Indoor Electric Heaters; A Rundown

Indoor Electric Heaters; A Rundown

An indoor electric heater is an electrical device that converts current into heat. It has a heating element, otherwise referred to as an electrical resistor.

Also, an electric resistor works on the principle of Joule heating. However, an electric current passing through a resistor will convert the electrical energy into heat energy.

In most cases, modern electric heating devices make use of nichrome wire as the active element. At the same time, the heating element depicted on the right uses nichrome wire supported by ceramic insulators.

Furthermore, electric heating is a process in which electrical energy is converted to heat energy.

In addition, a space heater is a device used to heat a single, small-sized heater to a medium-sized area. Also, they are powered by electricity or burnable fuel, such as natural gas, propane, fuel oil, or wood pellets.

Portable space heaters are usually electric because you need a permanent exhaust for heaters that burn fuel. Moreover, space heating is used to warm the interiors of buildings.

They are helpful in places where air handling is complex. Also, they are several methods of space heating used.

Indoor Electric Heaters; Types

There are several types of heating elements, and they include:

Convection Heater

In this type of heater, the heating element heats the air using convection current. However, hot air is less dense than cool air; hence, it rises due to buoyancy, allowing more cool air to flow in and take its place.

Also, the convection current of air is set up using the hot air that rises from the heater to heat the surrounding space, cools, and then repeats the cycle.

This type of heater operates silently and has a lower risk of ignition hazards. It occurs when they make unintended contact with furnishings compared to radiant electric heaters.

More so, they are ideally suited for heating a closed space.

Infrared Radiant Heaters

An electric infrared radiant heat uses heating elements that reach a high temperature. This element emits infrared radiation that travels through air or space until it hits an absorbing surface and then partially converts it to heat and reflects partly.

However, this heat warms people and objects in the room instead of warming the air. Therefore, this type of heater is advantageous in areas with unheated air flows.

They are ideal for basements and garages where spot heating is desired.

Additionally, radiant heaters operate silently and present the most significant potential danger of ignition in nearby furnishings due to the lack of overheat protection and focused intensity of their output.

Fan Heaters

It is otherwise called a forced convection heater. A forced convection heater is a kind of convection heater that includes an electric fan to speed up the airflow.

Also, it has a moderate risk of ignition hazard if it makes unintended contact with furnishings. Even so, it operates with considerable noise caused by the fan.

More so, this heater heats space faster than other types of heaters. Furthermore, it is more compact than heaters that use natural convection and is cost-effective for portable and small room heating systems.

However, let’s proceed to how you can mount your indoor electric heater.

How To Position Your Indoor Electric Heater

How To Position Your Indoor Electric Heater

There are several ways to place your indoor electric heater, provided it is out of reach of children. However, the positioning is also determined by the requirements of your home.

Hence, you must buy an indoor electric heater that suits your home requirements. Below are the ways you can position your indoor electric heater.


You can place these types of heaters anywhere in the home. However, they are not as light as the wall-mounted types.

However, you can quickly move them from one room to another.

Wall Mounted

You may not know that wall mounted is the type of heater for a home with kids and pets. This is because they are generally smaller and lighter than the conventional ones.

Hence, it is easier to mount on a wall.


This is one of the most convenient heaters if you have to carry your heater around. You can take it to another room if the need be.


Portable heaters can be carried and used anywhere. Whether indoor or outdoor, all you need is an electrical socket.

Indoor Electic Heater; Buying Guide


How much do you budget for the electric heater, or is the budget part of your plan? ItTis the most essential factor to consider when buying an indoor electric heater for a large room.

Also, you must set your budget before going to the store to pick an indoor electric heater.

More so, this will help you stay within range in your choice of picking. However, setting a budget does not limit you to buying an inferior indoor electric heater.

Instead, it helps you stay focused and pick the one with beautiful features within your budget range.

Heater type

Another vital factor to consider is the type of heater you are willing to buy. However, there are three heating technologies under which every electric heater falls.

As earlier highlighted, consider the heating element type you want to buy before purchasing. Therefore, select the appropriate heater for your application as it is the best way to ensure effective performance.

Noise level

The indoor electric heater, just like most electrical appliances, emits some noise during operation. However, some models produce more sound than others.

Hence, it is crucial to consider a non-fan unit such as a baseboard or an oil-filled radiator heater for silent operation in quiet environments.

Radical heaters are suitable for bedrooms and offices because they are silent space heaters.

Heating capacity

Ensure to consider the size of space you want the heater to cover before buying one. The wattage rating of the heater can determine the heating capacity.

Generally, the average capacity for a square foot space is 10 watts. Hence, a typical 1,500-watt heater will cover an average-sized room as large as 150 square feet when used as a supplementary heat source.

However, this does not apply to every model. Some heaters may cover more space depending on heating technology, the application, and the indoor environment.

Safety Features

Portable heaters can become fire hazards if it is not correctly monitored. Therefore, it is essential to consider safety.

Moreover, many manufacturers use cool-to-the-touch surfaces and other advanced safety features to reduce fire risks.

In addition, some heaters have an internal switch that automatically turns off the power, that is, if the heater is knocked down or tipped over accidentally.

Furthermore, most electric heaters have an overheat protection feature. This comes as a switch sensor that automatically shuts the heater if the internal components reach an unsafe temperature.


Here, you must compare efficiency if you are concerned about maintaining low heat costs before choosing an indoor electric heater.

Ensure to choose the right energy-efficient heater for your environment and your space size to avoid skyrocketing electric bills.

In addition, consider some unique features like energy-saving modes, low wattage, adjustable thermostats, and programmable thermostats that will help you minimize power usage and contribute to economic operation.
