How To Change Baseboard Heaters

Baseboard heaters act as silent, unnoticed employees. They perform a terrific job of heating the house despite not being seen from the outside. But when should baseboard heaters be updated? How do you accomplish this?

Baseboard heaters can be updated by cleaning the old filter and installing a new one. A better ventilation system can be provided by updating in your home. The steps are as follows:

  • Offset the power.
  • Take the cover off.
  • Baseboard heaters should be cleaned.
  • Replace the filter.
  • Examine the heater.

More information regarding baseboard heaters will be included in this article, along with a step-by-step tutorial for replacing them. We’ll go over their operation and how it affects the HVAC system.

Regarding Changing Baseboard Heaters

How To Change Baseboard Heaters

By dispersing heated air across the space, baseboard heaters raise the temperature. In order to save space, they are typically positioned between the wall and the floor. Updating them is a smart method to improve your climate control.

See the processes for updating baseboard heaters below:

1. Switch The Power Off

The main power supply should be turned off, and a sign warning people not to turn it back on until the heater has been updated, should be placed. The baseboard heater includes numerous metallic fins that carry electricity, so keep that in mind.

While you have access to the house wires, now is a good time to check the wiring for safety to prevent heating short circuits.

Recheck the wires, then use electrical tape to cover any exposed areas. To evaluate any sophisticated wiring, you might need to speak with an electrician.

2. Eliminate The Cover

Unfasten the screws from their sockets with a screwdriver to release the covers. On both ends are a number of cables and power connectors, and in the center are several lengthy metallic fins. Later, we’ll talk about the purpose of these fins.

3. Keep Baseboard Heaters Clean

How To Change Baseboard Heaters

Avoid getting any liquid, including water, on the metal fins. Instead, dry clean everything but the cover, which you may wash with water and a cleaning solution. Cleaning is included in replacing the baseboard heaters because it would be absurd to skip this step.

To clean the baseboards, get ready these tools:

Vacuum Cleaner
Use a vacuum to quickly remove dirt.

Gentle Brush
To get rid of the dust in between the fins, a little brush works well.

Cleaning Solution
The cover may be cleaned with water and dish soap.

Dry Fabric
To rub the cover, you’ll need a dry cloth.

The following procedures should be followed to clean baseboard heaters:

  • Wash the cover in a different sink using water and dish soap. It should be wiped dry before being put aside.
  • Use a vacuum to remove the debris from in between the fins.
  • Clean the heater of any last traces of filth.
  • Reuse the vacuum to completely remove the dirt.
  • Do not yet replace the cover. A new filter needs to be installed first.

4. Replace The Filter

Depending on the manufacturer, there are filters made to fit into baseboard heaters. To improve the airflow and prevent corrosion of the heater, you can replace the filter.

To get a sense of how your baseboard heater can appear, glance at the example below. Replacing the filter will make the heater look better. Additionally, you can alter the cover to suit your preferred design.

You can install the new filter by following these general instructions:

  • Place the new filter around the fin and on the mount bracket.
  • Screwing the filter against the wall to secure it in position
  • Place the new filter around the fin and on the mount bracket.
  • Screwing the filter against the wall secures it in place.
  • Recover the cover. A replacement that is quite similar to the one you previously used may also be installed.

5. A Heater Test

You can now test the heater after completing these update steps, including cleaning and filter replacement. When the electricity is turned on, you should notice an improvement in the temperature. For a few days, keep an eye on how the air quality changes.

What Are Baseboard Heaters’ Mechanisms?

Knowing how baseboard heaters operate is useful. In addition to providing comfort for you, they support the other ventilation networks. For instance, the room next to yours has a ceiling fan. Both rooms warm up more quickly since the heat can spread more quickly.

After a short period of time, the metallic fins become heated as a result of electricity passing through them. Since baseboard heaters lack fans, the heat will be distributed evenly throughout the space. When the thermostat reaches the desired temperature, the heater will shut off on its own.

It’s best to inspect the heater frequently, though. If it doesn’t get a signal from the thermostat, it can keep blowing hot air.

Establish a timetable for when to turn on the heater, such as while you’re gone, to prevent overheating.

After Updating The Heater, Should You Replace The Thermostat As Well?

The thermostat need not be replaced unless it is broken. However, it might be useful to reset it.

The thermostat needs to be reset in order for it to work correctly with the heater. Simply switch the thermostat on and off, then after a few minutes, set it to the preferred temperature.

How Durable Are Baseboard Heaters?

A typical baseboard heater has a 25-year lifespan. By cleaning it at least once every four months, you can extend its lifespan.

Baseboard Heater Types

Identifying these heaters’ properties is essential for updating them. If you prefer certain baseboard heater types over your current heater, you can think about switching. These kinds are listed below:

Convection Heaters
A convection heater’s job is to warm the air by spreading heat across the entire space by gathering cool air drafts from the floor.

This baseboard heater is also the most popular. The heat may not be retained by its fins for a long time after the heater has been turned off. Electricity should be kept on until the appropriate temperature is reached because convection heaters also rely on it.

Hydronic Heaters
Hydronic heaters have a longer warm-up time than convection heaters—up to a few hours after the power is switched off. This is so that the liquid contained in the reservoir of a hydronic heater, which is typically a solution of glycol and water, can boil when the heater is turned on.

Due to the boiling process, a hydronic heater may take longer to heat up, but it may also be more effective at spreading heat throughout the space.

Where Can Baseboard Heaters Be Installed?

Remember that a heater that is placed correctly will be effective. See the list of rooms in your house where baseboard heaters can be installed below.

In Between The Glass Walls
Glass walls are effective insulators and influence the temperature of a space. To keep the rain from entering, the glass walls should be sealed.

Wall Angles
The heater can be placed in the corner to conserve room and to assist the heat travel more quickly by making contact with two walls as opposed to just one. To prevent damage, your furniture must be at least three feet away from the heater.

Can Baseboard Heaters Be Moved?

The baseboard heater can be moved, but it can take some time, work, and preparation. Perhaps you want to rearrange the furnishings to make more room.

Before you may move the baseboard heater, a specialist must inspect the wires. You could, however, refer to these actions:

Before you may move the baseboard heater, a specialist must inspect the wires. You could, however, refer to these actions:

  • Unscrew the cap after shutting off the power supply.
  • Follow the wires that lead to the primary source.
  • To release these wires, twist the knots.
  • Pull the heater away from the wall with a crowbar.
  • Install the heater where you intend to move it.
  • The power source’s lines should be reconnected.


We’ve talked about how to clean and replace filters to upgrade your baseboard heater. Depending on the needs of your home, you can also think about switching to a different kind of heater.

You now understand how and where to install baseboard heaters. In case you need to organize your home and save additional room, we also gave instructions for moving the heaters.
