You control a radiator thermostat by turning the valve to your desired setting, which regulates the flow of hot water into the radiator and, therefore, the heat it emits. Think of it like adjusting the tap on a hot water faucet.
Here's a breakdown of how radiator thermostats work:
-
The Basics: Radiator thermostats, also known as Thermostatic Radiator Valves (TRVs), are designed to control the temperature of individual rooms by adjusting the amount of hot water flowing into the radiator.
-
How They Work:
- Turning the Valve: The core principle is that turning the valve adjusts the opening through which hot water flows from your boiler to the radiator.
- Higher Setting = More Heat: A higher setting on the valve allows more hot water to enter the radiator, resulting in more heat output.
- Lower Setting = Less Heat: Conversely, a lower setting restricts the flow of hot water, reducing the radiator's heat output.
-
Temperature Settings: Most TRVs have numbered settings (e.g., 1-5 or * to 5) rather than specific temperature readings. These numbers represent levels of heat, not exact temperatures in degrees Celsius or Fahrenheit. Some modern smart TRVs display the actual set temperature.
-
Optimal Usage:
- Adjust to Comfort: Experiment with the settings to find the comfort level for each room.
- Avoid Covering: Ensure the TRV isn't covered by curtains or furniture, as this can lead to inaccurate temperature readings and inefficient heating.
- Balance Heating: Use TRVs to balance the heating throughout your home. You might set them higher in rooms you use more frequently and lower in less-used areas.
-
Example: Imagine you want a room to be warmer. You would turn the TRV to a higher number (e.g., from 2 to 4). This allows more hot water into the radiator, increasing the room's temperature. If the room becomes too warm, you'd turn the valve down to a lower setting.
In essence, controlling a radiator thermostat involves manually adjusting the valve to regulate the hot water flow and achieve the desired temperature in a specific room.
