Save Money with the Most Efficient Space Heater Ever!

Electric space heaters are the most efficient type of heater available. The amount of energy used equals the amount of heat the space heater puts out. Electrical energy converts to heat so there is no waste. All you have to do is size the room you want to heat and choose an electrical space heater that can heat the square footage desired.

The following options are allenergy efficient for one reason or another. Features vary, but each heaterprovides efficient warmth.

1. Convection

A convection heater heats up slowly, but once warm quietly emits enough heat into the room to keep it consistently comfortable. Many convection heaters are shaped like a traditional radiator heater and are filled with oil warmed by electricity. This heating method retains warmth longer than other types of space heaters and provides even heat distribution.

A convection heater is good for longer heating periods as it has a relatively high thermal mass. A heater like this takes a while to warm up, but the room stays heated longer, even after you shut the heater off.


2. Combination fan-forced

Combination fan-forced heaters are quick and powerful. A built-in ventilator blows air over heated metal coils or ceramic plates, which in turn heats the room.

A fan-forced heater is slightly noisier than other types of heaters, and because the fan is the heat generator, it cools off faster when it shuts off.

3. Radiant or Quartz

Radiant heaters warm objects rather than the air. Radiant heat is a unique transfer of energy that naturally searches out colder objects to warm. Electromagnetic energy transfers through a conductive material to create resistance or heat.

Instead of rising like warm air, radiant heat starts by warming the coldest and closest objects from its source.

Each form of heating described above has its own level of efficiency. Specialized features can make them even more cost effective. The table below depicts different types of heaters and basic energy-saving features.

Common questions posited by consumers concerning efficiency are:

  • How much space does it heat?
  • How many energy does it draw?
  • Does it have energy saving features?

The features shown in the table above are all great energy-savers.

A built-in thermostat monitors room temperature, automatic shut off turns the heater off when the room temperature is met, and the timer allows you to use the heater only when needed.

All of these features help keep energy costs down.

Consumer consensus indicates the NewAir AH-450 oil filled radiator and the QMark HBB750 hydronic baseboard heater are by far more effective that other heaters.

In terms of efficiency, they produce long-lasting warmth that doesn't dissipate easily. In other words, you can run the heater less and stay warm longer.

Rated effective in matters of efficiency is also the DeLonghi TCH7690ER ceramic heater. This option heats personal spaces quickly, and because it includes ceramic plates instead of a metal coil, it retains warmth a little longer. Similar in design but using a metal coil as a heat element is the QMark 2544W traditional baseboard heater.

Depending on your needs, a low profile convection baseboard heater like the NewAir AH-600 or quartz tabletop heater like the Soleus MS-09 is effective. If you want one with a fan, consider the Dr. Heater DR-968. Reviews indicate this unit "performs as advertised" meaning it heats large rooms in a cost effective way.


How much energy do these heaters draw? On average, each of these heaters uses about 1500 watts of energy. What your utility company charges for energy use will determine the cost.

The way to calculate the cost of an electric heater is as follows:

1. Find out how much you pay per unit of electricity. This information is on your electric bill.

2. Find out how much input power the heater uses in kW. This is usually marked on the packaging or the side of the heater.

3. To estimate hourly running cost, multiply the input power in kW by the price of your electricity per kW hour. For example, if you pay 7.53 cents per kWh and you run a 5,000 watt or 5kW heater you would multiply 7.53 cents/kWh x 5kW x 1 hour = 37.65 cents per hour to run the heater.

4. To estimate daily running cost, multiply the cost per hour by the number of hours you use the heater.

5. To estimate your yearly running cost, multiply the daily cost by the typical number of days you plan to use the heater.

To further increase efficiency, simply add insulation to a room that's not already insulated, use rugs on hard floors to add warmth, and add weather stripping to doors and windows. This will help you get the most of your space heater.
