Radiator valves are an essential component for maintaining an efficient and comfortable home heating system. These devices, including thermostatic radiator valves (TRVs), allow you to control the temperature of each radiator individually. By managing which rooms are heated and to what degree, you can create a warm, inviting space while improving energy efficiency and reducing heating costs.

Types of radiator valves

At Howarth, we offer a wide range of radiator valves to suit your needs, including:

Straight radiator valves: Perfect for piping that comes out of the floor, these valves connect directly to the radiator in a straight line, offering a clean and practical solution.

Angled radiator valves: A popular choice, angled valves connect at a 90-degree angle, helping to conceal pipework and create a tidy, seamless appearance.

Corner radiator valves: For a more aesthetic option, corner valves face inward toward the wall rather than adjacent to the radiator. They add a sleek, stylish touch to your heating setup.

Black radiator valves: A modern and sophisticated choice, black valves complement contemporary interiors and provide a bold contrast to lighter radiators.

Maintaining your radiator valves

Proper maintenance ensures your radiator valves remain efficient and functional. Regularly using a radiator bleed valve can help release trapped air, ensuring your heating system runs smoothly. If your valve is faulty or outdated, learning how to change a radiator valve or how to replace a radiator valve can restore optimal performance.

Why choose radiator thermostatic valves (TRVs)?

Radiator thermostatic valves are designed to automatically regulate the flow of hot water into the radiator based on the room’s temperature. This feature allows you to maintain a consistent level of comfort while saving energy by avoiding overheating.

Need assistance choosing the right radiator valve for your home? From angled and corner radiator valves to thermostatic options, our experts are here to guide you. Visit your local Howarth branch for personalized advice or explore our full range online.

Control your home’s heating with ease using high-quality radiator valves from Howarth.

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.
