How to Pick the Perfect Size Space Heater for your Room

Using the best space heater for 500 square feet garage

Finding the perfect size of a space heater for your room can help you experience a comfortable environment and minimize the costs of heating the house.

Using small heaters will force you to either get additional ones or keep the device on for very long periods. This usually translates into huge electricity bills. Here is a simple guide for picking the perfect-sized heater for your room.

Determine the Size of your Room

The size of the room in square feet is an important value that you can use to determine the right size of a heater to use.  The value is the product of the length and width in feet.

Measure the length and width of your room and multiply the values to get the area. If the length and width of your room are 12 feet by 12 feet, then the area of the room is 144 square feet.

Calculate the Wattage

It is important to determine the heating requirements of your room in terms of wattage. The rule of thumb is that 1 square feet space requires 10w of power.

The wattage requirements of the space heater can be determined by multiplying the area with the number 10. If the area of your room is 144 square feet, then its wattage requirement is 1,440w.

This means that you should go for heaters that are at least 1,440w. In practice, electric heaters come with 1,500w and an option of operating at 750w.

Determine the Height of the Ceiling

If your ceiling is the standard 8 feet high, then you do not need extra heat to maintain the temperature within the living zone of the space within the required levels.

However, if the ceiling is higher than 8 feet, then you need to factor in the amount of energy required to heat the extra space.

A standard rule is that you need an additional 25% wattage to heat every additional 2 feet space. If you have determined the wattage requirements of your room (by multiplying the width and length with 10) as 1,000w and realize that the ceiling is 10 feet high, then you should factor in the additional space. The total wattage requirements of the room would be 1,000w plus 250w.


How well a room is insulated affects the amount of heat energy that is needed to keep the living space warm. For rooms that have standard insulation, you do need to consider adjusting the heating requirements.

However, if a room has a faulty opening that lets in lots of cold air currents, then it would be wise to increase the wattage requirements by 20%. Conversely, reduce the wattage requirements by 20% if your room is heavily insulated.

The Prevailing Temperature

The prevailing weather condition directly influence the heating requirements of your room. In turn, you should factor them when determining the amount of wattage required to keep the home warm.

If you live in areas that are generally cold (average temperatures lower than 32 degrees Fahrenheit, then it is advisable to use the factor of 15 instead of 10 when determining the heating requirements of the room.

If you factor in all these issues, it is straightforward to determine the accurate wattage needs of your room. You can then simply look for a heater with matching wattage.

Which Type of Heater Do I Need for my Home?

Getting the right type of heater for your home is necessary to enjoy a comfortable environment. However, there are many types of heaters available on the market. All of them are suitable for specific purposes because of their features.

To ensure that you do not end up with a heater that is ill-suited for your home, it is important to consider several factors.

Here are a few things that you need to look at when selecting the right type of heater for your home.

Convective Heaters

Convective electric heaters have inbuilt fans that are used to blow the heated air across the room. It takes longer for the fans to effectively distribute the heated air across large indoor spaces. However, once the ambient temperature is achieved, these heaters can successfully maintain it for a long time. Because of the use of the fan, convective heaters are usually louder than the other types of space heaters.

Fuel-Burning Heaters

Fuel-burning heaters utilize natural gas, propane, or even wood to produce heat. If you install a fuel-burning heater in your house, you do not have to worry about the high costs of using electricity to heat the home. However, installing, maintaining, and using fuel-burning heaters are detailed processes.

Moreover, they require a lot of space and, in some cases, modifications of the house. It is because of these reasons that fuel-burning heaters are not commonly used to provide heat in small indoor spaces.

Radiant Heaters

Radiant space heaters produce infrared radiation to directly warm objects within a room. The heated objects in turn warm the air within the living zone of a room. As a result, a comfortable environment is created quickly and maintained as long as the heater is on.

Some radiant heaters have additional features, including a blower and a motor for the oscillation of the heating element. The oscillation of the heating element ensures even distribution of heat within a room in which the heater is placed.

Oil Filled Heaters

Oil filled space heaters operate by transferring heat energy to oil. The oil, which functions as the filler, dissipates the accumulated heat for a long time. This happens because oil can effectively soak up a lot of heat energy and then release it slowly.

Radiant Floor Heaters

Radiant floor heaters have a system of pipes and either an electric heating element or a fluid such as water. For steam heaters, the water is heated to produce steam. The hot steam is then channeled through the pipe network to increase the surface area of the air that is warmed. Electric radiator heaters have a heating element embedded in the pipe network.

Factors to Consider when Buying a 500 Sq Ft Heater


A thermostat helps you to personalize the performance of your space heater. Once you select the ideal heating temperature, your space heater will maintain it automatically. Always go for electric heaters that have inbuilt digital thermostats. It is easy to adapt their performance to the heating requirements of your indoor space.


Timers in heaters help users to determine when the heater should be on or off. It is easier to use and personalize heaters that have timers than those which do not have this feature. You can program your heater to turn on a certain time (mostly up to 12 hours) to maintain a cozy environment at home.


Go for heaters that have adjustable louvers. The adjustable louvers can be used to direct the direction in which heated air is released. Thus, you can adjust the louvers to ensure effective zonal heating at home. This minimizes the overall costs of keeping your indoor space warm because it eliminates cold spots.

Safety Features

Go for heaters that have advanced safety features, including cool-to-touch, tip-protection, and overheat protection. The tip protection feature prevents the occurrence of fires by automatically triggering the heater to shut off if it is knocked down. The cool-to-touch feature helps to keep the surface of the heater cool so that anyone who touches it does not get burned. The automatic shut-off feature protects the heater against the effects of overheating.

Aesthetic Value

Because electric heaters are usually very prominent when positioned in indoor spaces, it is necessary to think about their effect on your general indoor décor. Go for heaters whose colors, design, and finish matches with your interior décor style.

You can also decide to use an electric heater as a focal point in your room. This requires one to carefully consider the design of the heater and type of furniture in the house.

Where to Place a Space Heater

Where to place a 500 sq ft heaterWhere you place your heater depends on several factors, including the type of the device, availability of children at home, and the size of the room. Also, personal preferences determine where a heater can be placed.

On the Wall

Wall-mountable heaters come with all the hardware that you need to install them on the wall. Mounting such heaters on the wall is easy and straightforward. Moreover, the heaters are lighter than those which are designed to be used on the ground. Some electric heaters can either be mounted on the wall or used as free-standing ones.

Standing on the Floor

Free-standing and portable heaters can be placed anywhere in the room where there is enough space. The bases of free-standing heaters are strong enough to keep the devices stable. The main challenge of placing your heater on the floor is that kids and pets can easily access it.

Also, it is easy for a heater that is standing on the floor to get knocked down by accident. Luckily, many electric heaters that can be placed on the floor have the tip-protection feature to prevent the occurrence of fires if the heater accidentally falls.

On Tables, Desktops or any Other Raised, Flat Surface

Heaters that are designed to placed on tables are light and easy to carry from one place to another. Placing such heaters on the table helps to keep them out of the reach of children and pets.
