Hello
My Greenstar CDi boiler goes into Siphon Fill mode multiple times a day for 15 minutes at a time - this means that there is a 15 min lag between the thermostat clicking on and the boiler leaving the siphon fill mode and kicking in and heat returning to the radiators.
Im looking for a steer on whether the boiler being in siphon fill mode so often is normal or an error ?
I have had an engineer in a couple of times - first time he changed the sensor in the boiler and now he wants to change the thermostat.
Thanks Mia
