I had originally planned on installing a h frame for my electric service to feed my barn and future home. After talking to my well driller, pits are no longer allowed by code so my plan is to build a shed to house both my electric service and well plumbing/electronics so I can keep it above freezing.
This will be in Northern Indiana so cold and snow have to be dealt with.
Best way to build floor/footer to keep plumbing from freezing? I will run a small electric heater with 40 degree thermostat.
1. Stem wall with gravel floor? Run rigid insulation around exterior and under floor?
2. Concrete slab insulating the same way?
3. Rough in 4" pvc penetrations for electric and water? Do those(water?) need insulation down to frost line?
