Thanks very much! With the help of your picture I managed to get the pressure back to normal levels!
Unfortunately this hasn't fixed the problem! The hot water works fine but the heating still won't come on. I thought the low (zero reading) pressure was the problem. It must be something else!
Thanks for taking the time to help.
