Frequently asked questions

One easy way is to look at the BTU output of your current furnace. If you are going to burn coal only then you can get a furnace of the same size or larger. If you are going to burn wood then it is a good idea to double the BTU amount and buy a furnace that size or larger. The reason for this is that many times when burning wood you will have wet, green, or poor quality wood that takes more wood to burn efficiently. You do not want to be faced with having to fill your furnace more often then a couple of times a day.

Do I need to poor concrete to set the unit on?

We do recommend concrete. The pad should be at least 6'x6' for all of the furnaces above, but 6'x12' gives you more area in front of the furnaces to clean and to stand on when filling. The furnace can be set to the rear of the pad with the rear of the furnace overhanging the cement so the underground pipes and electric can still get into the furnace. Some people do set them on cement silo staves or other blocks. This will work but care must be taken to make sure they are set solid and level. Remember that water weighs 8 lbs per gallon so the unit can be rather heavy when loaded with water and wood.

Does an instruction Manual come with the furnace?

Yes it does. It also explains some installation scenarios.

I have a forced air system in my home. How big of a water to air heat exchanger do I need?

You will want to measure your plenum size and get the largest one possible for this. The larger the heat exchanger the more heat you will get.
