Bathroom ceiling heaters are designed to provide optimal heating and dehumidifying results in bathroom spaces. Many heater designs provide multiple heat settings and automatic starting and stopping functionality so that overheating does not occur. The bathroom stays at a moderate temperature throughout the day.
Proper use of the bathroom ceiling heater fan design can increase the comfort of the room and the entire house due to its ability to decrease mold and material deterioration, in addition to helping you through those cold winters.
A ceiling heater for bathroom spaces often costs no more than a couple hundred dollars at most, providing a beneficial investment made to last.

Recap: Best Bathroom Heaters
Tips for Replacing An Electric Bathroom Heater
You need to replace your bathroom heater because it’s dying, dead or it’s just time for a new heater.
There are 5 things you should do before you start browsing for a new bathroom heater:
1. Were you ever happy with the amount of heat your old unit produced
2. What is the voltage you need
3. What is the wattage you need
4. What is the hole – not the grille – dimension of the unit
Step 1: Were you ever satisfied with the amount of heat the old heater produced
Is your current bathroom heater putting out too much heat or was it not powerful enough to reach your desired temperature?
Now is your the chance to fix this problem with a larger or smaller heater? You’ll want to contact an electrician. An electrician will not only install one for you but will be able to determine what unit will best meet your needs and if you have adequate power to upgrade to a large size wall heater
If you are happy with the current heat output please go to step 2
Step 2: Understanding and know which voltage you need
Understanding voltage: it’s very important that you understand voltage when buying a replacement heater. If you buy and wire a 240-volt heater to a 120-volt circuit you will only get about ¼ or 25% of the heat output/wattage the heater was designed to deliver.
If you wire a 120-volt heater to a 240-volt circuit your heater will overheat and be destroyed! The heater will try to deliver four times its rated wattage, causing the element permanent damage.
So again, it’s VERY IMPORTANT you know your voltage.
Step 2A: Identifying the older heater’s voltage
1. Turn off the power to the heater in the circuit panel or fuse box. Start by shutting off the circuit that services the heater and double-checks for power by using a voltage meter. When you are sure that the power is in the off position,
2. Look at your panel: Is the heater’s circuit breaker a single or double pole breaker? Look at the picture below to tell the difference. A single-pole breaker works with 120 voltage products and a double pole breaker works with 240-volt products. You will also find a number on the actual switch. This number tells you how many amps the breaker can handle.
Single Pole Breaker (120v) Double Pole Breaker (240v) check amps
Step 3: What is the wattage you need?
Go back to where your bathroom heater is located and take the screws off the heater’s front grill or where the electrical connection is. (Do Not Skip Steps One and Two) You’re looking for the nameplate inside the unit for the voltage and wattage of your current heater.
Once you find it you should see the voltage and wattage
Voltage FYI: over the years the power companies have been raising the voltage to your home or office.
o 110 volts, 115 volts, 120 volts, 125 volts
(All four voltages will work with the same heater)
o 220 volts, 230 volts, 240 volts, 250 volts
(All four voltages will work with the same heater)
o 208 volts is NOT the same as 240 volts – it’s a total different voltage
If the nameplate is worn off and you can’t read it, resort to step two which is the breaker size, and if it’s a single or double pole, and the number on the switch, should say, 15, 20, 30, 40, or 50 – the number is about of amps it can handle. Feel free to call us or consult an electrician if you get stuck.
Step 4: Dimensions:
If you are looking to replace your wall heater or ceiling heater or kick space or any other heater that is recessed into the wall and not ripping down the wall due to a remodel job, you are just replacing the heater, then you will want to find a heater that is close in size to the original one.
With the power and the front grille still off measure the hole in your wall and not the grille. The grille can be one to two inches bigger than the hole, so you always want to measure the hole dimensions when looking to replace a bathroom heater that is recessed.
Step 5: If you have a thermostat older than 10 years you may want to consider swapping that out too. Thermostats start to lose temperature accuracy after 5 years
When shopping for an electric bathroom wall heater for a new construction job (not replacing an old heater) there are several things to consider:
1. Heater sizing (how big is the bathroom you want to heat)
How Much Heat Do I Need?
When heating a bathroom, I like to oversize the heater more than I would any other room because you want to get the room up to 75-80 + degrees and you want to do it at a fairly quick rate.
The standard sizing rule of thumb is:
10 watts per sq. ft. Example: if your room is 10 x 10 multiply 10′x 10′= 100 Sq Ft) 100 sq ft. X 10 watts = 1000 Watts. With a bathroom heater, I like to substitute 10 Watts Per Sq Ft with 12-15 watts per sq ft and in colder environments, I use the 15.
Knowing and getting your correct voltage is right up there as one of the most important things to know and understand before you purchase an electric wall heater. Electric bathroom wall heaters come in 120 and 240 volts. Some electric wall heaters only come in 120 volts, and some only come in 240
Most homes in the United States have both 120v and 240v in their house. If you have an electric stove, range, dryer, or water heater in your home those are all running on 240 voltage.
A standard 120-volt wall heater comes in 500 to 1,500 watts which can heat a room 50 to 150 sq. ft. If you have a room bigger than 150 sq. ft. you will need a 240-volt heater.
A standard 240-volt wall heater comes in 1000 to 4,800 watts which can heat a room from 100 to 480 sq. ft.
A common oversite is buying and or installing a wall heater with the wrong voltage. If you install a heater to the wrong voltage bad things can happen.
120v circuit to a 240v heater will give you ¼ of the wattage
240v circuit to a 120v heater will burnout the heater and voids the warranty
If you are not sure about your voltage you will want to consult a licensed electrician. We stock almost every heater you see online and ship the same day if in stock so we can get it to you pretty fast
( FYI Notes )
110 volts, 115 volts, 120 volts, 125 volts
(All four voltages will work with the same heater)
220 volts, 230 volts, 240 volts, 250 volts
(All four voltages will work with the same heater)
208 volts is NOT the same as 240 volts – it’s a totally different
3. Noise level
All fan forced wall mounted heaters will make noise. We tell customers that when browsing our website the more expensive the wall heaters the quieter it’s going to be (this rule does not apply to our commercial-grade wall heaters with a CFM greater than 100) because the internal parts are of a higher quality.
If noise is not an issue to you any heater within the correct wattage and voltage parameters will work.
4. Looks at the grille
White this one is subjective; the look of the heater is an important part of the buying process. Every heater we have except the Broan WH9815is made with a metal grille with a powder-coated painted finish. If you have a question about the color of a certain heater feel free to call us
Controlling a wall heater can be done with a built-in or wall thermostat. Certain models have the option of one or the other, while some just have a single option for just built-in or just wall-mounted only. If you are not sure call or email us.
The built-in thermostat is the knob mounted on the outside of the heater. It works just like a wall-mounted heater: by turning it clockwise you turn the power on and you set the desired room temperature. Turn it counterclockwise you will lower the desired temperature wanted and if you turn it all the way to the left it will turn the unit off.
Wall thermostats are not available on all wall heaters, for those that do offer them this is how they work. A wall-mounted thermostat is usually mounted on the other side of the room.
A 120v or 240-volt power line is pulled behind the sheetrock to the wall heater. To set the temperature of the heater, once again, turn the knob clockwise to your desired room temperature.
When using a wall thermostat be sure to place it on an internal wall, ideally across from the windows. Avoid drafty areas, direct sunlight, and other heaters & electronics devices that can put out heat like computers or TV. Make sure you don’t place it behind a shelf or too close to pictures what will affect airflow around the thermostat’s sensors.
6. Bathroom wall heater locations
Find a spot on an interior wall close to the outside wall. Make sure you avoid any obstructions like a chair or couch or hanging items like drapes. By using a nearby wall you can avoid cutting into your wall insulation. The idea is to heat your cold wall first and the rest of the room will fall in line.
The factories recommend the heater should be mounted at least 8” from the floor, 8” from an adjacent wall, and if you are mounting it higher it has to be at least 8” from the ceiling, 3 feet from the furniture. If you have a question on mounting location(s) please consult your local town or city code inspector for the final answer
7. Recessed vs. Surface mounting
Recessed mounting simply means you cut a hole in the sheetrock wall.
Surface mounting is on a brick or block wall; your heater will mount on the wall instead of inside the wall.
8. Feature to look for or avoid.
- Backbox includes – Look for it – All heaters must have back boxes but sometimes you can order them separately. The backbox separates the heating element from touching the interior wall or insulation. It’s a code violation to not use a back box.
- Thermostat operation ranges – Look for it – Some people want to run the heater at the lowest temperature to keep the water pipes from freezing. If the operating range of 50° to 90° F, the heater will not go down to 40° F no matter how low you set the thermostat.
- Summer Fan Switch – Avoid – This is used for commercial building applications, all it means is that the fan will run but the heater will remain off.
- Heavy Duty Grille – Avoid – Another commercial building application, the greater the foot traffic the higher the odds of someone smashing in the front grille of your wall heater. Unless you have a hotel dolly rolling around your home you more than likely don’t need the added cost of a heavy-duty front grille.
Frequently Asked Questions
When should I select an Electric Ceiling Heater?
Electric ceiling heaters are designed for dens, basements, converted attics, breezeways, garages, bathrooms, small offices, workshops, and similar areas designed horizontal recessed installation, but are easily adapted for surface mounting. DO NOT MOUNT THIS PRODUCT ON A WALL OR SLOPED CEILING.
Electric ceiling heaters do not exhaust, they are fan-forced which means it’s designed to pull the cold air in through the heating element, and then shoot warm air out the other side of the ceiling heater. Unlike bathroom exhaust fans which simply through the air outside. Make sure you have a way to install a wall thermostat on an interior wall.
Can you mount a ceiling heater anywhere?
As a rule, no most wall heaters require you to mount it around 6′ from the floor and 6 to 12” from the wall. Most ceiling heaters are designed for 8′ high flat ceilings.
Read your user’s manual or a more accurate number for that model. Check with your local building codes before mounting above a bath or shower.
How many wires do I need to install a wall heater?
120-volt electric heater: 1 Hot (Black) 1 Neutral (white) and 1 ground (copper) wire.
240-volt electric heater: 2 Hot (Black) and 1 ground (copper) wire.
round. The 3rd wire is a 120-volt power supply for the motor or clock.
What do the wire colors mean?
120 volt has 1 black and 1 white wire connection
Your wire should match
Black to Black (Hot)
White to White (Neutral)
Copper to Green (Ground)
240 volt has either 2 black wires or 1 red and 1 black wire 1 ground wire
Can I take a ceiling heater and mount it on the wall?
As a rule, most ceiling heaters are not designed for wall installations.
Why do I need a thermostat?
Thermostats don’t forget to shut the heater off in the morning. If you use an on / off switch and forget to shut the heater off the heater will run all day. A thermostat will keep the room at a constant temperature; some people turn the knob down day and turn it back up in the morning.
What will harm a ceiling heater?
Never block unit air vents. This obstruction could lead to overheating, which could result in a fire. Do not insert or allow foreign objects to enter any air vent as this may cause electric shocks, fires, or damages to the unit.
How can you tell what your heater’s voltage is?
If you’re lucky the heater will still have its original factory sticker. This will show you the manufactures voltage, amps, and wattage. The voltage should always be rechecked will a voltmeter this is a device for testing the voltage from the breaker or fuse box.
What size heater do I need?
10’W x 15’L = 150 Ft2
150 Ft2 x 10 Watts = 1,500 watts
Can I paint my ceiling heater?
Most wall heaters are powder-coated instead of painted. In most cases, the warranty will be if VOID if any alternations are made to the heater.
How do electric ceiling heaters work?
Electric ceiling heaters are heaters that can be recess or surface mounted on the ceiling. They use 120 or 240 voltage to power an electrical heating element. Cold room air goes through the heating element and is shot out the other side as warm air. Ceiling heaters have a powerful fan to push the warm air down to the floor. This process is called Convection heat.
What Are the Dangers of Electric Ceiling Heaters?
Electric ceiling heaters must have an ETL, UL, or CSA certification with two or more safety features, high limit, and thermal fuse. Typically these go off if the heater is overheating because something is blocking the air from coming out. Per code flammable material like furniture needs to be three feet away
Can I leave my electric ceiling heater on during the day when I am not at home?
If your electric ceiling heater is controlled by a working wall thermostat the answer Yes. If there is no thermostat or it’s controlled by a switch (not recommended or to code) the answer is No.
What is the best electric ceiling heater voltage?
Sorry, it depends on your needs. The higher the voltage used the less current, and less resistance so it’s easier for the power to go from point A to point B.
How to Clean an Electric Ceiling Heater
Turn the heater off at the circuit breaker, test the heater to make sure it’s off, then take the grille off and vacuum the fan blades and element.
