How we compare

Last updated: October 3, 2026

ComfortRated compares compact home heaters so you can choose the right one for your room without digging through a dozen sales pages. Here is exactly how we do it.

What we compare

• Power (watts): the most honest indicator of how much heat a heater can produce.
• Stated heating area: shown as the manufacturer states it, next to our 10-watt-per-square-foot rule of thumb so you can judge it.
• Safety features: listed only when the seller states them (tip-over switch, overheat protection, certifications).
• Weight, size, plug and voltage: so you know it fits your space and your outlets.
• Shipping countries and delivery times: shown for every model.
• Return policy: summarized in plain language from the seller's own terms, including who pays return shipping.
• Price: checked for a single unit and dated.

Where the information comes from

Specs, policies and prices come from each seller's product page and policy pages. When we buy and test a unit ourselves, we say so and add our own photos, measurements and video. CONFERIR

How the spec score works

Each heater gets a score from 0 to 10 in six areas, based only on what the seller states. The spec score is the average.

• Heating power: stated wattage (higher wattage = more room-heating ability; "not stated" scores low).
• Safety features: tip-over shut-off, overheat protection, auto shut-off and recognized certifications.
• Controls: thermostat, timer, remote.
• Return policy: length of the guarantee and who pays return shipping.
• Transparency: how completely the seller publishes specs (power, size, weight, voltage).
• Portability: size and weight for moving it between rooms.

The score compares specs on paper. It is not a lab test, and we update it when sellers change their specs or when we test a unit ourselves.

What we don't do

• We don't repeat claims we can't support, like "heats your whole house" or "cuts your bill in half".
• We don't invent star ratings or reviews.
• We don't sell products ourselves. Purchases, shipping and returns are handled by the seller.
