Product Description
Thermostatic Radiator Valve TRV and Lockshiled Chrome Plated Brass Body White HeadA
thermostatic radiator valve (
TRV) is a self-regulating
valve fitted to hot
water heating system
radiator, to control the temperature of a room by changing the flow of hot water to the radiator.
FunctionConventional wax motor TRV
The classic thermostatic radiator valve contains a plug, typically made of wax (forming a wax motor), which expands or contracts with the surrounding temperature. This plug is connected to a pin which in turn is connected to a valve. The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot water entering the radiator. This allows a maximum temperature to be set for each room.
As the valve works by sensing the temperature of the air surrounding it, it is important to ensure that it is not covered by material (such as curtains). If the controller is removed from the valve, the valve turns on and the radiator will always be hot.
Interaction with room thermostats
Thermostatic radiator valve should not be installed in the same room where the room (air temperature) thermostat is installed. This is because in the case that the TRV set temperature is below the room thermostat set temperature, the TRV would shut off the radiator before the latter temperature is reached. The central heating boiler would continue to run in an attempt to reach the room thermostat set temperature, potentially heating the rest of the house to uncomfortably high levels if TRVs are not installed on the radiators in every room. If both TRV and thermostat set temperatures were set equally, unpredictable behaviour may occur with both devices attempting to control the room temperature. Therefore, in case of installing a TRV and an air temperature based boiler thermostat in the same room, the TRV should be set to a higher temperature than the room thermostat.
Compared to manual control
The replacement of a manual heating control with a conventional wax motor TRV has been estimated to save at least 280 kilograms (620 lb) of CO2 per year (in 2011 for a British semi-detached house with 3 bedrooms and gas heating[1]). They are also considerably cost-efficient, using heat only when needed, and can reduce heating bills by up to 17 percent a year.[2]
Electronically controlled variants
As of 2012, electronically controlled TRVs have become more common, and some of these are marketed as smart thermostats or even smart TRVs. They frequently use electronic temperature sensing, and can often be programmed or remote-controlled so that individual radiators in a house can be programmed for different temperatures at different times of the day, or automatically respond to occupancy and occupancy patterns. Such increased control allows more advanced controls, which can result in even better energy and CO2 savings.[3] Some other possibilities with such systems is that the temperature sensor can be placed away from the radiator in another place in the room, which may result in a more relevant temperature reading in the room which can be used to set the TRVs operating point. Some electronically controlled valves run on batteries which must be changed at regular intervals, while others can be connected to the power grid. Electronically controlled variants may also require additional setup, for example by connecting to a mobile phone application through a smart home hub using wireless protocols such as Zigbee or Z-Wave.
