Boiler controls explained, best boilers heating controls

Heating controls: Boiler, room, cylinder thermostats & timer

Your boiler and central heating system are fitted with a variety of controls, allowing you to manage temperatures, timings and energy consumption. There are different kinds of boiler controls, same as there are different types of boilers.

 

Boiler thermostat

The boiler thermostat controls the temperature of the water that flows through your system and feeds your radiators, and the temperature of your tap water. You can adjust this temperature according to your needs.

The LOW or MIN setting (approximately 50°C) is more energy efficient and is the ideal setting for the warmer, summer months. Additionally, because the water isn’t too hot, there’s no risk of scalding when using your hot water taps, or if you accidentally touch a radiator or pipe.

The HIGH or MAX setting (80°C+) burns more energy, but ensures that your radiators can heat up quickly and keep your home warm during the colder, winter months. While it also means that your hot water will run to temperature even in colder weather, you need to be aware of burn risks.

 

Room thermostat

Usually placed in your hallway or landing, the room thermostat has a built-in air temperature sensor which regulates the overall heat levels in your home. Setting your room thermostat at 18-20°C should keep you comfortable without wasting energy; when your home reaches this temperature, the sensor will send a message to your boiler, telling it to switch off until the temperature drops and it needs to fire up again to raise the temperature to the defined level.

 

Cylinder thermostat 

If you have a separate hot water cylinder, this controls the temperature inside, working in the same way as the room thermostat.

This thermostat should be set at around 60- 65°C, in order to bust bacteria but stay safe for skin!

 

Timer/programmer

Your timer switch, with its built-in clock and electronic display, allows you to set your heating (and hot water if you don’t have an ‘on-demand’ system) to come on and switch off at selected times throughout the day.

More sophisticated models also allow you to adjust your settings according to the day of the week too.
