I've been wanting 1 for a year now and just couldn't drop 7-10k on a new one because I just heat with woodstove with a heat pump for back up so the cost savings just weren't going to be significant. Well a guy local to me had a prosteel model 200 heating his 3000sqft home and dhw and he has a bad back and is moving so he wanted to sell the stove. It's 7years old and I am getting everything that is connected to the stove,pump, pex, valves,fittings , 2 heat exchangers with 1 being a custom mounted unit with a fan that is installed in his attic with ducts coming out like a octopus to heat his upstairs. Heck I even got his 22ton brave log splitter with a new motor on it. Will be able to get it all when his new house has the power connected in the next 2 weeks. I will really be reading and researching install info to get the stove ready for next year at my house. Thanks for the great site and all the info. Jonesy
