Types of Bathroom Heaters

There are several types of bathroom heaters on the market. Each type has its own advantages and weaknesses. Some of the heaters’ designs are meant to increase heat distribution, while others enhance versatility. What types of bathroom heater you end up with all depends on your needs and how much you are willing to pay for it. Read on below to learn more about the five most popular types of bathroom heaters.

1. Portable

They are small, easy to carry around, yet good enough for heat distribution in small bathrooms and offices. Portable bathroom heaters are best suited for people who only need a bathroom heater during the cold seasons only. That way, you can remove the heater from your bathroom and use in other rooms whenever you want to.

So, how do they work? Portable heaters are electric powered and have a heater element that changes electrical power into heat. However, to distribute the heat around the house, these heaters often utilize a fan that forces the hot air inside the heater out into the bathroom space. Unfortunately, while they are cheap and effective for small rooms, portable heaters require regular cleaning if you want to keep them efficient.

2. Ceiling Heaters

Are you skeptical about buying a wall heater since you don’t want to incur extra electrical configuration costs? A ceiling heater could be your best bet. Small, reliable and easily glides into any ceiling box, ceiling heaters are the best options when you have a ceiling box ready to place a heater or fan. Most ceiling heaters are portable heaters which you could uninstall and install in other parts of the house. However, they are also great choices when you want a permanent heater in your bathroom. Once you install them properly on the ceiling, they could serve you for as long as they can last.

3. Wall Mounted

As the name suggests, a wall mounted bathroom heater is attached to the wall. The heaters come in different designs such that some will be attached on a hook while others are meant to be screwed permanently on the wall. They are effective heat distributors in small bathrooms and can be durable as well. Most wall heaters are also inexpensive.

4. Heater and Exhaust Fan

Since bathrooms are places associated with a lot of steam and chilly humidity, you could as well buy a unit that eliminates both chilly humidity and provides heat instead. Heater and exhaust fans are designed to solve two problems, essentially offering heat in the bathroom in exchange for eliminating steam that affects walls and other devices. They are more expensive than other heaters but are certainly more helpful than heaters unable to eliminate moisture in your bathroom.

5. Combination Heaters

Combination heaters or space heaters utilize integrated heat pump systems that could provide heat in large rooms as well as heat water or provide cooling solutions. These combination heaters are very efficient and are estimated to conserve energy costs by up to 10%. While they are expensive, combination heaters are ideal for a family that wouldn’t mind having a system that provides heat at home as well as delivers hot water to the shower heads and sinks.

Best Bathroom Heater Buying Guide

When trying to decide which good bathroom space heater to buy, you can arrive at your decision by following a very simple process. There are not many factors you need to keep in mind, but nonetheless, carefully evaluating the following factors will help you save money and get the right heater for your home.

Power Provided

You know that a bathroom heater can serve your needs by looking at its power capabilities. In a small bathroom with only the basic units, a heater that supplies between 600 watts and 1500 watts will be ideal. Most bathrooms on the market have enough power capability for a small bathroom, which is why looking at the next feature is important.

Heat Distribution Range

Don’t just get satisfied by the fact that your ideal heater has 1250watts. Instead, ask how large a bathroom can that heater serve? If the heater can only handle a 90 square feet bathroom and you have a 100 sq. ft. bathroom, look for a bigger heater one. Most heaters perform poorly when their heat distribution systems get clogged, meaning the smaller range heater will never adequately serve your needs? Fortunately, most heaters will provide estimates of the size of the bathroom they can serve. Compare the estimates with the size of your bathroom and pick a heater that will serve you accordingly.

Installation Type

Bathroom heaters can be installed on the wall, the ceiling or provide heater distribution while they lay somewhere in your garage. Most heaters designed specifically for bathroom space heating are small and easy to install on the wall or ceiling. Pick a ceiling fan if you have a ceiling fan box in your bathroom. Alternatively, choose a wall mounted heater that could be screwed permanently to the wall for safety reasons.

Thermostat Controls

Whether you prefer a manual set device or one with digital controls, the choice lies in your hands. A digital control panel will often have more options. It is also easier to control. By contrast, manual control panels allow you to change heat settings albeit not precisely as a digital heater would.


One of the most prudent decisions you can make when buying a bathroom heater is picking one that will serve you for a long time. Look at the materials used to make the unit, read online reviews and go for a heater that will outlast its era. If not, you may end up picking a heater that will need cleaning every couple of days in order to distribute heat.

Where and How to Install a Bathroom Heater

While you may have heard that heaters can be attached to the wall or ceiling, it asks for more diligence to know that your ideal heater can perfectly attach onto the location you want it. With a wall heater, for instance, you must know whether it is hooked or screwed permanently on the wall. If you have to screw the unit, you must have enough unobstructed space on your wall.

If you decide to buy a heater and extractor fan, you have several decisions to make before you can install the unit. Assess your venting option and drill a duct that will help force moisture out of your bathroom. Of course, the duct should be drilled in a way leading out of the bathroom. If you have a ceiling heater, you must have an electricity cable to serve it. On the other hand, if you are someone with no intention to have a heater visible in your bathroom, consider radiant floor heating. Radiant floor heater installation ensures that the heater lies some distance away from the drainage system on the floor, but with the ability to produce heat to your bathroom.

How to Install a Bathroom Heater

Once you determine the location to install your bathroom heater, switch off the main electrical supply unit and follow the following instructions:

  1. Step1: Mark and Drill Installation Holes

    Since most bathroom heaters are screwed onto walls or ceilings, prepare to make some drilling in your bathroom. Place your heater exactly where you want to install it and mark the places screws will pass through. Use the right drill to make holes on those marks and hang your heater properly. Use fastening bolts if your wall is made from gypsum plasterboard.

  2. Step 2: Electrical Connection

    An electrical connection can be trickier than hanging the heater. But it isn’t impossible when you have the right tools. Simply follow instructions provided and pay special attention to the supply voltage needed by your heater. Make the appropriate electrical wiring needed or call a professional for help. Modern bathroom heaters will often feature an electrical outlet and cable for easy connection once you complete the wiring.

Costs to Run a Bathroom Heater

No one wants to pay large sums of money on electrical bills every year. Few people can afford to waste money on unnecessary bills anyway. This makes it extremely prudent to buy a bathroom heater that will incur minimal energy costs. Additionally, you will need a heater that isn’t too big for your needs, as this could mean more energy costs that could avoid

The cheapest option when considering an energy saving bathroom heater is a portable heater. They are small and mainly designed for small bathrooms. Portable heaters will often utilize a heating element with no more than 1500watts power production. However, the heaters will be more effective depending on where installed. Generally, ceiling heaters are more effective in heat distribution compared to a wall mounted ceiling. Ceiling fans are also safer and sometimes more energy efficient.

The priciest of bathroom heaters are those installed on the floor. Some people know them as radiant floor heaters, and they are great if you don’t hate installing devices in the visible location of your bathroom. When it comes to costs of maintenance, however, you won’t like them. Not only are they expensive to install, but they are also costly when they malfunction. If your costs of running a bathroom heater are deep in your mind, avoid radiant floor heaters.

Bathroom Heater Safety Tips

Safety should always be your priority when buying any electrical device. With bathroom heaters, the safety of the heater is determined by its way of installation and design. Many brands provide what is known as IP safety number to guide you on the distance to your showers you should install the device. Usually, the farther away from the water sources you install your unit, the better. Generally, ceiling mounted heaters are safer than their wall counterparts. However, a well mounted wall ceiling can still provide the safety your family deserves.

A quality bathroom heater can keep you warm as you take your showers, but it could also expose you to danger. Take the following precautions and safety tips to ensure you and your family members are always safe from the dangers associated with such an electrically powered device.

  1. Buy a heater with a thermal overload protection. Sometimes heaters overheat, which could expose you to grave danger. Take the precaution of buying a heater with a thermal overload protection mechanism. This way the heater can shut off when it overheats or tips over.
  2. Hang the heater’s electrical cord. The last thing you want in a bathroom is anything that could trip you in a bathroom. Even without a heater, falling in a bathroom is risky. Take the extra caution of hanging any electrical wires in a way they couldn’t fall.
  3. Avoid Touching the Heater. Older model bathroom heaters are not flame resistant. They burn like hot iron. Bathroom heaters that run quietly are especially dangerous because you can tell whether they are operational or not. Choose a modern heater that is flame resistant. Alternatively, buy a heater whose outer casing is fireproof and not dangerous if you accidentally touch it.
  4. Avoid Window Bathroom heaters. If you find a heater that asks you to install it near the bathroom window for efficient heat distribution, avoid it. If you buy it, ask a professional to install it correctly. Window bathroom fans easily trip and cause harm as they draw air from the exterior of your bathroom.
  5. Regularly inspect and clean your heater. Every two weeks, inspect your heater to check for debris clogging. Remove the exterior casing and clean the heater while the power source is already turned off.
  6. Shut it off when not in use. If your heater is manually operated, always shut it off and preferably unplug it after use.

Bottom Line

You probably want to buy a bathroom heater because you are tired of showering while the whole bathroom is cold. Maybe your old heater is inefficient. But in spite of your reasons, buy the best bathroom heater you can afford. At your own budget, you can find a heater that is easy to install, effortless to maintain and efficient for your bathroom needs. If you revisit our bathroom heater reviews above, you will probably find one capable providing heat in your bathroom efficiently. But for now, consider the type of bathroom heater your family deserves, evaluate your options and later buy the heater for them.
