If you are wondering how to turn on a radiator, don’t worry; it is a relatively simple process that can be completed in a few short steps. However, given that there are several different types of radiators, some variation exists in the way the process is executed.
For instance, there are manual radiators that must be turned on and off by hand and thermostatic radiator valves (TRVs) that are more autonomous. In the case of the latter, the radiator will only turn on when the temperature in the room drops below a certain level, which is set by the user. This can be useful for saving energy, as the radiator will not be constantly running when it is not needed.
Additionally, most radiators have a dial or knob that can be turned to adjust the temperature. Turning the dial or knob clockwise will increase the temperature, while turning it counterclockwise will decrease the temperature. Finally, there are electric radiators that are plugged into an electrical outlet. These radiators are typically used in rooms that do not have central heating, and they can be turned on and off with a switch or remote control.
Identifying the Radiator’s Design
Valve Design
Radiators typically feature one or more valves that control the flow of hot water from the central heating system. These valves can vary in design, with common types including:
*
- Manual Radiator Valves: Require manual adjustment using a knob or handle to open or close the valve. They provide precise control over the heat output of the radiator.
- Thermostatic Radiator Valves (TRVs): Automatically adjust the flow of hot water based on the desired room temperature. They feature a temperature sensor that triggers the valve to open or close as needed to maintain the set temperature.
- Smart Radiator Valves (SRVs): Offer advanced functionality such as remote control, scheduling, and temperature monitoring through a mobile app or home automation system. They provide enhanced energy efficiency and comfort.
Types of Radiators
| Type | Characteristics |
|---|---|
| Convector Radiators | Comprise metal fins arranged in a vertical or horizontal orientation. Hot water circulates through the fins, heating the air that rises through them. |
| Panel Radiators | Consist of flat metal panels welded together. Hot water flows through internal channels, warming the panels and radiating heat into the room. |
| Towel Rails | Similar to panel radiators but designed specifically for heating and drying towels. They often feature additional bars or hooks for towel placement. |
| Column Radiators | Made up of interconnected vertical columns, allowing for a larger surface area to emit heat. |
Additional Features
Some radiators may include additional features, such as:
- Built-in bleed valves for releasing trapped air.
- Adjustable feet for leveling the radiator.
- Finishes or coverings to match the room’s décor.
Setting the Desired Temperature
Once you’ve turned on the radiator, it’s time to set the desired temperature. This will depend on your personal preferences and the size of your room. A good starting point is to set the thermostat to a medium setting, around 68 degrees Fahrenheit (20 degrees Celsius). You can then adjust the temperature up or down as needed.
Here’s a more detailed guide to setting the desired temperature:
- Identify the thermostat knob or dial. This will usually be located on the side or front of the radiator.
- Turn the knob or dial to the desired setting. The higher the number, the warmer the temperature will be.
- Wait for the radiator to adjust. It may take a few minutes for the radiator to reach the desired temperature.
- Check the temperature and adjust as needed. Use a thermometer to check the temperature of the room and make adjustments to the thermostat as needed.
- Set a timer (optional). If you want to save energy, you can set a timer on the thermostat to turn the radiator off automatically after a certain period of time.
| Temperature Setting | Recommended Room Size |
|---|---|
| 60-65°F (15-18°C) | Bedrooms, bathrooms |
| 68-72°F (20-22°C) | Living rooms, dining rooms |
| 75-80°F (24-27°C) | Kitchens, laundry rooms |
Turning the Radiator Completely Off
To turn off your radiator completely, follow these steps:
1. Locate the TRV
The TRV (thermostatic radiator valve) is usually located at the bottom of the radiator, where the pipe enters. It will have a dial or digital display that shows the desired temperature.
2. Turn the TRV to the lowest setting
Most TRVs have a numbered scale, with 1 being the lowest setting. Turn the dial or press the down button until the TRV reaches 1.
3. Turn off the lock shield valve
The lock shield valve is usually located on the other end of the radiator, where the pipe exits. It will have a small handle or cap. Turn the handle or cap clockwise to close the valve.
If your radiator has a thermostatic radiator valve, you can skip steps 1 and 2, and proceed directly to step 3.
4. Check if the radiator is off
Once you have completed steps 1-3, check if the radiator is off by placing your hand on it. It should feel cool to the touch.
5. Bleed the radiator if necessary
If the radiator is still warm after you have turned it off, it may need to be bled. To bleed the radiator, place a container under the bleed valve (usually located at the top of the radiator) and open the valve slightly using a bleed key. Close the valve once water starts to come out of the radiator.
6. Insulate the radiator
To improve the efficiency of your radiator, you can insulate it by wrapping it in radiator foil or by placing a radiator cover over it.
7. Use smart thermostats or radiator controls
Smart thermostats and radiator controls allow you to automate the temperature control of your radiators. This can help you save energy and reduce your heating bills.

How to Turn a Radiator On and Off
Radiators are a common way to heat homes and businesses. They work by circulating hot water through metal tubes, which transfer heat to the surrounding air. Radiators can be turned on and off manually or with a thermostat.
To turn on a radiator manually, simply open the valve that controls the flow of hot water into the radiator. The valve is usually located at the bottom of the radiator, and it can be turned by hand or with a wrench. Once the valve is open, the radiator will begin to fill with hot water and start to heat up.
To turn off a radiator manually, simply close the valve that controls the flow of hot water into the radiator. The radiator will then stop filling with hot water and will gradually cool down.
If your radiator is equipped with a thermostat, you can use the thermostat to turn the radiator on and off automatically. The thermostat will sense the temperature of the surrounding air and will turn the radiator on when the temperature drops below the desired setting. The thermostat will turn the radiator off when the temperature rises above the desired setting.
People Also Ask About How to Turn a Radiator On and Off
How do I know if my radiator is on or off?
You can tell if your radiator is on or off by feeling the surface of the radiator. If the radiator is on, the surface will be warm to the touch. If the radiator is off, the surface will be cool to the touch.
Why is my radiator not getting hot?
There are a few reasons why your radiator might not be getting hot. One possibility is that the valve that controls the flow of hot water into the radiator is closed. Another possibility is that there is air trapped in the radiator, which is preventing the hot water from circulating properly. You can release the air from the radiator by opening the bleed valve, which is usually located at the top of the radiator.
How do I clean a radiator?
To clean a radiator, you will need to remove the dust and dirt that has accumulated on the surface of the radiator. You can do this with a vacuum cleaner or a damp cloth. You should also clean the inside of the radiator by flushing it with water. To flush the radiator, simply open the drain valve at the bottom of the radiator and allow the water to run until it is clear.
