Review of Pic-a-Watt Electric Wall Heater

A Pic-a-Watt electric wall heater

The Bottom Line

A good way to heat isolated cold areas that are not covered by your existing heating system. But do not rely upon this as your only heating source. It's good for a vacation house, rental, or RV.


  • Easy installation.
  • Relatively quiet.
  • Multiple wattage settings.


  • Limited coverage (up to 180 square feet).
  • "Squirrel cage" blower does not put out.
  • More appropriate for an RV.


  • Multiple wattage settings to suit your needs: 500, 750, 1000, 1250, 1500, 1750, or 2250. You need to pick a watt. Get it?
  • Cover isolated cold spots.
  • A step up from stand-alone electric heaters.
  • Installs easily, no special tools needed.
  • Existing power inside wall is required. It is hard-wired; there is no plug.
  • Can be controlled by a central thermostat.
  • It installs nearly flush with the wall.


The electrician said it was a "Pic-a-Watt Electric Wall Heater," and I did not quite understand what he meant until I read the box. Sure enough, you can pick your wattage with this electric wall heater, so that you can calibrate your heating in different rooms of the house.

Many of the downsides of this King Electric product apply more to the general category of electric wall heaters than to this one. Electric wall heaters for your house...? Well, even King suggests this heater may be more appropriate for an RV, boat, or trailer, than for a house.

Alas, it is not always possible to spend a fortune on installing a complete forced-air HVAC system in your house, so you do need to find a stop-gap measure (electric baseboard heaters are a good option).

Because electric wall heaters install inside the wall, that is another layer of work you need to deal with. Also, they simply don't put out much heat. It would be near suicidal to rely on a system of electric wall heaters to heat your entire house.

But it's the "pick a wattage" aspect that pushes this electric heater to the top. It allows you to calibrate different heaters to different rooms of your house. It's a recommended buy if you're looking for this type of thing.
