The short answer

About 16.1¢ a night for a heated mattress pad and 14.6¢ for an electric blanket, running 8 hours at the US average of 18.31 cents per kWh (EIA, July 2026). Sunbeam states 110 W for its current mattress pad and 100 W for its blankets and throws. A 1,500 W space heater on high costs $2.20 for the same 8 hours, 15 times as much. Even in Hawaii, the dearest state, a blanket night is 38.4¢.

Sunbeam gives one wattage per product page, the same for every size. Throws switch off after 4 hours, so an 8-hour night means switching them back on.

Against a space heater

The same 8 hours at the US average. Heater wattage comes from the 21 current models in our space heater table.

The comparison is power, not comfort. A heater warms the air in the room; a blanket or pad warms you. If you need the room warm, the blanket does not replace the heater.

Method

Watts. The wattage on each Sunbeam product page's specification list, read by hand on 17 October 2026. We left out three Sunbeam mattress pad pages that search engines still show but that no longer load on sunbeamhome.com.
Price. EIA Electric Power Monthly, Table 5.6.A, residential price by state, July 2026.
Cost. watts / 1,000 x hours x price per kWh. Example: 100 W x 8 h = 0.8 kWh; 0.8 x $0.1831 = 14.6 cents.
Limits. Rated watts are the maximum. The cost at lower settings is lower, by an amount the makers do not publish.

Changes

2026-10-17: Published with 7 Sunbeam heated bedding products read from sunbeamhome.com, 21 heaters from Dreo, Vornado and Lasko, and EIA residential prices for July 2026.

Next step

Two sleepers who want different warmth need two controllers, which on a queen or king pad may double the draw. Check the controller label for the watts per side before you compare.

Common questions

How much does a heated mattress pad cost to run per night?

Sunbeam rates its current heated mattress pad at 110 W. Eight hours at that rating is 0.88 kWh, 16.1¢ at the US average of 18.31 cents per kWh (EIA, July 2026). If the two controllers on a queen or king each draw 110 W, double it with both sides on.

Is an electric blanket cheaper than a space heater?

Much cheaper to run. A 100 W Sunbeam blanket uses 15 times less power than a 1,500 W heater on high: 14.6¢ against $2.20 for 8 hours at the US average. The blanket warms you, not the room, so it only replaces the heater if you are in bed or on the sofa.

Do heated blankets use their full wattage all night?

The rated wattage is the most the product is built to draw. Lower settings and the controller switching the heat on and off use less, so the costs here are an upper limit for the hours you count.

Why are only Sunbeam products in the table?

We list a product only when its maker states the wattage on its own website. Sunbeam does that on every heated bedding page we read. The other brands we checked either publish no wattage on their own site or block automated readers, so we could not confirm a figure.
