4 Best Wall Mounted Electric Heaters In 2021 (Energy Efficient; Under $0.30/h)

Wall-mounted electric heaters are becoming increasingly popular. They offer an easy-to-use and energy-efficient way to heat up even a larger room (to about 500 sq ft).

Now, there are 100s of wall electric heaters on the market today. Which are the best wall-mounted electric heaters? Which energy-efficient electric heaters can be wall-mounted? We cracked open the specification sheets of the best-selling wall electric heaters to figure out which ones are the best.

Here’s what we found about electric wall heaters:

Homeowners love them because they are not there somewhere on the floor. You cannot flip them over and accidentally start a fire (very safe), you can mount them higher enough so your kids won’t be able to reach them, and they are, above all, convenient. Just mount it on the wall and turn ‘on’ for heating.

We also need to be aware of energy efficiency. The most energy-efficient wall heaters can reach 99% efficiency. That means that 99% of input electrical energy is transformed into heat.

Example: 1,500W wall-mounted electric heaters are the most common ones. Here’s how energy efficiency works; we deliver 1,500W input (usually 12.5 amps at 120V voltage), and an efficient wall-mounted electric heater can use 99% of that. That means that we get about 1,485W or 5,071 BTU of heating output.

How much does it cost to run a 1,500 wall-mounted electric heater?

Well, if you run it at 100%, it will burn through 1.5 kWh every hour. If you use the national average price of electricity ($0.1319 per kWh), that’s about $0.20 per hour.

Another specification you should be aware of is the heating method. You can choose between forced air, radiant, and convection heating. Forced air is usually preferred because it improved indoor air circulation in addition to providing indoor heating.

If you look for the best and most energy-efficient wall-mounted electric heaters based on specifications, you will likely come up with a list of 4 superb units. We’ve done exactly that and made a list of the 4 best wall electric heaters, complete with the spec-by-spec comparison table and individual reviews (found further on).

Stiebel Eltron is the most well-known producer of wall-mounted electric heaters. This is the German company best known for their electric tankless heaters; those are quite complex to engineer. Wall electric heaters are easy for Stiebel Eltron; their best model is the Stiebel Eltron 074058.

It’s a standard 1,500W electric heater that can be mounted on the wall. It has a surface-mount design. That means that you don’t have to create a recess to mount it on the wall.

This heater is made out of galvanized steel and a squirrel cage-type blower. The heating method is forced air. Even when producing and outputting more than 5,000 BTU/h of heat, the Stiebel Eltron 074058 runs at very low decibel levels (49.7 dB, to be exact). It’s one of the quietest wall-mounted electric heaters on the market.

It has a number of key features that make it much more convenient to use. These include an even-heating down-draft design (it sucks in the cold air at the top and blows out heated air at the bottom), a booster timer (it produces 100% capacity output for 1 hour; for quick room heating), and it also has a frost protection setting.

On top of that, it’s one of the most energy-efficient wall electronic heaters. When running at 100% output, its running costs are about $0.20 per hour. Even more important, this is a wall-mounted electric heater with a thermostat; the thermostat will reduce the output and thereby costs when the set temperature is achieved. This makes the Stiebel Eltron 074058 that more energy-efficient than comparable wall heaters.

All in all, Stiebel Eltron 074058 is the best wall-mounted electric wall heater made by the best German company in the industry. It’s energy-efficient, quiet, reliable, and packed with key features for convenience:

For bigger rooms, you will need a bigger wall-mounted electric heater. Most wall electric heaters run on 1,500W; that’s the standard wattage. There is a limited number of bigger units. Out of those, the KING PAW2422-W is the best large room wall-mounted electric heaters.

KING PAW2422-W runs on 2,250W; that’s quite an increase compared to the 1,500W heaters. That’s why it has a larger coverage area; up to 770 sq ft, to be exact. With the forced air heating method, it can adequately circulate the hot air across larger rooms.

At the maximum wattage, the KING PAW2422-W costs about $0.30/h worth of electricity to run. That’s why it’s important that you can adjust the heating output (and lower running costs) when a large room gets warm enough. It doesn’t come with a thermostat. Instead, this is the Pic-A-Watt electric heater for the wall. Basically, you can pick the wattage and thereby control both the heating output and the electricity costs.

The squirrel cage blower is very quiet. However, this electric heater needs to be hard-wired into the wall; it’s not a plug-in model. That makes it less popular.

All in all, if you need a wall-mounted electric heater for larger rooms, you have to look for units with 2,000+ watt input. KING PAW2422-W is the best choice because it runs on 2,250W and it can produce more than 7,500 BTU of heating output:

KING PAW2422-W Review

Pros
  • Best for bigger rooms; it has an up to 770 sq ft specified room coverage
  • Runs on 2,250W and produces 7,500 BTU of heating output (compared to standard 1,500W units)
  • Uses Pic-A-Watt principle to lower the output when needed (and lowers costs)
Cons
  • Doesn’t have a thermostat; it’s replaced by the Pic-A-Watt principle
  • Needs to be hard-wired; not a plug-in model

EconoHome Heater is an energy-efficient wall-mounted space heater. Even when running at 100% heating output, it costs only 8 cents per hour (using average national electricity price of $0.1319/kWh for calculation). However, the lower running costs also mean that the heating output is lower.

Compared to the standard 1,500W wall heaters, the EconoHome Heater top wattage is 600W. That means it is only adequate to heat spaces up to 200 sq ft. Nonetheless, if you need a wall-mounted electric heater for small rooms, you don’t need anything bigger than the EconoHome Heater.

The heating method is convection. It doesn’t blow hot air or radiate heat; instead, the EconoHome Heater heats up the air that is in its vicinity.

This is a plug-in model; doesn’t require hard-wiring. You just plug in it 120V, and press ‘On’.

Coupled with energy efficiency, the ease of use makes it one of the most popular efficient wall-mounted electric heaters
