Electric Baseboard Heater Buying Guide

If you need some additional help on how to choose the best electric baseboard heater for your home, then the following information can help.

Below, you’ll find out all about baseboard heaters, including how they work, the various types available, and answers to common questions people have about these home heating units.

What is a Baseboard Heater?

Best baseboard heater

Baseboard heaters are basically zone heaters. These units are typically installed underneath windows where the heater’s rising air counteracts the cool air coming from the windowpane. Baseboard heaters come in three types: electric, hydronic, and plug in models.

Baseboard heaters are different from other types of heaters like a wall heater in the sense that they are installed (or placed) along the floor. The best electric wall heaters are compact in size but do still take up some wall space and not the most preferred option for some people.

Another thing to know is that baseboards offer a cheaper alternative to traditional heating as they are generally inexpensive to run. Depending on the size of your room, you could be looking at a cost of as little as $0.06 per hour by running an electric baseboard heater.

These units also make a great source of supplemental heat, allowing you to add extra warmth or diminish the impact of cold air flowing through a window pane.

How Do Baseboard Heaters Work?

Baseboard heaters use the process of convection to draw cold air from the floor and warm it up through the unit before releasing the air back into the room where the heat rises. As the air cools down, it sinks to the floor and is taken back into the baseboard heater to be cycled through again.

Most baseboard heaters contain a metal heating element that warms up when an electrical current is passed through it. This element is surrounded by fins (usually made from aluminum) that radiate the heat generated throughout the room. 

Some baseboard heaters use a hydronic heating process where a non-toxic fluid that’s held in an internal reservoir is warmed up and releases heat into the air.

Baseboard heaters are also fanless, so they don’t blow hot air throughout a room. Instead, they use convection heating to generate warmth. This means that they can retain the warmth contained within the heating element for longer, even when the heater has been switched off. 

According to the U.S. Department of Energy, “baseboard heaters are usually installed underneath windows. There, the heater’s rising warm air counteracts falling cool air from the cold window glass.” When you install a baseboard heater underneath a window, the warmth generated by the heating element rises and, in turn, allows cold air entering the room to fall to the floor. This cold air is then sucked in by the baseboard heater and is released as warm air. All without the need for a fan.

This process is repeated until the desired temperature you’ve selected on your baseboard heather’s thermostat has been reached. Once it has, the baseboard heater will automatically shut itself off. As soon as the temperature begins to dip, the baseboard heater starts up again. 

It is worth noting that even the best baseboard heater takes a little longer to warm an entire room than a wall heater. However, they are much better at retaining heat. Unlike most wall heaters, they’ll continue to warm a room once they have been switched off.

Types of Baseboard Heaters

There are three different types of baseboard heaters to choose from and, although each works in a very similar way, the installation of each is quite different. 

This is something that you need to consider before purchasing, especially if you’re wondering how to install a baseboard heater.

Electric Baseboard Heaters

Best electric baseboard heater

The first type of baseboard heater that we’ll look at is electric baseboard heaters. These units are designed to be hardwired into an external thermostat, using your home’s existing wiring as a power source. 

Installing an electric baseboard heater can seem like an overwhelming task but it’s fairly straightforward. A little further down, we’ll take you through a step by step guide on how to install an electric baseboard heater. Or you can just hire an electrician to do the job for you.

Hydronic Baseboard Heaters

Best hydronic baseboard heater

Hydronic baseboard heaters also need to be hardwired to an external thermostat; however, the inner-workings of this type of heater are a little different.

According to Apollo Heating & Air Conditioning, “a hydronic radiant system circulates heated water or antifreeze through a hidden piping network in order to deliver warm, efficient comfort throughout every room in the building.” Instead of using a metal heating element, a reservoir filled with non-toxic fluid is heated. This works in the same way as traditional heating, like water being warmed by a boiler and the heat from it being radiated out into a room through a series of pipes.

Generally speaking, hydronic baseboard heaters are the most efficient type for holding onto warmth for longer periods once the heater has been switched off.

They are usually designed to stay cool to the touch while they’re running too, so they make a good choice for family homes with young children or pets.

Plug In Baseboard Heaters

Best plug in baseboard heater

Finally, you have the choice of a plug in baseboard heater. These do not need to be hardwired into the existing electrical circuits of the house and can simply be plugged into an electrical outlet instead. 

This allows anyone to own and operate a baseboard heater as well as move the heater from room to room as desired, rather than having one permanently installed along your baseboards. 

The best plug in baseboard heaters also feature a built-in thermostat, so you don’t have to worry about the extra expense of installing an external unit to regulate the temperature. 

Electric Baseboard Heating Pros and Cons

While electric baseboard heaters are undeniably a fantastic choice for most homes, there are some features that may not work for you. 

To help you decide whether purchasing a baseboard heater is the right choice for your needs, we’ve put together a list of advantages and disadvantages  below.

Pros

  • A good choice for rooms that are difficult to heat.
  • Provide excellent zonal heating by warming cold spots throughout the room.
  • Ideal for providing supplemental heat in large rooms.
  • Can be installed as permanent heating solutions or used as a portable heater.
  • Easy to clean and maintain.
  • The absence of a fan gives them an extremely low self-noise output.

Cons

  • Can take up to an hour to reach the ideal temperature.
  • You cannot place furniture in front of them and they need at least 12 inches of clearance.
  • Are most effective when placed underneath a window where it can counteract the cold air flowing in.
  • Although easy to maintain, they do require regular cleaning as they have a tendency to collect dust.

Common Baseboard Heater Sizes

Electric baseboard heaters come in a variety of sizes, making it easy to choose the right size for your room. You may even need more than one unit if you have a particularly large room with several windows.

To give you a better idea of the most common baseboard heater sizes available, along with the space they’ll adequately cover, take a look at the chart below:

LengthWattage Coverage
24-inches500W (240V)50 to 75 square feet
36-inches 750W (240V)75 to 100 square feet
48-inches1000W (240V)100 to 125 square feet
60-inches1250W (240V)125 to 150 square feet
72-inches1500W (240V)150 to 200 square feet
96-inches2000W (240V)200 to 250 square feet

When calculating the length and wattage you need, a good rule of thumb to follow is to allocate 10W per square foot and then add an additional 25 square feet to allow for the room’s height. 

For example, in a room measuring 100 square feet, you’ll want at least a 1000W heater (10W x 100 + 25 square feet), giving you coverage of 125 square feet in total. 

This will ensure that the room warms up quicker and continues to stay warmer for longer once you’ve switched the baseboard heater off. 

Another option would be to buy a large space heater that can be mounted high up on the wall or come in a portable design if you want the most convenience in a new unit.

How to Install an Electric Baseboard Heater

Installing an electric baseboard heater can seem like a daunting task, especially when you consider that you’ll need to hardwire it into the home’s existing wiring. 

Contrary to popular belief, it isn’t as difficult as you might think. However, if you’re not 100% confident with installing an electric baseboard heater yourself, then it’s a good idea to call in a professional electrician. Dealing with electricity is hazardous and it needs to be done correctly.

Here is a step by step guide on how to install an electric baseboard heater:

  1. The first thing you need to do is shut off all power to the room you’re installing your electric baseboard heater in. You can do this from your main circuit panel.
  1. Next, test the supply wires with a multimeter to make sure there isn’t any electricity running through them.
  1. Remove the screws from the wiring cover on your heater. These will usually be located at one end of the heater, although some heaters can be wired from either end. In this case, you’ll need to decide which end to wire it from.
  1. Place your heater close to the wall so that the wires coming from the wall can be inserted into the heater’s knockouts.
  1. Thread the supply wires coming from the wall into your junction box through the knockout holes. Note: some heaters use cable-clamps instead of knockouts.
  1. Attach the ground wire from your supply to the ground wire in the heater’s wiring compartment. This is usually color-coded green.
  1. Next, separate two joined wires inside your heaters wiring compartment by pulling them apart. These will usually be color-coded red and black, but some baseboard heaters will have two red wires.
  1. Connect the red wire from the heater to one of the red coming from your supply. If your heater has two red wires, you can connect the supply wire to either.
  1. Connect the black (or remaining red) wire to the black supply wire.
  1. Neatly fold the connected wiring into your heater’s junction box, then replace the cover and screw it firmly in place.
  1. Now, take a stud finder and locate the wall studs. Mark the stud locations in the position you want to mount the baseboard heater.
  1. Place the heater flat against the wall and line up the mounting holes with your stud marks. Place a level on the heater to make sure it’s straight. If it isn’t, slightly adjust your marks until it is.
  1. Once the heater is level, insert a screw into each of the mounting holes and drive it into the wall using a drill. Note: If your heater is longer than 6-feet, insert a screw into the center mounting hole as well.
  1. Make sure that the heater’s thermostat is off, then turn the power supply to the room back on.
  1. After five minutes have passed, check the heater to make sure it isn’t warming up while the thermostat is off. If it is, there’s a chance that the heater could be defective or the wiring hasn’t been done correctly. If it isn’t warming up, turn the thermostat to its highest setting and wait for another 5 minutes. If it isn’t starting to warm up, cut the power to the room and check your wiring again.
  1. Once your baseboard heater has started warming up after five minutes (with the thermostat on it’s highest setting), allow it to run for 30 minutes. This will allow it to remove any oils and residues that might still be present from manufacturing.

Common Questions About Baseboard Heaters

Is an Electric Baseboard Heater Expensive to Run?

While running a baseboard heater is a relatively economical way to warm a room, the amount it costs will ultimately depend on two factors: the size of the room you’re warming up and the wattage of the heater.

If you’re wondering, “do space heaters save money“, the answer is yes when compared to the costs to run a central heating system. Keep in mind that electric baseboard heaters are a good way of adding supplemental heat to a room too. They don’t just have to be the main heating source.

If there is a particularly cold period of weather, baseboard heaters can make a great option of generating a little extra warmth at an even lower cost than referenced in the chart above.

How Much Electricity Does a Baseboard Heater Use?

Baseboard heaters will use as much electricity as the power consumption in watts. Electricity companies use kilowatts per hour (kWH) to calculate usage.

A 500W baseboard heater will use 0.5W of electricity per hour. A 1000W baseboard heater uses 1KW per hour, a 1500W baseboard heater uses 1.5KW, and a 2000W baseboard heater uses 2KW of electricity per hour.

Are New Electric Baseboard Heaters More Energy Efficient?

As technology advances, appliances are becoming much more energy-efficient. Newer versions of electric baseboard heaters are no exception to this rule, and there are some really energy-efficient options available.

Some of the best electric baseboard heater brands can convert 100% of the electricity they use into heat.

Is it Safe to Leave Baseboard Heaters On?

As a baseboard heater will automatically turn itself off once the desired temperature selected on the thermostat has been reached, it is safe to leave them on.

Many baseboard heaters include overheat protection and a tip-over switch that makes it safe for them to be left on without fear of a fire occurring.

One thing you do need to remember; however, is to clean your baseboard heaters regularly by vacuuming dust from the vents.

This is even more important if you’re planning on leaving your baseboard heater on 24/7 as it will reduce the risk of something flammable heating up and keep the heater functioning more effectively.
