Choosing The Correct Heater Size For Your Home

While buying the best energy-efficient space heaters, it is vital to know what size to buy. That is why we have listed a few important pointers, one by one. Following them will help you choose the correct heater size for your home or office use.

Measuring Your Space

The first step to follow is to measure your room or any space where you are planning to install your heater. The large space will require a heater with more heating capacity. Whereas for small rooms, you can even go with models having less coverage area. If you are buying for a room measuring 10 by 10-foot, prefer space heaters of the coverage area of around 100 square feet.

Calculate Wattage and BTU Needs

After deciding on the right coverage area of your selected model, now determine the right wattage and BTU (British Thermal Units) needs. The thumb-rule formula to calculate this is to multiply each square foot of area by 10 watts. So, a heater covering 100 square feet area should come in 1,000 watts of power.

Moreover, to calculate BTU, multiply each watt by 3.41. This is because one watt of electricity can lead to 3.41 BTUs. You can easily find these details in the product description section of any space heater. Therefore, make sure you check these values carefully and opt for the suitable ones only.

Evaluating Room Features

Now, consider your room's existing features to select the right model. For example, if your room already has large furniture units or other décor items, look for heaters with more heating capacity. This is also the case with offices or other commercial places, where the frequent opening of doors is common.

Along with this, you also need to consider the insulation of your room. Highly insulated rooms stay warm. But with rooms that lack insulation, go with heaters that can provide sufficient warmth despite all odds.

Accounting for Safety

Safety is one of the most important factors that one must consider while buying space heaters. This is because you don't want your heaters to over-burn or lead to unfortunate home fires. Well, yes! Many heaters that don't possess the right safety features can cause a real safety hazard.

That is why looking for safety features like auto-turnoff mechanisms and overheating prevention settings is imperative. Few available models also feature an in-build thermostat and are energy efficient too.

Choosing a Correctly Sized Model

Finally, you have reached the pointer, where you are ready to finalize your heater size. Make sure you consider all the mentioned above factors carefully. In the market, there various popular brands that produce all-sized space heaters. They also provide a detailed size chart for their customer reference. Therefore, you can buy any size that best matches your heating requirements.


When shopping for a new heater, you're probably looking for something that will keep you warm without disturbing the peace. That’s why it’s important to do your research before purchasing a heater. While some advertisements claim their units as quiet, there’s no guarantee they’ll be quiet enough to keep you from being bothered.

Moreover, you should consider the heat your selected model generates and the noise level of your device. Some factors affect this, such as the design of the device, the heating element, and the fan. In general, the more powerful the heater, the higher the noise level.


A space heater can be a significant investment if you need to keep your home warm. Space heaters come in many types. They can be electric, oil, gas, or propane. But energy-efficient heaters are the best choice, not just because of their convenient usage but also because they are cost-effective.
