So, what is boiler short cycling?

Boilers rely on reading the temperature from thermostats in different rooms, as well as the internal thermostat in the boiler itself. When a boiler is short cycling, it is detecting the temperature of the water in the heat exchanger, and because it has cooled while the heating system has been off, it powers up to heat that water back to the ‘correct temperature’. This can be happening even when your heating doesn’t need to be switched on, and because it only takes a short amount of time to heat the water to the right temperature, it tends to happen quickly and frequently.

What causes boiler short cycling?

Boiler short cycling can be caused by a number of factors, including;

  • Using a boiler that is too large for your home- a boiler that is too powerful for the demand your home puts on it will likely fire up and turn off more frequently.
  • A broken thermostat- a thermostat is designed to measure the temperature in a room, triggering the heating system to come on when the temperature drops below a specified temperature. If a thermostat isn’t reading the temperature accurately, then it could cause the boiler to cycle on and off more than is needed or more than usual.

What issues does a boiler short cycling cause?

If your boiler is frequently short cycling, this can cause a number of issues, including:

  • A more expensive energy bill
  • More frequent issues and faults with your boiler
  • Needing to replace your boiler earlier than necessary
