How to lower the cost
- Heat the person, not the house: electric blankets and heated throws deliver comfort for a tenth of a space heater’s draw.
- Every degree of thermostat setback saves roughly 1–3% on heating over an 8-hour stretch.
- Air sealing and insulation beat any heater upgrade — leaked heat is bought at full price.
