Hi,
When i turn on a hot tap the boiler supplies DHW, but at the same time the central heating circuit starts getting hot too.
For example if the bathroom shower is used for 5-10 mins the upstairs radiators get hot.
Also the central heating circuit (supposed to be sealed i believe) is losing pressure to the point where i have to top it up every couple of days.
To top it off last week the boiler sounded like it was running continuously when there was no CH or DHW demand for a fair while. I checked it out and the CH pressure gauge was reading just over 3 bar... So i drained some water out of the drain point on a downstairs rad.
Any ideas why?
