Radiator valves

(46)

Thermostatic radiator valves (TRV) consist of two parts: a sensor and a valve. The sensor monitors room temperature and adjusts the valve in order to control the flow of hot water to the radiator. If it’s too cold, it increases the flow, and if it’s too hot it shuts it off. Read More

Most TRVs are set manually, although they can also be controlled digitally. Their key benefit is reduced energy costs: the radiator is only on if the room temperature falls below the designated level.

Separate thermostat heads are also available. Some have remote sensors, allowing the room temperature to be monitored at a distance from the radiator.

Unlike TRVs, which are termed 'set and forget' valves, manual radiator valves need to be continually turned up or down if a constant temperature is to be maintained.

The likelihood that someone forgets to turn a valve down if a room is too warm or not being used is the main reason for their relative energy inefficiency.

Their major advantage is that they are smaller, and the distinct aesthetic that contemporary or retro versions give is not compromised by the thermostat.

Lockshield valves are used to balance central heating systems. They also allow individual radiators to be shut off for maintenance without affecting the rest of the system.
