Hi,
This is my first time here so I apologise if this topic has been discussed already. I have a Powermax 155 combi boiler with an open vented primary system for central heating and a sealed hot water system. (As you can guess I'm no plumber)
I have recently changed my radiator valves and have had to drain and refill the heating system. Now it sounds as if the water is having to be constantly topped up at the cistern and also there are strange noises from within some of the rad's. I have bled all the rad'a but the instruction manual says to bleed the pump but I cannot see where you can do this as there are no obvious bleed screws.
Also the system seems not to get as hot as before, would this be due to air in the system also?
Can anyone advise!!!
Thank you
Casper76.
