    Hi everyone, if anybody is out there that can give a little help would be great. I’m going from domestic plumbing into house bashing end of the month now I’ve been told the heating on new builds is zoned off even on combi boilers. Could anybody just shine some light on how to pipe this system up. The zone valves would be in a cupboard upstairs. Thanks.

    As far as I am aware it is on above a certain square footage?

    Hey thanks for the reply, I wouldn’t know as I haven’t started yet just I got speaking briefly to a guy about it and he said down stairs and upstairs now have to be zoned off. If you are right about the square footage how would this system be piped!?

    I’ve done some small 2 bed houses recently( new builds) and initially wasn’t to sure myself, so I contacted the architect and he says now ‘All properties regardless of size must have upstairs/ downstairs zoned’

    House size upto 150m2 only require trvs, house size over 150m2 require at least 2 heating zones

    What don’t you understand about piping it?? Surely you’ve come across s plan arrangements doing domestic plumbing? It’s very similar

    Second paragraph down, ‘every home must be divided into at least two zones’

    Do you have any qualifications as a heating engineer? The fact you don't seem to be familar with the current Building Regulations and are asking an internet forum such a general question means you are taking on a big risk by also trying to design the system yourself. Your contract from the developer should include a detailed specification of the work they want done, including a drawing of pipe sizes and runs, methods and materials statements, etc. You need to check this against current regs and query anything that doesn't seem right to you.

    Hi thanks for the reply, I’ve been plumbing for 6 years with a company doing general plumbing underfloor heating and one off new builds just want to try out site work for something different. I haven’t had any drawings as yet as I haven’t started yet was just asking about to see what it’s like. Thanks

    if controlled by the same controller what’s the point of the zones?(future extensions maybe?)

    Same controller but 2 thermostats, so the heating came on upstairs and downstairs at the same time but controllable at 2 different temp settings
