The system losses water pressure intermittantly (according to the gauge on the boiler) although it seems to be getting more pronounced, I have to top up the pressure twice or more times a day now. It seems to be worse when only dhw is drawn.There does not seem to be any leaks in the sytem.Please has anyone any sugestions?

I have exactly the same problem and would be very grateful if you could say whether you got a reply to your question?
Thanks
