9 Best Wall Heaters For Bathroom Reviews

Heating can be a major concern when it comes to renovating any bedroom or bathroom. Reinstalling the existing HVAC system is next to impossible and very expensive. It means I need to break the ceilings and the walls. So, here comes the electric wall heaters to the rescue. They can be installed anywhere you need them to and their location need not be predetermined.

There are several factors that you need to consider when you are looking for the wall heaters for your bathroom. In the following list, we have mentioned the most important ones to consider to make the best choice.

  • Heating Capacity: The first thing that you need to consider when looking for a wall heater for your bathroom is the heat capacity that it offers. For determining this, you need to look at the British Thermal Unit or BTUs of the heater. The higher or lower BTU which you settle for depends on the size of the bathroom and whether the bathroom is insulated or not.
  • Coverage Area: It is important to look at the area that needs to be heated by the wall heater. The size of the bathroom will majorly factor whether the heater is a hit or a miss. You need to make sure that you are going for a heater that assigns every square foot of area at least 10 watts.
  • Placement: The placement is very crucial and it should be done while keeping three factors in mind. The three factors are sizing, air flow and safety. It is very important to consider the manufacturer’s clearance and those instructions should be followed to perfection.

More details on the features to consider are discussed in the “Buying Guide” given later in the article. To make the job easier, we have discussed the best wall heaters for bathrooms, their notable features, advantages and drawbacks. Check them out for your best choice.

Things to Consider When Looking for the Best Wall Heater for Bathroom

Electric wall heaters are space heaters that just need to be plugged in to heat up the required space. They are recessed inside the wall and provide the required heating. However, there are several things that you need to consider before selecting the ideal wall heater for your bathroom. In the following section, we have listed some important factors which will make the task of selecting the wall heater for your bathroom.

1. Heating Capacity

When talking about the heat capacity of any wall heater, you need to look at the BTU or kWh of the heater. You need to consider both the starting heat generation capacity and the heat that it offers to maintain the temperature. The available BTUs of the in-wall heaters range from 1,200 BTUs to 10,500 BTUs and the required heating capacity or BTU for your use would depend on the size of the bathroom and the things that are present in there. You need to understand that one BTU or British Thermal Unit is the energy required by the heater to heat 1 pound of water by 1 degree. If the bathroom is not insulated, you will need a heater with higher BTUs.

2. Coverage Area

Now, the sizing of the heater decides the area that it will be able to heat properly. A small heater that is installed in a larger space cannot properly heat the bathroom and will leave you feeling cold for most part while a bigger heater for a smaller space will not be able to function properly. So, there is a simple rule which will help you choose the ideal heater for the space that you want to heat. You need to see that each square foot has 10 watts of power so that the area is heated up properly. If you are looking at the BTUs, you need to divide the BTUs by 3.14 and you will get the wattage. Then, you can go for the above-mentioned calculation.

3. Placement

When talking about wall bathroom heaters, it is very crucial as to how you place it. You need to take into account the sizing, air flow and safety, all in mind while installing the product. The manufacturer’s clearance must be considered and you need to place them at the correct distance between the floor and the wall. Keep in mind that the clearances are not recommendations and should be followed particularly. You need to take account of the safety distance and make sure that you do not burn yourself while using the bathroom. If you are not experienced in working with electronic heaters, you can hire a professional electrician for the job.

4. Noise Level

The main contributor to the noise level of the wall heaters are the fans of the heater. The heater also houses moving components and parts which cause tapping and clanging sounds. The noises, however, are a common indication that the heater is working properly. But, when looking for a wall heater, 50 dB is the lowest noise level that is available in the market. You should make sure that the heaters are maintained properly and cleaned regularly to keep the noise in check.

5. Type of Controls

There are usually four major kinds of heating control systems for the wall heaters. The first one is the manual room thermostats that maintains the room temperature by turning the system on and off at regular intervals. They are the most economical and simple functioning devices. The next one on the list is thermostatic radiator valves.

They are directly attached to the top or the bottom of the radiators which enable them to control the room temperature. Then comes the programmable room thermostats which feature built-in timers that enable the thermostat to turn on and off at the scheduled time. The last one is the smart heating controls that allows to manage and schedule the functioning of the thermostats through an app on the phone remotely. These are very easy to use.


Most of the wall heaters work on 120 volts but some of the bigger and the more powerful ones are rated at 240 volts. You need to check the voltage supply at your house and choose the heater accordingly. The size of the heater should be based on the requirements and cater to all things that you need from it.

6. Power (Wattage)

When talking about the power of the wall heater you are purchasing, you must consider the space that you want to heat with the product. The power is measured in watts. There is a simple rule to help you select the wattage that you should go for when selecting the heater. You should select those wattages where 10 watts could cater to 1 square feet. This will enable the heater to provide the required amount of heating.

7. Type of Heater

There are two types of heater when we talk about electric wall heaters. The first one is the in-wall heater which is hard wired and recessed in the wall. They feature a thermostat that is fitted on the device or on the wall. They have two voltage rated versions and can feature 120V rating or 240V rating. The second type is the space heater. It plugs into the wall outlet and stands on the floor. They feature the thermostat only on the device and can run on 120V only.

8. Warranty

A wall heater for the bathroom must be maintained regularly to ensure its proper functioning and less noise production. Therefore, investing in an annual maintenance plan is a good idea. Some brands offer free maintenance services during the warranty period. The warranty period also works as a testament for the durability and longevity of the wall heater, so go for those with a higher warranty period. One more thing to consider here is the pricing of the extended warranty period to enjoy the same benefits for a longer period of time.
