More on previous post: CH - Thank you...
Have read the faq on CH sealed systems. Interesting and entertaining!
"Shirely" an installer wouldn't do such awkard things.
(Hears Da's voice: "I could have done better with the spanner up me a£$%)
Anyway all my improvements, zone valves, F&V and OSV, pump, are by the
chimney breast where the BBU is situated.
If we go for a new boiler (standard or condensing, floor or wall) could I
site the boiler remote from my handiwork and just run two new flow and
return pipes to connect to the existing system?
