Little to no smoke was a must have to keep us and our neighbours healthy.

4.) Easy to use / efficient Even though we supply firewood for a living and have firewood handy, I didn’t want to have to be always filling our furnace when I could be spending time doing other things (like soaking in out wood fired hot tub). I also wanted a unit that made the most of the firewood it burnt.

5.) Local support As a rule I like to buy Canadian and even better buy from a Manitoba supplier. This supports our economy as well as having a local contact for any technical questions, parts, best practices etc. It also saves on shipping.

6.) User references It’s pretty easy nowadays to have a professional looking website and impressive marketing materials. Whether it’s a truck, a furnace, a dog or whatever I always like to talk to people that actually own / use one before I buy.

When you purchase a HeatMaster furnace from Firewood Manitoba you'll get the following: 1.) Delivery of your wood furnace. These units weigh north of 1500 lbs. and not everyone has the equipment to load and unload that much weight. We'll bring your furnace right to you and make sure it gets to where it needs to go. 2.) Firewood. When you purchase a HeatMaster wood furnace from Firewood Manitoba you also receive a cord of firewood with delivery. That equals 128 cubic feet of stacked firewood. You have a great furnace, you deserve great firewood as well. 3. Help all along the way. Initial contact, receiving a quote, answering any questions you may have, delivery, training / commissioning, parts / service and after sales support are all included with purchase. You don't take purchasing your furnace lightly and we don't take supporting it lightly either. 4.) Partner support. If you would like help with designing your heating system, calculating how much heat you'll need, installation, plumbing etc. we can put you in touch with our local partners to help. 5.) After sales support. We are available 24/7 after your purchase for questions or help by phone, email or text. We guarantee to get back to you the same day you have a question. 6.) Firewood (again). Some people enjoy cutting, splitting and hauling firewood and some don't (or would rather spend their time doing something else). For those that would rather have their firewood delivered to their door cut and split we would be happy to help with that. For those that want some exercise but don't have the timber handy, we can put you in touch with our logging partners to supply logs for you to cut and split yourself. 7.) Trade in rebate. Do you have a stove you would like to replace? Not working, not efficient, smoking, needs repair, not enough heat? We provide trade in credits for your existing furnace, we'll haul it away when we deliver your new replacement. We'll need information on year, make, model and reason for replacing and then will get back to you with what is worth for a trade in. 8.) Firewood (last time I promise). We're happy to provide tips on efficient and economical ways of cutting / splitting, seasoning, transporting, storing and feeding of your firewood for your wood furnace. Just like your car or truck, your furnace runs best with the right fuel. We even have tips on what to do with your ash (great for the garden, slippery paths, de-skunking your pets etc.)


The components of a HeatMaster heating solution. 1.) A HeatMaster wood furnace can tie into your home heating and hot water system easily and very effectively. A radiator can be installed in to the existing plenum of your furnace and a water to water heat exchanger can be used to heat your domestic hot water. 2.) To heat the home or structure, the outdoor furnace pumps hot water indoors via insulated underground pipes. Once the water enters the structure, it travels through the traditional heating systems, including radiant baseboard, forced air furnace or radiant floor system and then circulates back to the furnace. 3.) Heatmaster outdoor furnaces come with easy access rear doors and ball valves on the furnace outlets making plumbing and maintenance quick and easy. Insulated underground pipe enters the rear of the furnace through the floor and connects to the furnace outlets. The pump is installed on the supply outlet to push water to the building being heated. Electrical wiring and components are set up on the furnace for easy wiring and servicing. 4.) The HeatMaster system is perfect for garages, shops and other outbuildings. It will supply heat to an overhead forced air heating unit or in-floor heating allowing you to use the existing heating appliance as a backup.
