Zone valves on a domestic system?

[Macca2011]

Hi everyone, I am going to quote a customer for a central heating installation. In discussion with my gas man who will be installing and commissioning the new boiler (if we get the job lol) He has informed me that there is a new building regulation regarding the installation of zone valves on all new central heating installs. Apparently you now need to fit two room stats, one up stairs and one downstairs. This he was told by a inspector from gas safe. Has anyone else heard of this new reg? I have googled it but can't find anything.

Many thanks

what's that in English? does it means 2 separate room stats? 150m2 is approximately what size house? my god why do they complicate things

150m2 is approximately what size house?

About a four bed modern house. Easy to work out roughly. Measure your outside walls, pace it if you like. 9m x 7m = 63 x 2 stories = 126m2

All houses should be zoned now IMO no matter the size upstairs downstairs and hot water only at a minimum

is this easy to do, fitting the zone valves, what about pipe work?

It is easy to do on a new install but not so easy to do on existing stuff.
