What To Know

  • The first step in turning off a radiator heater is to locate the valve that controls its flow of hot water.
  • To bleed the radiator, place a container underneath the bleed valve, which is usually located at the top of the radiator.
  • To drain the radiator, open the bleed valve and drain cock, which is usually located at the bottom of the radiator.

In the chilly winter months, radiator heaters provide a cozy and efficient way to warm up your home. However, when the temperature starts to rise or you’re leaving for an extended period, it’s important to know how to turn off your radiator heater properly. This guide will walk you through the simple steps involved, ensuring comfort and energy savings.

Identifying the Radiator Heater Valve

The first step in turning off a radiator heater is to locate the valve that controls its flow of hot water. This valve is typically situated on one end of the radiator, either at the top or bottom. It may be a small knob, lever, or screw-like mechanism.

Turning Off the Valve

Once you have located the valve, turn it clockwise to shut off the flow of hot water into the radiator. You should feel some resistance as you turn the valve, and it will eventually reach a point where it cannot be turned any further.

Bleeding the Radiator (Optional)

If you hear any gurgling or hissing sounds coming from the radiator after turning off the valve, it may indicate that there is air trapped inside. To release this air, you will need to bleed the radiator.

To bleed the radiator, place a container underneath the bleed valve, which is usually located at the top of the radiator. Use a radiator key or a flat-head screwdriver to open the bleed valve slightly. You should hear the air escaping and see water dripping into the container. Close the bleed valve once the water starts to flow steadily.

Closing the Thermostat

If your radiator heater has a thermostat, it’s important to turn it off as well. This will prevent the heater from turning on again when the room temperature drops.

Turning Off the Main Water Supply (Optional)

If you’re going to be away from home for an extended period, it’s a good idea to turn off the main water supply to your home. This will prevent any water leaks from occurring while you’re away.

Draining the Radiator (Optional)

If you’re planning to store your radiator during the summer months, it’s a good idea to drain the water from it to prevent corrosion. To drain the radiator, open the bleed valve and drain cock, which is usually located at the bottom of the radiator.

Turning off your radiator heater is a simple process that can help you save energy and maintain the comfort of your home. By following the steps outlined in this guide, you can ensure that your radiator heater is turned off properly and efficiently.
