If you take a closer look at the radiators in your home, you’ll notice a small knob with numbers on it, known as a thermostatic radiator valve (TRV). You might be surprised to learn that these numbers don't actually correspond to the temperature of the radiator. Instead, it refers to something else completely. Nathan Martin-Nicholls, a plumber at INHOUSE Plumbing and Heating, provided a helpful explanation to clear up the confusion. He said: “The numbers actually relate to the temperature in the room, not the temperature of the radiator.” This means the thermostat valve works to track the temperature of the room rather than regulating how hot the radiator itself gets. As we move past the coldest months of winter, who would have thought we’ve been using the radiator incorrectly?.
A TRV detects the room’s temperature and controls the flow of hot water into the radiator. When the room is colder, it allows more hot water to flow, increasing the radiator’s warmth. On the other hand, when the room reaches the desired temperature, it reduces the amount of hot water flowing into the radiator. The numbers on the TVR roughly correspond to the temperature of the room. For example:.
In an another interview with the Sun, Nathan also mentioned: "TRVs are a simple way to give you full temperature control on radiators in any rooms where you have the TRVs installed. The main benefit to them is that they will save you money on your heating bills, if you use them correctly.". Given the rising costs of heating bills, especially during the colder months, this tip comes in handy. In fact, heating bill experts have shared tips for getting the most out of your radiators while keeping energy costs under control. For example, it’s important not to cover the radiators with curtains or clothes, as this can block the flow of heat into the room.
