"Huge money saver"

5.0 rating
Very Satisfied

I've had the furnace for 4 years and it has been great. Fill it twice a day when it's really cold and only once when it's in the 20-30 degree range. I like the fact that it's stainless, so it will not rust out.



"HeatMaster, yeah!"

We purchased this Furnace in December 2013 and have been very satisfied with it. The heat it produces is always consistent. The size of the wood it takes is perfect for handling. We never have to adjust the thermostat. We set it and forget it. The amount of ashes it produces is acceptable. The service we get from the manufacturer is great, whether it is just a question or a bigger issue we always get satisfaction. We would definitely purchase this brand again as well as recommend it to others.

"Best Investment Ever"

5.0 rating
Very Satisfied

I was on budget billing heating with electric and paying $585 per month. Now with our HeatMaster 250, I am paying $73 per month. It's like getting a $500 per month pay increase. The HeatMaster heats my 33 x 73 shop and all of our hot water, and we are only burning about a pickup load and a half a month to do it. Great furnace!
