I will be specific so that I don't upset anyone by using the term "wood boiler".. So, here I go. We currently have a natural gas "boiler" (hydronic furnace). We purchased a pellet stove this fall. However, it doesn't work that well for heating the whole house. We have it on the main floor of a ranch home. If we had it in the basement, we might get more even heat on the main floor. However, it is what it is. So, we are looking into getting a wood-fired hydronic furnace this summer/fall to act as our main heat source. We will use the pellet stove as a supplementary heat source in the dining & living room area of the house. And we will use our natural gas "boiler" as our backup. So...I am looking for recommendations on wood-fired hydronic furnaces... One brand that I have looked at so far is Greenwood. Any other opinions and/or recommendations would be greatly appreciated. We are looking for an indoor hydronic furnace for our basement. So, there is no need to suggest an outdoor hydronic furnace. We just don't want one, period. Bring it on Thanks..
