What Is An Infrared Bathroom Heater?

Infrared bathroom heaters work by heating objects, walls, floors, and people in a space using infrared light, instead of heating the air. They are extremely efficient and cost less to operate than a fan-based electric space heater. In many instances, the infrared bathroom heater may be almost invisible. They are often sold as a white ceiling fixture, a glass panel that holds your towel rack, or it can hide behind a big mirror over the vanity. This means they take up no additional wall or floor space.

Many infrared bathroom heaters are sold with an electrical plug, which allows you to mount it to the wall and just plug it in. However, that will be your only control for the heater unless you have a Part P certified electrician hardwire it to an existing circuit. That will be an added cost, but it lets you set up a wall switch or connect it to a thermostat. Compared to the fuss needed to add a radiator in the bathroom that connects to your main heating system, it is a fast and affordable option.

Benefits And Features Of An Infrared Heater

Since these heating panels look so sleek and modern, many manufacturers are now adding Wi-Fi and Bluetooth capability to their control units. Look for a model able to be controlled by your smartphone and integrated with your wireless thermostats.

One of the huge benefits of an infrared heater for a bathroom is that it warms all the surfaces in the room, including the floor and the tub. You will not experience that shock of stepping into a cold bath or stepping out onto cool tiles. Even if you have drafts around the window and door, that will not immediately cool off the warm floor and walls.

Another perk is if you have a heater that doubles as a mirror, it will almost never fog over during a steamy shower. The mirror will melt away the moisture as soon as you shut off the water. Since the walls and floors are also warm, it fights off the buildup of mould and mildew on surfaces in a bathroom.

It does take a little time for the heater to warm up all the surfaces in a cold room. You may wish to put your heater on a schedule so that it warms up the bathroom an hour before morning showers or before bedtime.

Some people that like the feel of warm air on their skin, like what a fan-based electric heater produces, and will comment that they feel chilly with the infrared heater. That is because it does not heat the air.  The air eventually absorbs the heat from the walls, floors, and fixtures. You may want to set the temperature for the bathroom a few degrees higher than the rest of the house for this reason.

How Much Does An Infrared Heater Cost?

A typical infrared heater sized for your medium-sized bathroom will run between £180 to £400 for the heating unit. Depending on existing wiring, you can expect to pay a certified electrician between £300 to £600 to have it hardwired into your home.

Are Infrared Heaters Safe?

Yes, they are a safe option for heating a small room like a bathroom. The unit will get hot to the touch. But, since the panel is typically wall or ceiling mounted, it is out of reach of small hands. Read the label of the unit and look for CE certification. It is constructed with an automatic shut-off switch, so if the unit ever malfunctions, it turns off before a fire starts. Finally, infrared rays are completely safe. You can install this unit totally confident that it is safe for your family.
