Help! We are in a freezing cold house, it's -10 outside and we do not have access to warm water. Today, tomorrow and after tomorrow are holidays here in Austria and we cannot get external help...

The issue is simple, I tried to Bleed Out a heater and let too much water out.
The pressure on my heater says 0.0 Bar right now.

I cannot let water in again because there are no valves as there usually is on Youtube videos and other forums. I attached the pictures to the pipes under the heater, please help!

    You need to find out where the water MU goes into the boiler and why it is not feeding.

    The alternative to that is to use city water from a hose bib or sink and run a garden hose to the system and fill it to 1 bar through the hose. isolate and detach the hose when complete. Make sure the boiler is shut down and don't feed water into a really hot boiler.

    SOLVED:

    For those who have the same model. The two golden screws can be opened (Very slowly and carefully) to let new water pressure in. The one on the left needs to be opened especially slowly until you can hear the sound of the water coming in.

    @EBEBRATT-Ed thank you so much for writing!
