Anyone have experience with these? I have forced air oil heat now which I supplement with an Englander Add-On furnace. It has worked well for the last five years and saved me a lot of money, but in the winter our house gets as dry as a popcorn fart despite our best efforts to keep it humidified. Plus, we are planning on doing a large addition eventually (it's a 2 bedroom/1 bath ranch right now) that is going to require major changes to the heating and cooling systems anyway, so when we do that, we'd like to switch to a hydronic system. Gas is not available where we live and I don't want to switch to propane either. I was just doing some Googling and came across this company. I'd love to hear from someone that owns one and how they like it. http://www.mainewoodfurnaces.com/products/indoor-cc500/ From what I can tell it sounds like their dealers are all located in and around Maine. We live in NJ but go to Maine often, so I could easily trailer one back with me after a vacation.
