Bathroom Wall Heater Buying Guide

Bathroom Wall Heater Buying GuideHere are some important things to consider when shopping around for your first or next bathroom wall heater.


Bathroom wall heaters come in all shapes and sizes. It is advisable that before ordering a bathroom wall heater you got to know where you’re going to mount it and the amount space that you have in your bathroom.

How much space can it occupy given that it’s just going to be installed on your bathroom wall? Not much but there’s more to it. The shape, size, or the design of your bathroom wall heater is going to determine your options as to where you can place it.

Take note that the efficiency of your heater will be affected by its placement in your bathroom. We’re going to talk about this topic more in a later section.

Bathroom wall heaters can be a square, rectangle, or can be 50 inches long, so there’s a lot to consider here. If the product that you like comes in a sleek and stylish design then that’s just icing on the cake.

If the design that you’ll choose fits well on the dynamics of your bathroom then everything else will follow, you’re off to a great start.

Heater Technology

Bathroom wall heaters operate on a multitude of heater technology. Infrared, fan-forced, convection or radiant heating technology are your choices. There are advantages to each type and don’t worry because there are hybrids, as a matter of fact, most heaters nowadays are.

If you’re not familiar with the terms then just take note that convection heaters heats air and then transfers that heat onto other objects like people. Radiant technology, on the other hand, works by emitting infrared radiation which flows freely until it is impeded by another object.

Convection heaters rely on the movement of the air that’s why the heat is often fan-forced. Radiant heat is more direct that’s why you’ll feel its effects quickly compared to convection heaters.

Also, take a look at the Voltage range that a bathroom wall heater will work with. Some models work with multiple voltages.


Look for labels on whether a bathroom wall heater is energy efficient. Some use 30% less energy than others, some offer more savings. Most of the time, units with adjustable thermostat where you can control the level of heat are more energy efficient.

You’d usually find a green logo or icon on units that are certified energy efficient.

As we mentioned up top, the placement of your unit will greatly affect its efficiency too. These bathroom heaters in general will heat-up your bathrooms fast, but they can also use up a lot of energy. Be mindful of what you choose and how you use it.

Energy usage and heating capacity should go hand-in-hand when determining a unit’s efficiency. (Capacity will be discussed below).

Ease of Use, Installation and Maintenance

Easy and straightforward controls, readable display, and Wi-Fi controllability should allow you to easily use a bathroom wall heater. Installing these units will be a breeze and maintaining them has very little to no hassle too.

Just make sure that the unit caters you enough in terms of display, controls, light indicators, or ergonomically. You should also consider its weight and components like the fan for noise considerations. Of course, noiseless ones are ideal.

When it comes to maintenance, look at units with a good filtration system. And it is highly recommended that you install an exhaust fan if you’re going to use a bathroom heater.

Wi-Fi connectivity is a good add-on feature to have as it will allow you to control your bathroom wall heater remotely. Share it with everyone in the household and utilize modern technology like your smartphone, or maybe even Amazon Echo and Google Home.

Also, be wary of the thermostat, if your unit comes with an adjustable one then make sure to situate it on your bathroom appropriately.

Safety and other Features

Safety features on a heater sometimes make or breaks a consumer’s decision. And so should also be the case for you when you shop around for one.

Cool to touch feature should be the first thing to consider. Also, only purchase a unit that does not have any exposed heating component. That should be the case for most if not all models nowadays.

You should also consider overheat protection features, maybe an auto-shutoff feature. Anti-trip technology and child lock features will also come handy.

Lastly, consider units that have certification from leading organizations such as ETL, UL and CSA. This will ensure that the unit that you are buying has gone through the necessary tests needed before it is proven safe for the public. A unit that has a large temperature range is also quite desirable.

Brand and Price

Is there a brand that you already trust when it comes to home appliances? Bathroom wall heaters as you’ve read above will have tons of features. While some features are available to most there is also a lot more that aren’t available to other units or brands.

And that would make a difference in terms of pricing. The bathroom wall heater’s price tag varies significantly. Knowing what to look for and comparing it to what you need in your place would sometimes result in a good amount of savings.

How to calculate the right wattage for your bathroom

In this section, we shall explain how the heating capacity of your bathroom wall heater works. This is to help you determine how much the power of the unit that you’ll choose should have.

The best thing to remember when choosing the right power for your bathroom is that 10 watts is usually enough for a square foot. So say, for example, a unit has 1000 Watts then divide that by 10, then you know more or less than this unit is good for 100 square feet of space.

Wattage Square Feet
500 50
750 75
1000 100
1500 150
1800 180
2000 200
4000 400
4800 480

Bathroom wall heaters or heaters in general will have a minimum and maximum wattage. So don’t get confused if you see these on a unit’s specifications.

Also, a heater’s capacity is presented in BTUs. If you can’t find the wattage then just take note that 1 watt is equivalent to 3.41 BTUs. So a unit with 5118 BTUs can be divided by 3.41 and will be equivalent to 1500 watts and that’s good for 150 square feet.

You can also measure your bathroom beforehand and multiple the square foot measurement you got by 10 and you’ll know how much wattage the unit you will buy should have.

A few other things to take note is that infrared heaters will heat-up wider spaces fast. If your bathroom has poor insulation then use 12 watts instead of 10 in the equation.

Safety, Installation and Maintenance

Safety And Maintenance of Ventless Propane HeatersAs always we need to be careful when trying to set up a device, especially in a delicate place like a bathroom. Slipping, falling, and other accidents like electrocution might happen (knock on wood) if we aren’t careful enough.

Here are some safety tips when it comes to bathroom wall heaters.

  • It may be common sense but we need to point it out. Only install wall heaters that are meant for bathrooms! Including your portable heaters, you need to make sure that they work or are meant for damp environments. You don’t want to risk fire or electrocution.
  • Bathroom wall heaters are mostly waterproof but that’s to say that you risk for it to get wet all the time. Make sure to install them on a spot where it won’t get significant splashes of water all the time, or maybe none at all.
  • Also, be wary of pipes that may leak onto it. Or maybe a spot that is directly on top of your shower where there will be most likely lots of steam. As much as possible, install your bathroom wall heater onto a place where it’s unreachable by children.
  • Maybe not specifically for bathroom wall heaters or heaters in general but we’ll know that electrical appliances such as these can be fire hazards. It would be best to have a handy fire extinguisher with you at all times. You may never use it, but you never know.
  • Avoid obstructions within the bathroom wall heater’s path. Don’t put a towel on it nor any other bathroom stuff. Make sure it is unencumbered.

Installation and Maintenance Tips

  • Make sure to install it in a place where the flow of warm air won’t be blocked or else it will be useless or even dangerous.
  • Make sure that the bathroom wall heater is in a spot where the air circulation won’t be blocked. Keep it away from other objects and at the same time don’t put it in dead spaces such as behind your door because that again would render it useless.
  • Install your thermostat (if separate) away from the heater as much as possible so that it will be able to do a proper and accurate reading. Heaters with external thermostats are also ideal for spacious bathrooms.
  • Should you choose to hardwire (plug) your bathroom heater then make sure that you plug it in an outlet with the appropriate voltage.
  • When utilizing a bathroom wall heater your bathroom must have proper ventilation. Also, make sure that all electrical wirings (if any) are properly done by a professional. An exhaust fan and a bathroom heater should come hand-in-hand.
  • Mounting bathroom wall heaters should be easy, you don’t have to do something drastic like cutting into your wall. That’s why we specifically mentioned on our buyer’s guide that you consider the shape of your heater before buying it relative to your bathroom.
  • Always check the manufacture’s installation and maintenance instructions. Get a unit with easy to wash filter and parts, consideration for these tiny components would go a long way.
