My system is about a year old. I had to bleed my up stairs radiators last night as there was a lot of air in them. This morning the heating would not kick in. Hot water is fine. I noticed the presssure was down so have increased it to about 1.5 bars but the heating system will still not fire up. The termostat is up and displays it is working. I have reset the system 3-4 times. Each time I reset the digital display goes down from 60 to 38 at around 41 the system acts as if it is going to start working but as it start to climb back up it all shuts down again. I'm a women and blond at that so may be that's why I don't understand. Please help... the kids and I are very cold...please... ;0(
