I am considering hydronic floor heat for a small cabin:
Dimensions are as follows:
20x24 main floor
Full basement, wood foundation
2x6 walls with fiberglass insulation, no Tyvek, no inner moisture barrier
Roof is 2x6 or 2x8 with fiberglass insulation
1. What size PEX works best?
2. Do I need separate zones for loft, main floor?
3. Does loft even need tubing? Will heating main floor suffice to heat
Located central Wisconsin. USDA growing zone 4.
All loft and floor joists are exposed, so installing tubing between joists
Am also considering geothermal as the heat source. Domestic well water
--> heat exchanger --> discharge into pond. Is there a good reliable
source for equipment at discounted pricing?
