Best Baseboard Heaters

Buying guide for Best baseboard heaters

While baseboard heaters may seem dated, they are a fairly efficient form of electric heating. Baseboard heaters can serve as a primary or supplemental heat system for your home. Through zone heating, you can control which baseboard heaters are running. This conserves energy and prevents your rooms from overheating.

Baseboard heaters are not right for all homes, but they can help combat drafty windows and heat individual rooms. The two types of baseboard heaters are convection and hydronic. Convection heaters work quickly but are less efficient, while hydronic heaters are slower but better for heating large spaces.

Single-pole baseboard heaters do not have an off setting. When you turn the dial to the lowest setting, you’re not turning the heater off. Instead, you’re turning it down to the lowest setting, often around 45°F. If the temperature in the house drops lower than that setting, the heater automatically comes on.

Is a baseboard heater right for your home?

Compared with other heating systems, baseboard heaters are fairly straightforward and easy to set up. They are not right for every home, but they have several advantages over other options.

Energy efficiency

Compared with space heaters, a baseboard system is far more efficient. It can outperform forced air and central air in some climates or if you have a smaller home. While heat pumps and radiant floor systems are more energy efficient, baseboard heaters operate with 100% efficiency, meaning that no heat is lost at any point in the process. All of it goes into your rooms rather than into your walls or outside.

Room or zone temperature control

If there are rooms of your home that are unoccupied for most of the day, baseboard heaters can be controlled individually or in zones to heat particular parts of your home rather than wasting energy heating the whole space. Small rooms heat up particularly quickly with a well-placed baseboard heater or two.

Quiet operation

If you have children or animals who might be bothered by the sound of a running fan, or if you just enjoy some silence, baseboard heaters are one of the quietest heating systems available. However, they may make “pinging” sounds as they heat up.

Minimal dust and allergens in the air

Since there’s no airflow produced by a fan, dust is less likely to float through the air when the heat kicks in.

Easy installation and maintenance

While you may still want an electrician to install them, the installation process is far easier and less expensive than forced air, heat pumps, or central air, all of which typically require ductwork within your walls.

Less heat loss through windows

The more windows there are in a room, the colder the room will be in the winter. Baseboard heaters placed beneath the windows are an ideal solution because they can warm just that room without overheating the rest of your home.

Heat in any room

Baseboard heaters can be installed where other heating systems present challenges. They do an excellent job of warming up a basement or crawlspace, for example. They can also be installed in chilly garages.

Baseboard heaters are not always the solution. If you have a large home, they may struggle to heat large rooms efficiently. Additionally, if you have pets or young children, baseboard heaters can be a safety threat as they can become extremely hot to the touch.

What is a convection baseboard heater?

Also known as electric baseboard heaters, these models have interior heating coils and fins that heat the air around them. The hot air rises and the heater draws in cold air in its place, which is then heated. This process is known as convection heating.

All-electric baseboard heaters are generally inexpensive, quiet during operation, and easy to install. Their maintenance requirements are low. However, they can cause burns if you, your children, or your pets touch them, and they can even start fires without sufficient safety features.

What is a hydronic baseboard heater?

Hydronic baseboard heaters use electricity to warm up a tube of water or oil. The fluid circulates through the tube and radiates heat into the room. The oil or water retains heat longer than the metal fins of an electric heater. Therefore, hydronic baseboard heaters are more cost-effective and energy efficient. Conversely, it takes a hydronic heater longer to warm up. That said, the risk of fire is lower.

What features should I look for in a baseboard heater?

Once you know which type of baseboard heater is right for your home, consider additional features like safety measures and installation methods.

Heating capacity

Larger rooms, especially those with high ceilings, may warm up quite slowly with baseboard heaters compared to forced air or central air. Baseboard heaters work best in hallways and small rooms. That said, hydronic baseboard heaters are the better choice for large rooms due to their heating efficiency.

Wattage is the main spec to make note of when determining which baseboard heater would do the job for your space. Unfortunately, it can be a complicated calculation, especially because each room may need a different number of baseboard heaters, and each unit must be placed on a wall without furniture against it.

For a basic rule of thumb, aim for 10 watts per square foot in each room. Add a bit of wattage for windows, doorways, and exterior walls, all of which can draw heat from the room.

Thermostat

Baseboard heaters either have a built-in thermostat or must be connected to a traditional wall-mounted thermostat.

Built-in adjustable thermostats require no additional installation steps and allow for individual control of a baseboard with the turn of a knob. However, this means you must bend down to reach the knob, which can be particularly annoying if you already have thermostats for another heating system in your home.

Most baseboard heaters fall into the second category and must be wired to a thermostat. While this makes installation challenging, it allows you to control a unit or a zone of heaters with a traditional thermostat. Single pole thermostats can’t be turned off and must be turned to their lowest setting to prevent them from turning your heaters on. Double pole thermostats can be turned completely off without having to turn the temperature to low.

Safety features

As with any heating appliance, safety features are crucial to keep you and your family safe. Here are the key ones to look out for:

Automatic cutoff: While your thermostat should tell any electric baseboard heater to turn off when the room reaches a certain temperature, malfunctions happen. When the unit detects a certain temperature range, it triggers its shutoff feature and stops operating. This feature is also called overheat protection.

Tip-over switch: Plug-in baseboard heaters may have a tip-over switch that detects when the heater is knocked over and shuts it off to prevent burns or a fire. Hardwired units do not need this feature since they are attached to the wall.

Installation

While baseboard heaters are far simpler to install than other home heating systems, there are still some important things to know.

Portable baseboard heaters can simply be plugged into the nearest outlet of the appropriate voltage and placed against the wall.

Hardwired heaters are more involved. Units connect to the power source either through knockouts or with cable clamps. Included cable clamps are useful, but sometimes you need to run wires through the knockouts to connect the power supply. Included universal wiring can simplify this process even further or make it easier to install the unit where you want.

If a baseboard heater has a built-in thermostat, you don’t need to worry about connecting to a traditional thermostat. Otherwise, you will need to run wires from the thermostat to the appropriate lines in the junction box of the heater.

Mounting is fairly straightforward. If there's an existing baseboard where the new unit will go, you can remove it. Measure the old unit to see that the new heater will fit properly. Pre-drill holes in the wall, aligning with studs. Then, use screws to attach the heater, either by mounting holes in the back or by drilling your own holes in the back, if necessary.

Accessories

Single-pole thermostat

Baseboard heaters don’t always come with thermostats, requiring you to find one separately in order to control the heater. There are two types of thermostats, and you’ll need to get the correct one for your heater. Single-pole thermostats have two wires.

Double-pole thermostat

If your baseboard heater has a four-wire connection, you need a double-pole thermostat that also has four wires in order for it to function correctly.

Heat covers

A heat cover reduces the chances of pets and children burning themselves on the hot fins.

How much do baseboard heaters cost?

Inexpensive

The least-expensive baseboard heaters cost $30 to $50. These are electric heaters that are 3 to 4 feet long.

Mid-range

These baseboard heaters cost $50 to $150. These are usually higher-quality convection baseboard heaters that are over 4 feet long.

Expensive

Any baseboard heater over $150 is a premium model. This is where you’ll find hydronic baseboard heaters. Their added complexity increases the price.

Most baseboard heaters come in neutral color options, such as white, gray, or beige. Take note of the particular shade, however, as some baseboards appear slightly darker or lighter in person than they do in photos.

Tips

• Do not install a baseboard heater under an electrical outlet. The heat could trigger a short circuit in the outlet, leading to a fire.

• Always leave 12 inches of space on both ends of a baseboard heater, in front and on top. If anything is too close to the heater, there is a risk of spontaneous combustion from the heat.
• Don’t place furniture in front of a baseboard heater. It will block the warm air from heating the room.

• You should only have one thermostat per room, even if there are multiple baseboard heaters. Multiple thermostats will be influenced by heat from other heaters, causing them to switch on and off unpredictably.

FAQ

Q. Should I vacuum my baseboard heater?

A. Yes. Regular vacuuming will prevent the heater from creating a burned dust smell when turned on after a prolonged period.

Q. Should I put heat covers on a baseboard heater if I have children?

A. Yes. Small children are curious about their surroundings and haven’t learned to be afraid of much. Consequently, they’ll stick their hands into any place they can. Heat covers will keep them from burning their hands and fingers on a baseboard heater. Covers will protect your curious pets, too.

Q. What is the best location for a baseboard heater?

A. Baseboard heaters should be installed under windows. Windows are always the coldest part of any room. The cold air coming from a window will sink toward the floor and spread out across the room unless it is immediately heated. A baseboard heater under the window will heat the sinking cold air, thus keeping the room warmer than if the heater were positioned somewhere else.

Q. Should baseboard heaters be added to a home with another heating system?

A. If there are areas of your home that struggle to stay warm despite the best efforts of forced air or central air, a few baseboard heaters can supplement your existing system. An energy assessment can help you identify the areas that would benefit most from the addition of a baseboard heater.
