Hi there,
I've been lurking about these forums for years but don't often post.
I'm about to embark upon an upgrade to my heating system to make it "smart" and a bit more efficient.
Currently I have a gravity hot water pumped central heating system with TRV's on all radiators except one (in the hall where the room stat is mounted).
Now I'm going to go full HR92 Honeywell TRV's on all 11 rads with wireless wifi controller and hot water kit.
I'm basically looking to fully zone my large house and create a C plan system at the same time.
My questions are.
1: Is the system "smart" enough not to require a bypass valve i.e. ensuring at least one valve is always open (and would I want this?). I'm pretty sure I can get decent access to the pipes coming off the boiler if I cut an access into a cupboard back wall to fit an automatic bypass valve before the first radiator.
2: I think I need a 28mm 2 port valve (Honeywell V4043H1106) to control the hot water side using the hot water wireless kit that will come with my Evohome system. But does it go in the flow or return pipework? The best access I have is to the upper pipe on the cylinder which tee's up to an overflow into the F&E tank and down to the boiler. The lower pipe which Tee's into the bottom of the F&E tank and the boiler would be very difficult to fit the valve into.
I might have more questions but I think that's the main two I have for now before I go order all my kit.
