Can anyone recommend a contractor to assist with the install of a gasification wood boiler with 1000 gal storage, propane backup, in floor heat? I am located in SW Wisconsin, near Prairie du Chien. The local people won't touch it as it seems it is too outside the box for them. Pex is installed, most of the equipment is here. I have an Econoburn 200 boiler and according to my calculation: gpm= btu/hr / (delta T x 500), at 200,000 btu/hr and a delta T between boiler out and supply return of (180F - 80F) 100F, my gpm to storage would be 4gpm. The contractor who came out and walked away said that my 1" pex supply and return to storage (60 foot run each way) wasn't capable of transporting more than 115,000 btu/hr. Dale at Econoburn said I could never move the boiler output with 4gpm and that it would go into shutdown. Even if the max output is closer to 300,000 btu/hr, that would only be 6 gpm. 1" pex seems to be rated for around 10 gpm....They keep talking about gpm, I keep telling them it's about delta T. What do I have wrong???? Would really appreciate any suggestions. Thanks.
