Radiator valves, also known as thermostatic radiator valves (TRV’s), are an easy way to control the temperature of each of your radiators separately. This allows you to regulate which areas are kept warm and to what temperature, as well as choosing which areas don’t need to be heated. It will allow you more control over the temperature in each room of your house, therefore creating a warm and inviting space that is more efficient and cost-effective.

We offer many different types of radiator valves at Howarth, such as straight valves, which are often used to run along the wall straight into the radiator valve. They are best used for piping that comes out of the floor rather than the wall. Angled valves are one of the most common radiator valves, which connect at a 90-degree angle to your radiator. This means that they present a neater look, as the valve is connected from behind the unit itself. Corner valves are a more aesthetic alternative to the angled valve, as they face inwards towards the wall opposed to facing adjacent to the heating unit. The corner valve gives your radiator a little more shine and is certainly worth the installation.

For further information and expert advice about which radiator valve would be best for your home, please contact your friendly local Howarth branch.

Frequently Asked Questions

How do I change a radiator valve?

To change a radiator valve, you will need to first switch off the heating and water system, and then locate the drain off. After that, you will need to remove the old radiator valve to be able to fit the new radiator valve. That is when you can turn the mains water back on, to be able to finish by bleeding the radiator.

How do thermostatic radiator valves work?

Thermostatic valve head goes on top of the valve body, and then as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes.

What are the two valves on a radiator for?

One of the valves accounts for hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.

What side of the radiator is the lockshield valve?

The lockshield valve is located on the side of the radiator opposite the on/off valve.

How to change a radiator valve without draining the system?

To change a radiator valve without draining the whole system, start by turning the heating and water off, then protect the floor around the radiator under the valves to catch any excess water. After that, prepare the radiator valves by removing the nuts and adaptors on the new valve and smear it with the PFTE tape that joins to the radiator. Next, release the stored pressure, then open the old valve on the flow pipe. Once the thermostatic valve or manual is open, release the pressure, drain the radiator and remove the old thermostatic valve. Finally, you can attach the new thermostatic valve or manual valve, remove the old lockshield valve, and connect the new lockshield valve to finish.
