How to pressure a worcester heatslave 20/25 ?

[boulanger]

Hello,
I am french and I bought a house in France where the english owners who renovated the house installed a worcester system whereas this firm is not represented at all in France, and the plumbiers don't know unfortunately this system. I need help because I can't located and understand the operations to do in order to fill up the pressure. The system is working very well but the pressure is only 0.3 bars, I am worrying quite a lot... If you can help with video or photos, that would be a must. Thank you very much !

You need to find something that looks like that ^^^ Turn the handle(s) and you should hear water running, when the pressure gauge is between 1 -1.5 bar close the handles. It is good practice to disconnect the hose and place the caps over the valves (if caps are provided).

Thank you for your answer, but unfortunately there is no mixer tap.

Maybe internal loop;

Maybe Snowy, but this is an oil boiler (discontinued in 2007).

To the OP, Are you sure it's a sealed system? You may have an open vent system.

Thank you, but this is not this system.

As I asked previously, are you SURE it's a sealed system? Have a look in your roofspace. If there's a small, 5 gallon, tank up there, it's open vent.

Otherwise, have a look for a pressure vessel, it'll look like a red metal balloon, you'll more than likely find your fill loop (as pictured above) attached to it or nearby.
