How much room will 1,500W heat?

At 1,500W, roughly 5,118 BTU, it suits a small to medium room, around 150 square feet in a well-insulated home. Rooms with poor insulation or open layouts will need more.

Yes. It is a convection heater, so it warms air without a blower fan. You may hear a faint click from the thermostat cycling on and off.

Does it need a special outlet?

It draws 1,500W, about 12.5 amps at 120V, so it should run on a standard 15-amp household circuit. Avoid sharing that circuit with other high-draw appliances.

Can I mount it myself?

It is a wall-mounted unit, so installation means drilling and anchoring it to the wall and routing the cord to an outlet. If you are not comfortable with that, hire an electrician or handyman.

Is $312.04 a good price?

Only one store lists it new at $312.04 as of November 5, 2026, so there is no recent range to judge against. Compare it with other 1,500W wall-mounted convection heaters before deciding.
