Cutting the number down

Resistance heat is 1 kWh in, 1 kWh of heat out. There is no efficiency upgrade available; the only lever is running fewer of them, less often.
Furniture pushed against a baseboard blocks convection and makes the thermostat run the element longer.
Zoning by room is the built-in advantage. Turning unused rooms down to 55 F is where the savings live.
