Boiler Cycling (Gloworm Economy +)

[jg1975]

Hi can anyone provide a bit of knowledge on this one? Please.

I have recently moved house and, i have now turned on the heating, the boiler fires up and warms radiators to required temperature. At this point the boiler just continually cycles.

Once temperure is achieved,it fires up it stays ignited for approx 10 secs max before switching off. Then approx 10 secs later reignites for another 10 secs. and cuts out. and again and again

I have increased the speed setting on the pump and this has no effect.

This system is very basic only with TRVs but no room thermostats!! could this explain the continual cycling?

Any ideas or common faults with this boiler which could explain the symptoms???

Many Thanks

like you say no room stat. it is working off the boiler stat. so it will keep comming on/off.
