    GAH Electrastream boiler, low pressure level, how to top up system?

    Can anyone help me identify which tap/connection it is to top up the system as the level has dropped quite a way below the red marker for the cold fill pressure on the gauge? Boiler was installed approx. 2014. I've looked in the manual & online but can't find anything. Many thanks

    How do I Increase Pressure in my boiler??

    Hi, I am trying to increase the pressure in my gas boiler and was under the assumption it just involved opening these two small black valves. I have tried this but the pressure gauge on the boiler hasn't budged? Anyone know why this is?

    I was told by the plumber to keep an eye on the pressure, to ensure it stays above 1.0. The red one is… but the black one is not…. What do the two mean?
