Thermostatic radiator valves (TRVs)

Thermostatic radiator valves, or TRVs, are a simple, energy-efficient way to control the temperature in individual rooms of your home. Designed to regulate heat output automatically based on the ambient temperature of the room, these self-regulating valves help you maintain comfort while reducing energy waste.

At BestHeating, we stock an impressive selection of TRVs in a range of finishes and styles to complement both modern and traditional radiators and interiors. Whether you're upgrading your system or adding the finishing touches to a new installation, our TRVs offer both form and function at an affordable price.

How Do Thermostatic Radiator Valves Work?

TRVs use a heat-sensitive element that expands and contracts to control the flow of hot water into your radiator. When the room reaches your desired temperature, the valve automatically adjusts to maintain it – giving you effortless temperature control without the need to adjust your boiler or thermostat.

This helps prevent rooms from overheating, especially in spaces that naturally get warmer throughout the day - like rooms with south-facing windows.

Why should you choose TRVs?

• Energy saving – Reduce your heating bills by using less energy in rooms that don’t need it.
• Room-by-room control – Set different temperatures in different spaces.
• Automatic regulation – TRVs self-adjust based on the room’s heat level.
• Stylish finishes – From chrome to brushed brass, matt black and more, you will find the perfect match for your radiator.

Where Should You Use TRVs?

TRVs can be installed on most radiators, but they’re best suited to living areas, bedrooms, and other spaces where heat needs to be adjusted throughout the day. Avoid fitting TRVs in bathrooms, as the steam can interfere with the valve's sensor and cause inaccurate readings.
