Electric Baseboard Heat and a Huge Bill? Why It Happens and 7 Cheap Fixes (Renters Too)

Baseboard heat is simple, quiet and in millions of apartments, and it can produce a shocking January bill. Here is what each room actually costs, why the old dial thermostat is the real problem, and seven fixes from free to an afternoon’s work.

I’ve had baseboard heat in more than one of my rentals, and the pattern is always the same: tenants set the dial to “5,” the room overheats, they open a window, and the bill comes in at double what they expected. The EIA expects electric heating bills to be higher this winter than last. The good news is that baseboard heat is the easiest kind to control room by room, once the thermostat lets you.

Short answer

Baseboard heat is expensive because electric resistance heat costs more per unit than gas or a heat pump, and old dial thermostats overshoot and never set back. The biggest fix is a line-voltage programmable thermostat such as the Honeywell 5-2 day for baseboards, then turning down unused rooms, sealing drafts and keeping furniture and curtains off the heaters.

Cost per room calculator

What does this heater cost?

“Hours heating” is the time the heater is actually on, not the time the thermostat is set to heat; in cold weather a heater may run half the time or more. Your price per kWh is on your bill.

Why the bill is so high

7 cheap fixes

  1. Turn down rooms you don’t use to 55–60°F and close the doors.
  2. Keep 12 inches clear in front of every heater: no furniture, curtains or drying laundry.
  3. Vacuum the fins once a season; dust insulates them and smells when it burns.
  4. Seal drafts at the windows above the heaters and under the doors. A door draft stopper 2-pack costs very little; owners say it blocks drafts, and adhesion is the usual complaint.
  5. Use thermal curtains that stop above the heater, not over it: see best thermal curtains.
  6. Heat yourself at night with a heated mattress pad or blanket and set the bedroom lower: see heated blanket vs space heater.
  7. Replace the dial with a programmable line-voltage thermostat, below.

Thermostats that fit baseboard heaters

Safety first: baseboard thermostats are line voltage, often 240V. Turn off the breaker and confirm the power is off before touching wires. If you rent or aren’t comfortable, hire an electrician; it’s a short job.

ThermostatTypeWhat owners say
Honeywell Home 5-2 day programmable (baseboard)Programmable, 4 periods a dayEasy 5-minute swap, good temperature control; one owner saw about a 10% drop in the bill; a few report button problems
ELV4 programmable line-voltageProgrammableEasy to install, pays for itself quickly; some note loud clicking
Cadet double-pole line-voltageNon-programmable, accurate dial upgradeEasy install; one owner says it reads several degrees off
meross Matter smart thermostat for baseboardsSmart, app and voiceEasy wiring and remote control; Wi-Fi drops for some
Mysa LITE smart thermostatSmart, appSimple install, nice app; check compatibility with your wiring

Before you buy: check the voltage on your heater (120V or 240V), whether the old thermostat has two wires or four (single- or double-pole), and the total watts on that circuit against the thermostat’s rating.

FAQ

Why is my electric baseboard heating bill so high?

Baseboard heaters are 100% efficient at turning electricity into heat, but electric resistance heat costs more per unit of heat than gas or a heat pump. A 1,500-watt heater running 8 hours a day uses about 12 kWh a day. Old dial thermostats also overshoot and never set back.

Do programmable thermostats work with baseboard heaters?

Only line-voltage models made for electric baseboard heat (usually 120V or 240V). Ordinary low-voltage thermostats for furnaces won’t work and can be dangerous. Check the voltage and whether your heater uses single-pole or double-pole wiring before you buy.

Can a renter replace a baseboard thermostat?

Ask the landlord first. It’s line-voltage wiring, so the breaker must be off and many people hire an electrician. Some landlords agree because it lowers the bill and the thermostat stays with the apartment.

Is it cheaper to use a space heater than baseboard heat?

Not per hour: both turn electricity into heat at the same rate. A space heater can be cheaper only if it lets you heat one room and turn the baseboards down everywhere else.

Should I turn baseboard heaters off in rooms I don’t use?

Turn them down, not fully off, in cold climates: around 55–60°F keeps pipes and walls from getting cold and avoids condensation. Close the doors to those rooms.
