How To Choose The Most Efficient Electric Heater?
Heating Power
The measuring unit is watts.
There are two solid features affecting the heating power of an electric heater: your room area and the weather where you live. First thing first, room area!
The larger the area, the more powerful the heater; that is the basic rule of thumb. Don’t try to look for the strongest model out there because too powerful a heater compared to the room size just makes you waste more (both money and energy).
Meanwhile, a too weak one will never heat up your room, then what’s the point?
To find out the right heating power of an electric heater, you should measure the area of your room first.
After that, multiply the number by 100 (if you have the room size in square meters) or by 9.3 (if in square feet).
For instance, if your room area is 20’ x 15’, then you should look for an electric heater offering 20 x 15 x 9.3 = 2790 watts of heating power for efficient and comfortable warmth. But this is not exactly true for all cases.
If you’re living in an area with tougher weather in the winter, it is recommended to go for a few more wattage; and vice versa.
Consistent Performance
An efficient electric heater should not only achieve the desired temperature setting but also maintain it during use. Climate control is exactly the feature we’re trying to talk about.
As stated above, the surrounding condition does affect the performance of your heater.
Too cold weather will decrease the warmth of a room, and this handy feature helps prevent that. It detects a change in the temperature of your space then will automatically adjust to raise heat to the preset heating level, keeping it always stable.
On the other hand, climate control features save the heater from running continuously or overheating, which is safer and more efficient to use.
Also, thanks to it, you don’t have to turn the machine on/off manually every 5 minutes.
Timer
Another feature, that we think any efficient electric heater should have, is a timer, which will automatically turn off after a certain time of running, which saves energy and is safe for night use.
The timer function, aside from offering some preset modes, should be customizable for specific needs. It also should be functioned with frost protection so that when your room temperature drops under a certain amount of degrees F, it will automatically turn off to remain the heat.

FAQs
Is 64 degrees warm or cold?
If the temperature is 64 degrees F, it is considered cool.
How can I heat my room cheaply?
From our experience, here are some budget-friendly ways to heat up a room:
- Install solar panels
- Wear warm clothing
- Insulate your attic
- Invest in a smart thermostat
- Buy an efficient electric heater
Is it cheaper to have the heating on low all day?
No, it isn’t. Keeping heat setting one low during the day won’t help lower your monthly electricity bills. Instead, you’re losing it all day. The better way to use your heater is only to have it run when in need.
Is it cheaper to use an electric heater than central heating?
No, it isn’t. For a certain space, using an electric heater is costlier (at least 2 times) than central heating.
Is it cheaper to keep your house at constant temperature?
Yes, it is. As long as you’re using the heater, keeping it running at a solid temperature mode helps save energy and money.
