Hi,
I've been having issues with my heating which looks to be caused by poor flow around the system, see the previous thread;
https://www.diynot.com/diy/threads/...-radiators-not-heating-up-fully.531129/page-3
I had a gas safe registered company come in to take a look who suggested a low loss header, which I was already think of suggesting and he was supposed to come to carry out the works last week however his electrician has let him down, meaning that he can't carry out the works, or the controls side.
Luckily I own my own engineering company and we carry out both electrical and controls works so I have offered to carry out this bit myself, if he is okay with that, which he is but he has said that he can offer no help on this because he simply doesn't know. This is the reason for my post on here. I'm hoping there is some one on here that can offer some advice as to how this should be set up.
I've spoken with valiant technical this morning and he sent me the below image of how my boiler needs to be wired but to me this isn't quite correct because it only shows the one pump.
I have a Valiant 637 Ecotec boiler and a hot water cylinder. I have three zone valves, upstairs heating, downstairs heating and DHW.
We want to have an individual pump feeding each one of these zones. I already have a room stat for upstairs and one for downstairs.
I know that i will need a wiring centre for this to work but unsure if that is the VR70 or VR700, if there's a difference and then a wiring diagram that is correct to my application.
Can any one help?
