Hey all I am getting ready to source and install a radiant floor heat system. I hope to utilize a pellet boiler with unpressurized storage.
Design intent is as follows....
convert from electric heat to pellet....(I dislike firewood cutting and such)
cover the time away from home ( I work 24 hr shifts)
some numbers I have come up with
heat load for the house 47520 btu/hr rounded up to 50000
2200 gal storage tank at a design temp of 170 F = 3104200 btu
3104200/50000 = 62 hrs of storage or 2.5 days
using 50000 btu to recharge said tank will take approx. 26 hrs at 70% efficiency.
using those numbers I have come up with a 100000 btu/hr needed for a boiler.
comments suggestions and or critics welcome and requested !
Thanks in advance !
Sean
