Hello,
I am FINALLY ready! I am building a 5' round x 5' high tank (pool metal) with epdm liner; around 900 gallons of storage.
I need your help and guidance!
My boiler is 130,000 btu & my system (as a temp setup) is hooked up in series: wood - oil w/ dedicated circ running constantly,(through tankless DHW on oil) I have 2 heat zones, circ based, baseboard. And right now I light 1 small fire a day because I do not have storage and do not want to overheat.
(but you guys knew that, lol)
I, so far, have 60' of copper pipe; 10' pieces of: 1-1/4", 1" & 3/4" (2 each)
I THINK I want 2 separate heat exchangers in the tank. 1 for DHW preheat and the other for boiler heat exchange, therefore the tank of water does not circulate.
Is that best?
(I would really-really like to minimize the amount of electricity required to run this system.)
Can I use the different sizes of pipe for heat exchange in each coil or should I go with larger pipe for boiler and smaller for preheat How much (length) do I need (minimum) for each run?
Thanks for your time and consideration in advance!
Scott
