   This is an old idea form the 1950s from a time when we thought electricity would be too cheap to meter.

   This is pure resistance heat and will be very expensive to operate give todays cost per kWh.

   If you install a heat pump instead your bills will be a quarter of what resistance costs to operate.

   Thanks. We can get to -20F during some nights in Jan and Feb, so I’m not sure about heat pumps yet.

   My Rheem heat pump heats my house down to +6°F with the strip heat locked out.

   I do not feel bad about using the strip heat for the few hours each year they are needed.

   There are vapor injected heat pumps that run well at -15°F.
