How to release pressure in underfloor heating

    Happy new year all. My underfloor heating was off for a few days, has been working fine. Naturally when it was off for a while I increased the bar pressure but I may have increased it too much :( Now when the underfloor is back on it quickly goes over 3 and water starts leaking (see attached). What/where can I go to release the pressure a bit?

    Any suggestions?

    Hm, turning the red valve on the top right of the large water tank sprays water out and in doing so releases pressure. Is that what I'm meant to do? Doing so let me bring it down to 1.5 bar

    Yes that'll release the pressure but usually when you open them valves, they're fecked. Dry the outlet of that valve and make sure it stays dry. If not you'll need to replace it.

    Evening all. Having some issues still with the boiler (little or no heat and now the unit is beeping with some generic error messages).

    I wonder have I screwed up the valves, I can't remember if I've turned the wrong way l, I really should write this stuff down. Here's the two valves in question, I *think* it's a return pipe. I'm pretty sure the red handle is ok, the black thing is turned counter clockwise ... Seem ok?
