I have to replace and reposition a radiator in my sons house.

Customer Question

I have to replace and reposition a radiator in my sons house. There is a vented cold water galvanised tank in loft which supplies domestic hot water through a cylinder but no sign of separate supply and expansion tank. I am assuming therefore he has a system boiler which has its own expansion chamber and pump. If so how do I turn off water supply to drain radiators and when I refill is there anything I need to do?

Customer:

Hi . the heating system water is sealed and will not fill itself back up . when you drain the system froM the drain valve ,open the top radiator bleed valve to help drain the system

Customer:

When filling back up , shut all radiator bleeds and then fill the system up using the filling loop.
