    1 CAN SET THE SYSTEM PRESSURE TO 1-BAR AND THEN REMOVE THE FILLING LOOP. EVERYTHING WOKS OK WITH BOTH THE HEATING AND DOMESTIC HOT WATER. OVER THE NEXT 4 TO 6 HOURS THE SYSTEM PRESSURE WILL RISE TO ABOUT 3-BAR. I WILL THEN RELEASE WATER FROM THE SYSTEM UNTILL IT IS BACK TO 1-BAR AND THE PROCESS STARTS OVER AGAIN. WHEN IT REACHES 3-BAR I WILL RELEASE SOME WATER AND SO ON. IF I ISOLATE THE COLD WATER FEED TO THE BOILER THEN OBVIOUSLY THE PRESSURE REMAINS CONSTANT. COULD IT BE A PROBLEM WITH THE DOMESTIC HOT WATER HEAT EXCHANGE UNIT ?. I WOULD BE VERY GRATEFULL IF ANYONE COULD HELP ME OUT WITH THIS PROBLEM. MANY THANKS ANTHONY MARCH.
