"Great Product from Heatmaster"

1.0 rating
Very Unsatisfied

This winter will be our third season using our Heatmaster. We purchased it from The Stove Depot in Lucas, Ohio.The boiler is used to heat our house and our 40×60 pole barn. We have been very happy with the boiler. We haven't had any issues with the unit at all. We did the installation ourselves and it was quite a bit of work but well worth it. The boiler has performed very well. The fan in the back of the stove keeps the fire going when the water temperature drops below 170 degrees. No worries about the fire going out like on a draft style stove. The removable ash pan and shaker grates make for easy ash removal. The large fire box door makes it easy to load larger pieces of wood. No need to split everything up really small. The large fire box only needs loaded 1-2 times per day even when the temperature outside is around zero degrees. We also have the option to burn coal in our boiler as well. When we compared a bunch of different brands of boilers, the Heatmaster came out on top.

4 years ago I bought a HeatMaster wood furnace after I had checked out all the other brands. I liked the rounded fire box and the fact it had shaker grates to burn coal This is probably the best decision I have made in my life. I heat my shop plus my home and it does an excellent job I have hot water baseboard heat in house it is easy to clean ash is easy to remove. All controls are easily accessed and function properly I have not had one problem with this stove I would highly recommend buying HeatMaster products
