Electric heating options when on shore power?

Our HTT has propane heat, but when it is cold (as it was this past weekend), it can run A LOT.

First check the operation of the propane furnace. Especially the ducting needs to be open and clear moving lots of hot air. If the furnace burner cycles while it is in the heating mode then you have poor air flow.

Otherwise I use a 1200 watt radiator style heater to supplement the furnace when temperatures are expected to approach freezing or below.
