Have you ever walked into a room that was too cold no matter how high you set the thermostat? Or maybe you've been in a room that never seems to get any cooler in the summer.
As an engineer, you know that controlling the temperature is important for keeping places comfortable and useful.
Baseboard heaters can help with this.
These quiet heaters have been keeping us warm for decades, but many people still don't know how they work.
In this article, I'll talk about what baseboard heaters are, how they work, and why they're important for anyone who wants to build spaces that are efficient and good for the environment.
Prepare to get toasty with baseboard heaters.
Introduction to Baseboard Heaters
Formal definition:
Heating elements installed in panels along the baseboard of a wall.
There are different kinds of baseboard heaters, and each one heats in a different way.
Convection and hydronic baseboard heaters are the two most common kinds.
Factors to Consider When Choosing a Baseboard Heater
When choosing a baseboard heater, you should think about a few things to make sure you get the right type, size, and heating capacity.
- Footage Square.
When choosing a baseboard heater, it's important to think about how big the room is.
The heater needs to be stronger the bigger the room is.
- Location.
Rooms on the outside of a house or in the basement may need more heat than rooms in the middle of the house.
- Insulation.
How much heat a room needs will depend on how well it is insulated.
A room that is well insulated will need less heat than one that is not.
- Number of Individuals.
When there are more people in a room, it will need more heat.
Choosing the Right Baseboard Heater
The type of baseboard heater you get will depend on where the power comes from and how much space you have.
Electric baseboard heaters work well in bedrooms, bathrooms, basements, dining rooms, living rooms, and hallways that are about the same size.
They give off a lot of heat while running quietly and without taking up any floor space.
Hydronic fluid-based systems can be used to heat your whole house, or they can be used to heat only certain rooms or parts of your house.
They use less energy than electric baseboard heaters and can save you money over time on your energy bills.
When choosing an electric baseboard heater, it's important to think about how much heat it puts out, where it gets its power, how long it is, whether you want an onboard or wall thermostat, and how much it costs to run.
Electric baseboard heaters are usually installed permanently, so it's important to get the right size.
The size of an electric baseboard heater for a room can be determined by the manufacturer's recommendations or by multiplying the room's square footage by a base number.
In conclusion, baseboard heaters are a good way to heat a room that doesn't take up much room.
There are different kinds, with convection and hydronic being the most common.
Baseboard Heater: The Unorthodox Solution to Keeping Your Feet Warm
Still hard to understand? Let me change the point of view a bit:
Are you sick of your feet being warm in the winter? Do you wish you had a heater that only warmed your legs and feet?
You don't need to look any further than the baseboard heater if you want to feel both cold and hot at the same time.
The baseboard heater is the best way to heat your home without messing up the way your baseboards look.
It has a low profile and doesn't stick out too much.
So why hold out? Invest in a baseboard heater today and have the questionable pleasure of having your feet only partly warm.
Okay, that was just a joke made to look like a TV ad.
Now let's go back to the explanation.
Installation and Replacement of Baseboard Heaters
To install or replace a baseboard heater, you need to get ready, handle it carefully, and follow the instructions from the manufacturer.
Here's what you need to do:
- Shut off the electricity.
- Take off the old heater and unplug the wires.
- Get the new heater ready and connect it to the wires, making sure to carefully follow the instructions from the manufacturer.
- It's important to know that installing or replacing a baseboard heater may require a licensed electrician or heating, ventilation, and air conditioning (HVAC) professional.
For safety reasons, it's not a good idea to do it yourself.
The cost of replacing or putting in a baseboard heater depends on things like the type of heater, the cost of labor, and where the heater is.
Baseboard heaters can cost anywhere from $25 to $250, but that doesn't include installation.
On average, buying and setting it up can cost between $300 and $500, at the time of writing.
Maintenance and Safety Precautions
Baseboard heaters need regular maintenance and safety precautions to keep people safe and get the most heat out of them.
Here are a few things to remember:
- Safety clearance: A baseboard heater should have at least 12 inches of space around it for safety.
Clear three feet in front of the heater, six inches on each side, and 12 inches above it.
Don't put furniture or things that can catch fire near or on the heater.
- Maintenance: Baseboard heaters should be properly maintained to avoid fire hazards and get the most heat out of them.
Clean the inside and outside of the heater every so often with a vacuum to get rid of dirt and dust that could block airflow and cause the heater to get too hot.
Nothing should be put in front of the heater that would stop air from getting to it.
One thermostat should be used for all baseboard heaters.
- Be careful around kids.
Baseboard heaters can be dangerous for kids.
Children shouldn't touch these heaters because some of the baseboard heater elements can cause serious burns if they come in direct contact with the skin.
When using baseboard heaters near children, it is important to be careful.
In conclusion, baseboard heaters need to be taken care of properly and with safety in mind.
When installing or replacing a baseboard heater, make sure to follow the manufacturer's instructions carefully and think about upgrading to a more energy-efficient model.
Keep furniture and things that can catch fire away from the heater, clean it every so often with a vacuum, control all heaters with one thermostat, and be careful around kids.
Types of Baseboard Heaters
There are two main kinds of baseboard heaters: convection and hydronic.
Convection heaters use electric resistance to heat the air, which is then pushed out of the unit while colder air comes in through the bottom to be heated.
On the other hand, hydronic heaters heat a room with hot water or another non-toxic fluid.
They use less energy than convection heaters and are often used in conjunction with a central boiler to heat the whole house.
Hydronic Baseboard Heaters
Hydronic baseboard heaters heat the room with hot water or a fluid that isn't dangerous.
The fluid is heated by a boiler or some other source outside of the heater before it is pumped through the heater and lets off heat into the room.
Convection baseboard heaters use more energy because they turn on and off more often.
Hydronic baseboard heaters use less energy because they turn on and off less often.
Hydronic heaters cost more to buy up front than convection heaters, but they save a lot of energy and pay for themselves many times over.
Electric Baseboard Heaters
Electric baseboard heaters are a type of convection heater that heats the air directly by using electricity.
They are usually hardwired into the home's electrical system and run on either 120 or 240 volts.
They don't need a furnace, boiler, or any other extra equipment to work.
Hydronic heaters are more efficient than electric baseboards, but electric heaters are easier to install and keep up.
They give off a lot of heat while running quietly and without taking up any floor space.
In conclusion, both electric and hydronic baseboard heaters heat rooms well, but hydronic baseboard heaters use less energy than electric baseboard heaters.
When choosing a baseboard heater, it's important to think about things like how it's powered, how big it is, how much heat it can put out, and how energy efficient it is.
By giving these things careful thought, homeowners can choose a baseboard heater that will meet their heating needs and save them money and energy.
Energy Efficiency and Wiring of Baseboard Heaters
Energy Efficiency of Baseboard Heaters
Baseboard heaters usually use 250 watts per foot, so it's important to figure out how much energy a baseboard heater will use before buying one or making plans to use it.
One way to figure out how many watts a baseboard heater has is to measure its length in feet and multiply that number by 250.
Another way is to look for a label on the heater that says what kind of electricity it needs.
You can use a power consumption calculator to figure out how much electricity a baseboard heater uses over time, or you can multiply the wattage by the number of hours the heater will be on and divide by 1,000 to go from watts to kilowatts.
When shopping for a new electric baseboard heater or figuring out the heating capacity needed for a room addition or conversion project, the square footage of the room can be multiplied by 10 watts per square foot for moderate climates or up to 15 watts per square foot for colder climates to get the required heating capacity.
Wiring Baseboard Heaters
Turning off the power to the heater at the circuit breaker, mounting the thermostat on an inside wall at a height of 60 inches, routing the supply wire from the circuit breaker to the thermostat wiring box, connecting the ground wire from the circuit breaker to the ground wire going to the heater, and connecting a hot supply wire to one of the thermostat wires marked "L1" is all that is needed to wire a baseboard heater with a single pole thermostat.
Before doing any electrical work, you must turn off the power at the home's main electrical panel and use a voltage tester to make sure that no electricity is running through the wires.
Temperature Control of Baseboard Heaters
If a baseboard heater doesn't have a thermostat, you can still change the temperature or turn it off in a few different ways.
One easy way to do this is to use a thermostat that plugs into an electrical outlet and then into the baseboard heater.
Another choice is to use a thermostat that is hardwired to the heater and works with line voltage.
If you can't or don't want to install a thermostat, you can still change the temperature of a room by opening windows or doors to let cool air in or by using fans to move the air around.
Closing blinds or curtains can also help keep heat in.
Lastly, you can turn off the baseboard heater by unplugging it from the wall.
It's important to remember that this method shouldn't be used long-term, and if the heater is left on for a long time, it can cause a fire.
In the end, users can make better decisions about buying or using baseboard heaters if they know how much energy they use and how they are wired.
Controlling the temperature correctly is also important to save energy and keep people safe.
Troubleshooting and Efficiency of Baseboard Heaters
If your baseboard heater is giving you trouble, there are a few simple things you can do to find out what's wrong:
Check the thermostat to make sure it is set to the right temperature and is working properly.
If the thermostat doesn't work right, it might need to be changed.
Check the circuit breaker to make sure it hasn't been turned off.
If the circuit breaker has been tripped, reset it and see if the heater starts working again.
If the circuit breaker trips again, the heater may have an electrical problem that needs to be fixed by an expert.
- Check the heater element.
Use a multimeter to check the element's resistance and continuity.
This will help you figure out if the part is working right or needs to be replaced.
- Check for blockages: Make sure there are no things in the way of the heater's vents.
- Check the insulation: Make sure your home has enough insulation.
If your insulation isn't good, heat can escape and your heater won't work as well.
Efficiency of Baseboard Heaters
You can do the following to make sure that your baseboard heater is working well:
- Don't put furniture or other things in front of or on top of the heater or in the area around it.
This can stop air from moving and make the heater work less well.
- Use a programmable thermostat.
A programmable thermostat lets you set the temperature of your home based on your schedule.
This can help you save energy and cut down on the cost of heating your home.
- Use curtains and blinds.
Closing your curtains or blinds at night can help keep your home warm and stop heat loss.
- Install insulation.
Adding insulation to your home can help stop heat loss and reduce the amount of energy you need to heat your home.
By doing these easy things, you can make sure that your baseboard heater works well and efficiently.
If your heater is giving you trouble, it's always best to call a trained professional for help.

Use cases
| Used in: | Description: |
|---|---|
| Primary Heat: | Baseboard heaters might be the only way to heat a smaller house or apartment. They can be put in one room at a time or all over the house to provide a steady source of heat. |
| Heating by Zones: | Baseboard heaters can be used with a zoning system, which lets different rooms or areas of a building be heated separately from one another. This is especially helpful in big buildings where different rooms may have different heating needs, or in homes where some rooms are used more often than others. |
| Additions to Rooms: | When adding a new room to a home or building, it may not make sense to use the same heating system to heat the new room. In these cases, a baseboard heater can be put in the new room to add more heat without having to make major changes to the existing heating system. |
| Underground rooms and garages: | Basements and garages are often the coldest parts of a house or building, and they may not be connected to the central heating system. Baseboard heaters can be used in these areas to add extra heat, making them more comfortable and usable. |
| Rental Homes: | Baseboard heaters can be a cheap way to heat a vacation home or cabin that is only used during certain times of the year. They are a good way to keep a comfortable temperature without wasting energy because they can be turned on and off as needed. |
