Pressure on Worcester Heatslave 20/25

[richard3009]

The water pressure on my Worcester Heatslave 20/25 is at just over 2 bar is this above normal operating pressure, secondly I have a couple of upstairs rads that will not seem to bleed they are only warm at the bottom quarter, more problems to follow but that's enough for now.

Thanks in advance

Bit high - Pressure will be stated on your instructions (would expect it to be about 1.5 bar). Bear in mind that all liquids expand when heated so the reading will vary depending on how hot the system is and whether the central heating is on.

Sounds like your rads will need balancing. Google "radiator balancing" for descriptions on how to do it.
