Underfloor heating problem

[Davidgreer]

Hi, I'm a new poster but need a bit of help.

any idea how I can raise the temperature of the water here? I presume this is why my heating isn't working very well.

When did It stop working? Usually turn blue knob towards floor, listen when system is on and you will hear a pitch change as different (hot water blends. More likely to be the bypass is open or one of the two port valves has died. Are any pipes hot? Where is heat coming from looks like you have a plate exchanger ? Is that hot ( silver ripply thing

Thank for replying, it is working, but I don't it's as good as it should be. I was told the temperature on the gauge should be higher. Also I think the boiler cuts in a lot. It's a 900sq apartment btw. The pipes are sort of lukewarm, the plate exchanger is hot yes. The blue knob appears to be at Max?

Take off the blue head and you may be able to increase temp then
Btw your pressure is to high it's nearly at 3 bar

Turn to max and remove knob, remove knob, turn it to min in air then out it back on , turn to max again.

What time periods do you have it on for?

I couldn't remove the blue knob, it's got a screw in it and it's awkwardly positioned.

I have the timers heating up to 22 in the morning for a couple of hours, dropped to 18, then going back to 22 in the evening.

What at temperature should this be showing?

Thanks.

Try using an angled screwdriver such as Draper 2 Piece Plain Slot & Pozi Type Angled Screwdriver Set : Tooled-Up.com

You will need the air separator, fitted to the top of the manifolds as I'm sure that is "contraflow" pipe. It is like rubber hose with no oxygen barrier. Sucks air in like a good un. Very prone to sludge.
