Hi,
My CH zone valve actuator gave up the ghost today... Getting a replacement tomorrow...
Whilst removing the dead actuator, I realised that my system has 2 x 2 port valves (1 for CH, 1 for HW) whereas in my last home an otherwise identical system had 1 3-port. Not a problem, just a realisation/observation...!
So my question is, what are the merits of 2 port valves vs 3 port valve ? (other than a 3 port can feed 2 things not just 1 .. I get that bit!)
As well as pure curiousity, there's a practical reason for the question as I'm hoping to zone the CH 3 floors of my home separately, as opposed to 1 zone fits-all (inefficiently). My assumption is that I'm best doing this with 3 x 2port valves (1 per floor) in parallel with a 4th one for the HW cylinder coil. (Wiring to activate valves providing the control)
Ta!
