Is an electric wall heater expensive to run?

A timer switch that limits the heater to morning routines stops it from quietly running all day. At typical use it adds about $30.08 to a monthly electric bill at the US-average rate, but that swings from $21.01 in the cheapest states to $78.22 in the most expensive.

How many watts does an electric wall heater use?

Electric Wall Heater typically draws about 1,500 running watts. It's a resistive load, so its startup and running wattage are the same. Check the nameplate or label on your specific unit for its exact rating.

How much electricity (kWh) does an electric wall heater use?

At typical use (1,500 W for 4 hours a day), an electric wall heater uses about 6.0 kWh per day — roughly 183 kWh per month, or about 21% of what the average US home uses in a month (863 kWh). Energy used doesn't depend on your electricity rate — only the bill does.

How can I lower the cost of running an electric wall heater?

A timer switch that limits the heater to morning routines stops it from quietly running all day. You can also cut the cost by lowering your electricity rate — many utilities offer cheaper off-peak hours — or simply by running it fewer hours. The calculator on this page shows how changing hours per day or your electricity rate moves the number.

How Much Does It Cost to Run an Electric Wall Heater?
