Thermostats, timers and programmers explained
- 1. What is a timer?
A boiler timer allows very basic timing functions to be set on your central heating. They generally only allow one timing pattern to be set, so all days would have the same timings for heating and hot water.
- 2. What is a thermostat?
A room thermostat is a wall mounted device that detects the ambient of the home and allows the user to set the central heating to a specific temperature. The optimum location for these devices are hallways and landings rather than rooms that can be isolated by the closure of doors. They should be positioned away from obstructions.
- 3. What is a Programmer?
A boiler programmer is a device that allows a user to set the time the heating and hot water is needed. Programmers allow different patterns to be set according to each day, so week days may have different requirements to the weekends for example.
- 4. What is a thermostatic radiator valve (TRV)?
Known as a TRV, a thermostatic radiator valve is a self regulating valve. It works by sensing the individual room temperature, adjusting accordingly and shutting off the radiator when the desired temperature is reached. By fitting one to each radiator, you can easily control the temperature in each room, which helps to improve comfort in your home and save money and energy. They are recommended by the government and Energy Saving Trust as they are energy efficient.
Ideally, TRVs should be well exposed and not obstructed by curtains or blocked by furniture.
