I can fill my boiler to 1.5 bar and the following day the gauge reads zero. The central heating still works and there is no obvius leak. Anybody any ideas?
check your pressure release valve or also check your expansion vessel has pressure in it and that no water is comeing out of the valve on it when depressed

GET A HEATING ENGINEER TO CHECK THAT THE PRESSURE VALVE IS WORKING .IT COULD BE THAT YOUR GAUGE IS BROKE.

There is some leak as it is loosing pressure check pressurevalve, rads valves or under floorboard, water has to go some where. if you keep topping up everyday than your system will form rust inside and more problem soon
