Hi
I have recently bought a 200,000 Btu wood boiler and am trying to sort out all the misinformation and information, in order to properly size my heat exchanger (for my airhandler) and lines from my boiler to my house.
My current heating system is a 52,000 btu heat pump w/electric heat strips. It works ok but it never shuts off when it is cold. The heat strips work fine when its cold but I dont like paying for them>
I also intend to enlarge my house by 576 sq ft this spring so I want to provide for the increased living area now.
I have looked at a lot of different web sites and I am seeing btu ratings for the same size exchanger vary as much as 50000 btus.
My boiler is going to be approx 150' from my house and I intend to heat my hot water and a large driveway.
I am an excavator and outdoor plumber so I understand the basics.
I need to know what the optimum GPM is for a system like this so I can size my pumps. I intend to have 100 gal of storage.
My HVAC contractor seems to think I need a minimum of an 18 x18 exchanger so as to not restrict the airhandler to much, but were completly useless on any of the other questions.
The dealer I bought my boiler from seems to be a hillbilly engineer and I just dont trust his information at all.
Another question I have is can I run one circuit to the house and then pull seprate circuits off of it for hot water and the driveway, or run a single circuit in series, (this doesnt seem like the best idea to me but I dont know) or run seperate circuits from the boiler.
Thanks in advance
