Hi,
Vokera Compaxt 24.
Engineer changed Heat Exchanger today as old one had crack causing pressure in CH system to rise.
However, the Thermostat in the Hallway is constantly calling for heat as I set the target temp to 23 degrees, and it's not getting over 19.5 degrees. Plus there is a little triangle on the display to signal it is calling for heat.
The boiler on the other hand seems to cycle on and off, NOT really very frequently, such as every 2 mins, it seems to be a good 20 mins to half an hour before it turns off for a few minutes, then comes back on. However, in this period of downtime the radiators cool off a little, and the thermostat is struggling to rise above 20 degrees. Heating has been on for a few hours now. All radiators get nice and hot whilst the boiler is running.
My question is should the boiler cycle on and off if there is a constant call for heat from the thermostat? Or does this suggest a potential issue.
The engineer who changed the Heat Exchanger seems to think that it is normal behaviour.
Hot water seems fine, behaves as it always did. When you first turn shower on it gets hot then goes cold for a few seconds before going hot again and staying hot.... although I'm not sure that is right either!
Regards
Kevin
