Over the past few weeks, the boiler has not heated the water all the time. I've put more pressure into the boiler using the valve but this does not seem to work. The pilot light is on. When I run the tap slowly, sometimes the water is hot.
I'm stuck, please help.
The boiler is a Worchester Bosch 240
