Warmboard on slab versus PEX in slab
Basement floor will be lowered two feet and gravel bed, insulation, vapor barrier installed. Exterior walls (half height above grade) will be excavated and waterproofed.
Question: Can/should warmboard be used below grade in lieu of PEX in slab?
Will in-slab require higher water temp input for slab versus upper floor's Warmboard?
Will higher temps rule out use of geothermal water to water exchanger and force introduction of auxiliary heat source to generate additional energy required for slab?
