Wall Heaters

When choosing a heating system, you should consider the size of the space you want to heat. If you are looking to warm a small single room, a wall mounted heater can be a good option. In this post, we discuss wall mounted heaters, how they work, how their energy efficiency is measured, their benefits and costs. 

What is a wall mounted heater?

A wall heater is a heating unit that is installed in or attached directly to a wall. Designed to save valuable floor space, they are usually used to heat smaller offices, single rooms or compact living spaces. By installing these units, you will not have to expand the HVAC system you are currently using.

During installation, wall mounted heaters are attached to the wall and wired directly to a circuit in the electrical panel. As such, they are different from portable space heaters that are usually plugged into a wall outlet. With wall heaters, there are no wires to trip on. Since the heaters are self-contained, you don’t have to worry about the costly and time-consuming exercise of installing ductwork.

Types of wall mounted heaters

There are two main types of wall mounted heaters: gas wall heaters and electric wall heaters. Whether you are building a new home or replacing your existing system, it’s important to know which type of fuel works best and costs less.  

  • Gas wall heaters: Large and complex, these heaters require professional installation. While they cost more to buy, they are more affordable to operate. With regular maintenance, gas heaters have a lifespan of 10 to 20 years, which is shorter than that of electric heaters. One of the downsides is the potential leak of carbon monoxide, a poisonous gas that can be fatal.
  •  Electric wall heaters: Compared to gas wall heaters, electric heaters have a lower initial purchase price but are more expensive to operate month by month. The units are quiet and durable, with an average life expectancy of 20 to 30 years. They are also easier to maintain and do not combust fuel onsite, eliminating the risk of carbon monoxide or gas leaks.

Wall mounted heater energy efficiency

Energy efficiency is one of the critical factors that people consider when choosing a wall mounted heater. As such, it is important to understand how the energy efficiency of the units is measured.

The energy efficiency of a wall mounted heater is measured using the Annual Fuel Utilization Efficiency ratio or AFUE standard. It is calculated by dividing the amount of fuel supplied to the heater by the amount of heat produced by the device and expressed as a percentage. Generally, heaters with a higher AFUE rating are more energy efficient. Because they use up less energy to keep your space warm, the operating costs are lower. Wall mounted heaters with AFUE ratings of between 80 and 85 percent are considered to be of mid-efficiency while those with ratings above 90 percent are said to be highly efficient.

Benefits of a wall mounted heater

Choosing a wall mounted heater brings numerous benefits. Here are some reasons to consider installing one of these units.

Fast and efficient heating

Provided the unit is operated with proper safety precautions, it can heat your space in a few minutes. By warming only specific areas, wall heaters consume less energy and run more efficiently.

Save space

Apart from their compact size, the heaters are attached directly to your wall. This frees up your floor space as well as your window, making them ideal for those living or working in smaller spaces.

Lowering your heating costs

For a good number of people, the cost of heating their homes goes up when the temperature drops. Wall mounted heaters are energy efficient, providing a modern and unique way to bring down your energy costs. Instead of heating your home, these cost-effective units allow you to warm up only the area you are currently residing in.

Easy to install and maintain

Wall mounted heaters are very easy to install, with a good number of people doing the job themselves. Unlike central heating systems, no major ongoing maintenance is necessary. If something does need to be repaired, these units are relatively easy for a repair professional to access, uninstall and reinstall. 

Innovative features

Some of the more advanced features include precise thermostats, remote controls and Wi-Fi controls. Units with precise temperature controls have digital displays and sensitive thermal sensors. These features help you to control temperature accurately for optimal comfort and use less energy to heat your space. With these units, heating your home does not have to be a headache.

Wall mounted heater costs

The price for a wall mounted heater will depend on several factors including the unit’s power, energy efficiency and any special features. Cost is also influenced by the brand and specific model you choose. Generally, a wall heater will cost between $450 and $550. If you choose to have it installed professionally, expect to pay an additional $150 and $200 in labor costs alone. When you request a quote, ask for an itemized list of what the job includes. You might be able to save a bit by providing the installation materials yourself. In terms of operating costs, expenses will be different depending on whether you have a gas or electric wall heater.


Are wall heaters dangerous?

With proper maintenance and the right safety precautions, wall heaters are quite safe. Ensuring your gas wall mounted heater is in perfect shape will reduce the chances of gas leaks. Leaving reasonable space around your electric wall heater will help to lower the risk of fire caused by heated coils.

How do wall heaters work?

Wall heaters have a relatively simple working mechanism. The units consist of a heating element that converts energy from the fuel source into heat. The wall unit then expels that warm air into your space.
