I need to ask what is essentially a know, or don't know in my case, question:
During the process of fitting an S plan heating system, is it a legal requirement under the building regs to fit an ABV or can you leave a rad in the presently on position? If so, where does the ABV get fitted - I'm thinking that it's after the pump but before the zone valves but I'm not certain at the moment and I'm not at the job right now.
I ask because I've already converted the old system when I changed the boiler and I didn't realise that this might be a legal requirement at the time.
if I have to fit the ABV (In this position) then I have to make alterations that will cost me and while I realise that it might be a lesson learned I still would like to know in any case.
The system uses a Trianco Eurostar 100/125 external oil boiler, two Honeywell 2 port zone valves, and a Honeywell RF2 wireless control pack with room/cylinder stats.
needless to say that as my design skills are still a little rusty, all advice (sensible) is appreciated.
