I thought I would post in case it helps anyone else in the future.
I've posted a couple of times on our on-going heating problem - basically the radiators would only get warm (very occasionally they would get hot). The controller was still calling for heat and the relay light was on, the boiler would run for about 5 minutes and then boiler and pump would switch off. We never achieved the required temperature.
After ruling out the pump and the boiler thermostat, it turned out to be the motorised valve sticking which we have now replaced. This morning husband had to get up, turn off heating and open window as we were too hot!
Thanks to everybody who answered my posts and gave advice. I really appreciate the time people will take to help out.
