EcoRenovator - View Single Post - A7 AirTap install (ASHP hot water heater)

I checked out the heating elements and the draw at 120Vac is 1.130 kW. (3856 BTUh).

I plugged it into my solar backup cart, and let the sun to supply some 120Vac MSW juice for testing.
Within 25 minutes, the Tee sensor showed a 2 deg C increase.

So, I think using the heating elements at 120Vac might be a good method
of helping out the A7, when basement temperatures get real low.
The goal mainly, is to keep the A7 from long run times and lowering the basement temperature down into the uncomfortable range.
