A thermostatic radiator valve is a type of radiator valve which is self-regulating, controlling the temperature of a room by altering the levels of hot water which are delivered to the radiator. Once the TRV is set to the desired level, the valve automatically controls the heat output from the radiator. Set them to the level you want for the room; a lower setting uses less energy and so will save you money. They should not be confused with boiler controls. Rooms with manual (on/off) radiator controls set to “on” will continue to heat up until the boiler switches off again. TRVs work by controlling the flow of hot water into radiators. A thermostatic radiator valve (TRV) is made up of two parts. So how do these valves actually work? There are manual valves and thermostatic valves. If you have thermostatic radiator valves, make sure that they are set so that your home heats evenly when your Nest Thermostat is at the temperature you like. Danfoss radiator thermostats maintain constant desired room temperatures, individually room by room and help to reduce energy consumption. A thermostatic radiator valve on position 2 (15-17 °C). TRVs consist of two main parts, a Thermostatic Head which senses the air temperature around them and the valve body, which together regulate the flow of water through the radiator which they are fitted to. A thermostatic radiator valve is as easy to fit as a manual valve, it simply offers more control of the heating in that location. The distance between the valve seat and the valve cone determine how much water is flowing through the valve and to the radiator. Section of a thermostatic radiator valve. Once you've set the temperature, the thermostat is supposed to switch the heating on and off, as necessary, to keep the room more or less that warm. Thermostatic taps for baths work in the same way as thermostatic showers; water just comes out of a tap rather than a shower head. Exclusive gas-filled design: Our design uses an exclusive gas fill, which reacts faster to changing temperatures than other designs. This type of radiator thermostat enables you to personalise your temperatures in every room. How does a TRV work?

When Heat On Demand turns the heating on, every radiator will be provided with heat. The classic TRV contains a wax plug which expands or contracts according to the temperature of the air around it. In fact, the Energy Saving Trust says that a home using these valves alongside a thermostat could save £75 per year.. How do smart radiator valves work? Traditional Radiator Valves – How Do They Work? TRVs work by controlling the flow of hot water into radiators. If choosing between manual and TRVs, TRVs are generally recommended because of the far greater heating control they provide. Nearly all radiators are fitted with valves and they are nearly always fitted at the bottom of the radiator, at opposite ends. A radiator thermostat is a modulating control that allows proportionally more flow for a greater demand, and less flow for smaller demand, thus controlling the amount of heat available to be emitted by the radiator. Globe valves and angle valves are commonly used as construction forms. When used correctly, these valves can help to reduce the amount of energy and heat … Now the most common type of radiator to be installed in the UK, thermostatic radiator valves offer the user a level of flexibility that makes it easy for the user to have a space heated just how they like it. There is an indirect link - TRVs control the temperature of each room, and therefore have an effect on the temperature that's sensed by the wall thermostat. The TRV is a self-regulating valve that works by changing the flow of hot water into a radiator. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes. They sense the air temperature in the room. This plug is connected to a pin, and this pin is connected to a valve; as the air temperature gradually increases, the wax gradually expands, and the valve gradually closes, which in turn limits the amount of hot water which enters the radiator and effectively turns down the output of the radiator. Thermostatic radiator valves, TRV's, have a sensor in the head of the valve which senses the temperature of the air around them and reacts by either opening or closing the radiator valve accordingly.
