Hi all.
Need to change a 3port valve, i know how to etc, but I don't understand this system. It's a bit of a hash up in the airing cupboard,
thought it looked like a atandard gravity feed system with f and e,
But then I looked at the boiler which has an expansion vessel and what not.
What kind of boiler/system is this? How do I isolate and drain The system (not tank)? Also when fitting the electrics do I need to reprogram the system?
Cheers
Edd
