Turning off a baseboard heater is a piece of cake. Every baseboard heater comes with a turn on/off switch to turn the unit on or off. Alternatively, you can find a knob on the side of the heater to control the unit. 

But what if the turn on/off switch or the knob gets faulty? How to turn off baseboard heater then?

To avoid this problem, we will elaborate on multiple ways to turn off your baseboard heater. All of the turn-off systems are simple and effective. So, stay in tune with us till the end. 

How to Turn off Baseboard Heater [4 Easy Methods]

We will break down how to turn off your baseboard heater following 4 alternative methods. They are:

  • Turn off the heater with knob
  • Turn off the heater without knob
  • Turn off the heater with thermostat
  • Turn off the heater without a thermostat

Here we go….

1. Turn Off Baseboard Heater With Knob

Shutting your baseboard heater off is a breeze with the knob. Just set the knob to the Off position to turn off your baseboard heater. Then, unplug the unit from the electric outlet. 

The knob of your heater does not only help you to turn the baseboard heater on or off. You can also adjust the temperature. Rotate the knob to the lower setting to decrease temperature. To raise the temperature, just set the knob dial to a High position. 

2. Turn Off a Baseboard Heater Without Knob

How to turn off the baseboard heater if it doesn’t have a knob? Simple, you can shut down the baseboard heater by adjusting the thermostat. Just set the thermostat to its lowest settings or turn the thermostat to the off settings to turn off your baseboard heater. 

If you have an electric baseboard heater, there may be a wall-mounted thermostat to control the unit. Using the thermostat, you can easily turn on or off your electric baseboard heater. 

On the other hand, you can turn off the baseboard heater using the zone valve if you have a hot water baseboard heater. You can find the zone valve near the boiler. 

3. Turn Off Baseboard Heater with Thermostat

You can also turn off your baseboard heater using the thermostat. To shut off your heater, either set the thermostat to the lowest settings or set it to the off position. 

Therefore, the thermostat of your heater gives the stop command if the temperature crosses a certain level. Indeed, shutting off a heater with a thermostat is one of the easiest methods. 

4. Turn Off Baseboard Heater Without Thermostat

Though every baseboard heater features a thermostat, some heaters might not have the thermostat option. Alternatively, some baseboard heaters have a thermostat but do not have an off switch.

So, how to turn off the baseboard heater without a thermostat? In this case, you need to find out the boiler or furnace switch. Once you figure it out, turn it off to shut off your baseboard heater completely. 

Can I Turn off the Heat to One Room?

Most likely, you can’t turn off the baseboard heater in one room. Generally, the heating zones work as a big loop. So, you never turn the heater off for a single room without some sort of replumbing. 

The problem with replumbing is- you need to inspect the entire plumbing system because each situation is different. In this case, we recommend you hire a certified technician to take care of this issue. 

However, the scenario will be different if every room in your home has its own thermostat. In this case, you can reduce the temperature of a specific room by adjusting the thermostat. 

If you have a hot water baseboard, you can reduce the heat transfer by adjusting the damper on the baseboard housing. On the other hand, you need to install a switch to control the temperature on an electric baseboard. 


Are baseboard heaters always on?

No, baseboard heaters aren’t always on. You can turn it on and off according to your needs. 

How do I know if my baseboard heater is working?

Take a look at these three spots: The circuit breaker panel, the thermostat, and inside the heater. If everything is well in these places, understand your baseboard heater is working properly. But when there are issues with these three, you will find your baseboard heater is not working in a single room or everywhere of the baseboard.

Why is my heating still on when it’s turned off?

Your heater still produces heat though you turn the heater off if the check valve of the heater gets broken. 

How do you free a stuck diverter valve?

We recommend you get commercial cleaners for boilers to free a stuck diverter valve. 

Why does the thermostat not shut off?

Due to a faulty thermostat, the thermostat of your heater will not shut off. 


Throughout this guide, we discussed how to turn off the baseboard heater. 

Following the methods we mentioned above, you can effectively turn off your heater. However, any of the shut-off techniques we suggest don’t work, understand there might be a serious problem with your heating system.

So, it would be best to call a certified technician to solve the issue.

  1. Thanks for this!
    May I somehow remove the fins of a hydronic baseboard heater to reduce heat in a small room?

    The heating zone also heats a great room with cathedral ceilings…So the heat is always “on”, trying to heat the great room.

    But anyone sleeping in the small bedroom to the side of the great room gets overheated with the result of loss of sleep!

    I found two videos on YouTube demonstrating how to remove the fins when the copper pipe isn’t attached to the wall and you can simply hold it in your hands or lay it down on a workbench.

    But this won’t work for us, since we aren’t plumbers.

    Thanks for any insights to help!!
