I have a Ferroli Tempra Boiler. It works fine other than when

Customer Question

I have a Ferroli Tempra Boiler. It works fine other than when it reaches temperature it switches off for 20 seconds and then fires up again for 35 seconds. This sequence carries on all the time. We have just moved into this house so I don't know how long the boiler has been like this. Maybe the internal thermostat but would be grateful for any advice.

Hi , it most likely is the Central heating flow limit thermostat that needs replacing. Relatively cheap and easy to do
