Buying Guide: How to Buy a Bathroom Heater?

How does a Bathroom Heater Work?

A bathroom heater is a small appliance that you can fit in your bathroom. A heater will appear in one area, usually on a wall or ceiling or on a shelf.

The heater produces warm air through a small mechanism. A ceramic heating element or another item will be warmed up. The air goes throughout the bathroom through a blower or fan.

You can adjust the warm air with a few knobs or other controls. The most important part of the heater is that it can operate in a humid environment. You’ll have to ensure your bathroom heater is rated to where it can work in such an area. The humidity in your bathroom can be substantial, especially when you’re taking a shower, shaving, or doing something else that requires plenty of water.

Things to Consider When Choosing a Bathroom Heater

There are multiple points that you can use when looking at a bathroom heater for your home:

1. Heating Capacity

Look at how well the heater can operate in your bathroom. A heater may be measured based on how many square feet of space it can warm.

2. Energy Usage

All bathroom heaters use energy in some form. A heater can be measured according to its wattage. A unit that uses more watts will produce warmer air and can operate faster, but it will also use up more energy.

3. Settings

You can use various heat settings on a heater. These include multiple settings based on how intense the heat should be in your room.

Some sensors may also identify when the conditions in your room are changing in some way. A sensor can start the heater up when the surrounding temperature reaches a certain threshold. The feature can also stop the setup when it gets too warm.

 4. Placement

Many bathroom heaters can be placed on a shelf or counter in your bathroom. But others can also be installed on your wall or on your ceiling. Such mounted or recessed heaters might take an extra bit of time to install, but they might be easier to use and can allow for more air to move through.

5. Safety Features

A heater should come with sensors to identify when the heater should stop working. A metal grill or other sturdy covering is also needed to ensure no one will come in direct contact with any of the heating elements.

A safe model should include cool-touch housing that won’t be too intense. It should also feature a wiring setup where all the connections stay inside and won’t be exposed, thus producing a safer body.

Measuring the Wattage

A good idea to consider for your heater involves looking at the wattage produced versus the square footage of your room. A good rule to use is to get 10 watts of power in your heater for every square foot of floor area in your bathroom. The measurement should work in a bathroom that is well-insulated and has a ceiling that is about eight feet high.

If your bathroom is 150 square feet, you should aim for a heater that works at 1500 watts. A larger master bathroom at 250 square feet could use something that works at 2500 watts. A powder room at 75 square feet only needs a 750-watt model. You’ll have to be sure you plan the right wattage for your heater based on what fits.

Benefits of Bathroom Heater

A bathroom heater is ideal for many reasons:

  1. You can keep steam from building up around your bathroom after a shower. When you use a heater alongside a traditional bathroom fan, you can allow the air to move around a little better, thus preventing all that moisture from building up around your mirrors and other spots after you shower.
  2. A heater will also dry out your room a little faster after showering or doing other things. Your baseboards and other fixtures will not be at risk of premature fatigue.
  3. Your bathroom heater can also help you to feel relaxed in the morning. Your joints, muscles, and other parts will feel more stimulated.
  4. You may also experience better cardiovascular circulation when you use a bathroom heater. The warm air can help you feel more comfortable in the morning.
  5. It may be easier for you to use the bathroom in the morning if you have a quality heater on hand. The cold conditions in your bathroom during the early part of the day can be difficult to bear, but a heater ensures you won’t have to worry all that much.

Safety Tips For Bathroom Heaters

While today’s bathroom heaters can feature various safety points, you’ll still have to watch for how you’re going to use your model. You’ll have to use a few points when getting a heater ready:

  1. Be sure the heater is in an area where it remains stable and secure. A wall-mounted or ceiling-installed unit is best.
  2. Keep the wiring and other features around your heater from being exposed. The wires could create a fault.
  3. Avoid getting water directly into the heater. The unit may not work as well if you splash water all around. While a bathroom heater can handle added humidity, the point does not mean it can persist in any watery condition.
  4. Check on how well the heater operates on occasion. You might have to clean the grill out to prevent dust and other things from building up.
  5. Many heaters come with filters. You would have to clean out a filter on occasion to ensure the heater remains safe for use.

Installation Tips and Requirements

Items Necessary

The following tools are necessary when aiming to install a bathroom heater:

  1. 14-2 or 12-2 cable
  2. Drywall screws
  3. Electric tape
  4. Plywood
  5. Screwdriver, drill, and pliers
  6. Cutting tools; a drywall saw is ideal, although a circular saw may also help
  7. Stud finder
  8. Extension cord; look for a new model that doesn’t appear worn

The Steps Necessary

It is best that you consult an electrician to install a new heater. An electrician can help you identify live wires and other connections that have to be avoided.

The steps that your electrician can use will ensure the best possible experience for your heater, but it helps to know them yourself to understand what’s going to happen. The process for installing a bathroom heater entails the following points:

  1. Check on where the electric connections are around your bathroom. The work includes looking at how well you can get a heater and thermostat installed. You can use this to identify the ideal locations for the two parts.
  2. Add a 12-2 or 14-2 wire through the ceiling drywall. The link should go between the locations for the thermostat and heater.
  3. Open the appropriate holes in your walls for the heater and thermostat. Be sure to watch for any studs that might appear. A stud finder can help.
  4. Run the wire you used earlier to the areas for the thermostat and heater. You can produce a ¾-inch hole in any spots around your plywood where needed.
  5. Apply the appropriate electric wires to your heater and thermostat. Check the specific instructions that work with whatever heater model you use.
  6. Secure the housing for the two parts. You might need to apply plywood around the outside areas to create a steady body. You may also need to add some mounting screws around your heater to ensure everything works.
  7. Make sure the connections are secured and that the wiring works.

Remember to contact a professional electrician for help and to ensure the safest possible experience when getting your heater ready.

What About a Portable Model?

You also have the option to use a portable bathroom heater if you prefer. The heater would require you to plug the unit into an appropriate power outlet. The work might be useful, but you’d have to be cautious when getting your heater ready. A wall or ceiling-mounted model might be safer because of how it’s not going to be at risk of tipping over. Also, a portable unit might not deliver the warm air you need all the way, although this could vary based on how well you can get your heater set up where you are.

Cost to Run

The expense for running a bathroom heater will vary based on how often you use it and whatever the local electric rates are at your property. You can figure out the cost to run by multiplying the kilowatts being used by your local electric rate to get the total cost for running something for an hour.

Let’s say you have a 1500W unit, and the electric rate was 10 cents. By multiple 1.5kW by 10 cents, you’ll get 15 cents per hour. It would cost $3.60 to run the heater for 24 hours.

The lightweight energy usage involved would be a useful point for the bathroom heater. You’ll find that a heater won’t produce as much energy as you might expect, although you’d have to ensure you only use the heater when necessary to keep from using more money in the heating process than what you wish to use.

The versatile functionality of a heater is worth noting, but it helps to ensure that your heater is operational and that you can find something easy for use.

You have to find a choice that is efficient as well. You’ll find that many bathroom heaters don’t produce as much warm air as you might assume, but you’ll have to look at how well you can control the heat on your model.
