Buying Considerations – Space Heaters for Coverage Area from 500 to 1000 Sq. Ft.

After reading the above reviews, you are convinced that the best way to heat 1000 sq ft is to buy a reliable heater. However, the question under discussion is which type of space heater fulfills the heating requirement when the temperature gets too low.

That’s why it’s essential to discuss the types of space heaters available in the market and their comparison.

Common Types of Space Heaters

There are the following two types of space heaters based on the heating mechanism:

Radiant Space Heater

As the name suggests, the radiant heater uses rays, such as infrared, to warm both indoor and outdoor spaces. In addition, it’s an energy-saving heater that ensures silent operation.

However, the downside of the radiant space heater is the fire hazard. That’s why you shouldn’t leave the heater on while sleeping.

The good news is advanced radiant space heater models come with safety features to ensure your safety and protection.

Infrared, halogen, and quartz are the most commonly used electric radiant heaters. However, you can also buy gas-burning radiant heaters that use natural gas, kerosene, or propane.

Convection Space Heater

A convection space heater works on the principle of warming the air around. The heater produces hot air that circulates in the surroundings to warm the room.

For instance, a ceramic heater is one of the most commonly used convection space heaters. Electricity heats the ceramic plates while the fan blows the hot air into the room.

A convection space heater is an apt choice to heat large spaces of up to 1000 square feet efficiently. Not only that, but these space heaters are portable, allowing you to place them anywhere in the room.

On the downside, the convection heaters have louder operations compared to radiant heaters.

Other than ceramic heaters, some convection heaters use water or oil, while some heaters use fuel.

First, you need to ensure that the heater you buy can heat large rooms and spaces from 500 to 1000 square feet. The general rule of thumb is that one square foot requires 10 wattages to warm the space. So it means you need at least 5,000 watts to warm a 500 square feet area. Similarly, a 1,000 watts heater is sufficient for a 1,000 square feet area.

Additionally, you can do some calculations by multiplying the wattage ratings of the space heater by 3.41 to get the thermal heat in BTU. Hence, 5,000 watts multiplied by 3.41 is equivalent to 17,050 BTUs. Therefore, it implies you should buy a space heater that offers 17,050 BTUs of thermal heat to warm 500 square feet.

Rooms with heavy insulation require space heaters of less power to warm them. In such a case, 7.5 watts per square foot will be sufficient instead of ten watts. However, you need more power to warm rooms with no insulation.


Keeping your family warm and safe is your topmost priority while buying a space heater. The good news is many heaters include a shut-off feature that turns off the unit automatically if someone accidentally tips over.

You should also check for the features such as overheat protection and cool-touch surface.


The controls on the space heater’s interface should be user-friendly with straightforward options. Moreover, a touch screen allows people to adjust the target temperature while monitoring the actual room temperature on the LED.

Many space heaters also allow you to set a timer to switch off the heater after the set interval automatically.

Lastly, many people prefer a remote control to adjust the settings without leaving the couch.

Eco Mode

It’s an advanced technology that allows you to save energy by running the heater at lesser power or watts. Many people don’t like the heaters to blow warm air at full speed. So here comes the eco-mode or energy-saving mode into play to minimize your energy cost.


Winters mean reading a book snuggled in a blanket in front of a space heater. However, if you don’t want to shiver in the coming winters, you can buy any of the best heaters for 500 square feet and above, discussed in this review.

A gas or electric heater can help you warm your basement or heat large rooms and spaces from 500 to 1000 square feet. Not only that, but it also helps you save electricity bills, courtesy of its targeted warmth to a specific room.
