We had the above boiler fitted in a one bedroom, first floor flat. It took 13 hours to install, but we were generally happy at the result. Until yesterday, when the pressure was down at 0.6 bar and we had no hot water and heating. I decided to bleed in some mains water and the pressure jumped to over 1 bar. I had some concern over this so called the installers who told me that it was probably caused by air in the system and to bleed the radiators. I bled the radiarors for about 5 mins each, then switched the heating on (because I was cold) and the pressure jumped to 3.2 bar, something it hadn't done at all the previous week.Any advice would be (GREATLY) appreciated.
