    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?

    HETAS - Without a pressure pump

    Hi all, Just a quick question. I have a log burner and a gas boiler on a dual fuel system (Central heating and Hot Water) either can do both.

    Hi, guys! Hope you are all well. I have four solenoid valves connected to the main water supply, and they seem to break quite often. I believe it's the pressure that's causing this.

    What is the pressure in this cylinder expansion vessel?

    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?
