A chap called me, sounds like an injun!
Has a megaflo, when water is run rads upstairs are getting hot.
It’s been going on a year
They’ve had plumbers who’ve changed trvs but not fixed.
Any ideas why?
I’m not going to look but I’d like to know what it could be with a fix.
Cheers all

the basic rule of heating has been breached, which is,,first tee from the boiler is the vent, next is the cold feed next is the pump then the 3 port, then the cylinder flow,, and the cylinder return must be the last back to the boiler, if that rule is broken, some rads will work, Attachment Deleted |
