I'm feeding a HX in a forced air furnace and want to retro fit the house for baseboardand run a low temp of water (140f). I am heating about 3500 sq.ft. and figure the heating load a little over 100kbtu/hr. I think about 200 feet of baseboard will work nicely and I envision 3 loops downstairs and 1 upstairs. My existing furnace is an open loop geothermal with a desuperheater installed.I'd love to hear from anyone who has done something similar. Question - Can I feed the baseboard directly from the Garn in a series loop? Does it make more sense to establish a pressurized closed loop and use a water to water HX to heat a storage tank. If so, can I use the geothermal to heat that as well via the desuperheater? Thanks in advance for your thoughts.
