Superior to an Electric Emergency Heat Source
March 18, 2026
We use this as an emergency heat source to our Geothermal Unit. It uses far less energy to operate than an electric source. The only issue was a control board failure, twice, to the booster exhaust fan. Once the control board was eliminated and booster fan control was tied into furnace primary fan control it has worked excellent.
