The cost worksheet in our free guide walks through every line.

The standard sizing rule is 1 kW of heater power per 45 cubic feet of room volume, plus about 25 percent extra when walls include concrete, tile, or glass. Our sizing calculator does the math for any room dimensions.

Most traditional heaters over 3 kW require a dedicated 240 V circuit sized to the heater power, installed by a licensed electrician. Many compact infrared units run on a standard 120 V outlet. Every listing here shows the published power requirements where the manufacturer provides them.

Operating cost is heater power times session hours times your electricity rate. At the national average residential rate, a 6 kW heater running a 1 hour session costs roughly a dollar. The running cost calculator uses current state rates from the U.S. Energy Information Administration.

Specifications and prices are collected from manufacturer and authorized dealer listings, with the source recorded per model, and electricity rates come from the U.S. Energy Information Administration's monthly state tables. Listings are checked for changes automatically.
