Hello. I'm a newbie. We are building a new house and I'm going to put radiant heat in the floor, add a heat exchanger in a propane furnace to heat the upstairs, and do some minimal ice melt. Total heated space in house/garage will be 4,100 sq ft and maybe 350 sq ft of ice melt. As this is Kansas, the ice melt will get used very little. I cut and split all my own wood, I do not pay for it. I'm wanting input on the Eko Attack35. Is it a good unit? I've also looked at Econoburn, but the price is so much higher. Also, water storage. For now I don't believe I will put it in, possibly down the road I will. Can it be put outside (boiler is inside garage) as long as it is insulated well and not far away? Thanks for any help!
