The Hulthor Thermostatic Radiator Valve Head is an easy, tool-free upgrade for anyone looking to replace a worn-out or broken radiator control knob. Featuring a standard M30 x 1.5 connection, it fits directly onto Drayton TRV4 valve bodies and is compatible with most major UK radiator valve brands. Turn the dial to set your desired temperature anywhere between 7°C and 28°C. The thermostatic radiator head automatically regulates the flow of hot water through your radiator, opening when the room is cool and closing as it reaches the set temperature. This means more consistent comfort and lower heating bills. Installation takes seconds. Because you are only replacing the radiator thermostat head, there is no need to drain your central heating system or call a plumber. Simply remove your old head and clip the new Hulthor valve head into place. Every Hulthor TRV head is manufactured to meet the EN 215 European standard and pressure tested to 10 Bar. The integrated frost protection setting safeguards your pipes when the house is unoccupied during winter. Whether you are upgrading a single radiator or replacing thermostatic radiator valve heads throughout your home, the Hulthor TRV head delivers precise temperature control in a compact, stylish chrome and white design.
