Hi all!
I'm a new homeowner in a new build that's been fitted with a Danfoss series 7 HIU. We've had no problem with the hot water since moving in in the early summer and I thought it was time to check the heating before it got too cold!
Low and behold....the radiators won't heat up. Thermostat is fine so I did some torubleshooting and am pretty sure the system isn't sufficiently pressurised.
It's currently reading 0.5 where everything I can see online says it needs to be 1.5 to 2 ideally and that the system won't activate below this.
I've been desperately trying to find how to fill the system to the correct pressure and came across this thread:
Frustratingly the photos have expired so I can't see where the filling loop is and how to access it!
Any help would be much appreciated!
Thanks

Danfoss HIU Filling Loop
Hi, hoping someone out there can help.We have a Danfoss HIU. The pressure is down and have been told to fill the system. I've connected everything as shown in the pics but the gauge isn't budging. [/IMG]
