How Much Does It Cost to Run a Baseboard Heater in Colorado? (2026)
Electric baseboard heaters are sized to the room, typically 500 to 2,500 watts, and are pure resistance heating. Every watt becomes heat, but electricity is an expensive way to make heat compared with a heat pump.
A typical baseboard heater (1,500 W) costs $0.26 per hour, or about $45.90 per month at 6 hours a day in Colorado. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (500 W) | $0.085 | $0.51 | $15.30 | $186.15 |
| Typical (1,500 W) | $0.26 | $1.53 | $45.90 | $558.45 |
| High (2,500 W) | $0.43 | $2.55 | $76.50 | $930.75 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 6 h/day ≈ 3,285 kWh per year.
One hour of a baseboard heater (1.5 kWh) is the same electricity as
- 8.3km in an electric car
- 15hours of TV
- 33hours of a laptop
- 167hours of an LED bulb
In Colorado, with electricity at $0.17 per kWh (source: EIA Table 5.6.A, 2026-06), a typical baseboard heater costs $0.26 per hour and about $558.45 per year at 6 hours a day. That is about 6% less than the national average for the US ($48.60 per month), because electricity in Colorado costs $0.17 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 3.9 hours of use.
How to lower the cost of running a baseboard heater
- Fit a programmable thermostat per room and heat only occupied rooms.
- Keep furniture and curtains at least 15 cm clear so heat can circulate.
- Seal drafts around windows in rooms with baseboards. They cannot overcome a leaky room.
Frequently asked questions
How much does a 1,500 watt baseboard heater cost per month?
At 6 hours a day it uses 270 kWh a month. Pick your region above for the cost.

No. They draw nothing between heating cycles.
Are hydronic baseboard heaters cheaper?
Not per unit of heat. They hold warmth longer after switching off, which feels more even, but the electricity used is the same.
