Based on the excellent FAQ section, I think this might be a motorised valve failure, but would like some advice.
System, Worcester Oil based pumped system, 12 rads, oil fired boiler, E7 water heating, with Boiler top-up. Single Pump, 2 x motorised valves, one water, one central heating. CH timer set to 24/7 on, switched by Horstmann Electronic programmable thermostat.
Each morning CH set to turn on 06.00, off 08.30. Started not coming on at 06.00. If I turn off complete system, wait 2 mins and restart, all works OK.
Water boost always comes on straight away, so surely it must be motorised valve for C/H?
Any other thoughts/advice gratefully accepted.
Thanks
