This is in a first floor flat (i.e. water has to travel up one story from mains). When turning on the hot tap, the burner light clicks on and the boiler 'sounds' as though it is working. It will stay on for up to about 10 seconds and then click off - as though a pre-requisite for heating water has not been satisfied. This may happen many times until eventually the boiler stays on and heats the water correctly. In some cases, it has continually clicked on/off for about 20 minutes (wasting water...) before I've given up.
An engineer has visited before and mentioned that it was due to water pressure coming up from the mains. Water company checked and said that wasn't the case.
The pressure on the boiler (I believe, not next to the unit right now) is normally around 1.5 / 2 bar.
With experience, it seems the lower the flow rate out of the hot tap, the more likely I am to get hot water.
I wonder if anyone has any advice before we have to call an engineer out again.
Cheers,
Chris
