I'm building a new house in climate zone 5 dry.
Average air temperature here is 41*F (5*C) so that is also the 10' deep soil average temperature.
I'm using 6" of EPS type 2 under my radiant slab and running down the inside of my foundation stem walls.
180' 1/2" pex-A loops 7” OC using constant circulation with Grundfos Alpha pumps on low, with Erie BB3000 injection Outdoor Reset controller.
Thermostats are Tekmar PWM type, that learn, with slab sensors.
