    My new house has an old boiler system....the boiler in question is a Potterton Prima F, i would hazard a guess that it's really old. I've just recently bled the radiators in my house, but have not idea how to increase the pressure in my system. I tried to find a pressure gauge in the airing cupboard by the hot water tank, but can't seem to find anything that resembles a pressure gauge. Any suggestions?
     
  2. You have an open vent system, which means a header tank in the loft and water is let in via a ball valve in the header tank, no need to top up the pressure as it it isn't a pressurised system.

  5. Firstly make sure all valves are open and if yo have trv's check the pins aren't stuck (info in the faq's)
