So I am currently heating my home with a Lopi insert. As expected there are some definite cold spots at the opposite end of the house and upstairs. Because of this I am thinking of installing a gassification boiler such as a Garn, etc. I want the boiler installed in a shed to be built to minimize the amount of handling of wood I have to do, and to minimize the chance of getting carpenter ants, termites, etc in the house.
The house is approx. 2400 sq ft, and I would like to heat the garage, my 525 gal hot tub, and a future workshop. House currenly has an oil fired FHA system as primary heat source.
Hot water is currently an oil fired hot water heater.
So what I am looking to do is this:
- Install boiler such as a Garn WHS2000.
- Pre-heat incoming water to hot water heater with a plate heat exchanger.
- Boiler outlet of plate heat exchanger goes to another heat exchanger in the FHA plenum and then return to the boiler.
- Another loop feeds a shell and tube type heat exchanger for the hot tub.
- Another loop to the garage where I plan to add radiant floor loops and pour some additional concrete over the top.
- Another loop for the future workshop to be built.
- An additional loop to another heat exchanger and a fan on the second floor to finally give me two zone heat.
I guess my biggest question is would the heat exchanger in the FHA plenum be efficient enough to make this worthwhile?
Would I be better off installing either radiant floor loops under the floors in the basement?
If I did that what would I do to heat the second floor? Would the heat exchanger fan combo be good enough considering the second floor would be kept cooler than the ground floor?
Any help and other high level design ideas would be greatly appreciated.
Thanks,
Mike
