Help!! I've just fitted two new radiators and had to drain the central heating system down to be able to do this. Now they are fitted and I have set the heating system back to how it was when I started (opened the gate valve and re-set the actuator to Auto) the hot water is not working.
The Boiler fires up for a minute then stops (and requires a reset) so I'm assuming it's not getting enough water to heat up? Any suggestions as to what I might do to fix this will be apprechiated :D
