Zoning of heating system up stairs and down

[Patchie]

Hi all, I have been told by a firm I some times do work for that we all have to put the up stairs and down stairs heating on two x two ports and stats, which in most cases is not that hard but if down stairs rads are on drops you would have to run two circuits around up stairs. Any help will be just that.

Thanks

In every house?? I thought they had to be a certain size?

the worcester bosch technical bulletin explains it well. but in brief every dwelling unless its single storey open planned.

no body seems to bother with it tho from what i can see. Local authority by me dont bother, only seen it on new build as a standard spec.

Mainly been doing new builds with under floor which is then on separate zones any way or with towel rail circuits etc, I must have missed the memo on that then! I do beleive that if its over 150m2 you have to have it on separate time clocks as well. Thanks

with new builds it depends on the date of planning permission.

This was discussed in an earlier topic - see http://www.ukplumbersforums.co.uk/c...-heating-zones-new-replacement-systems-4.html . The OP couldn't get a sensible answer from his BCO so he contacted the DCLG as they are the responsible government department. He received the following reply (see rodders post dated 10-8-12 on page 4):

When simply replacing a boiler, there is no requirement to upgrade the whole heating system to meet current standards. In general it is only the component being replaced that needs to comply.

It is only heating systems in new dwellings and complete new heating systems (including pipework) in existing dwellings that should be provided with two heating zones - and then only if cost-effective.

On new builds you can get round it using TRVs with built in time clocks, but of course the rads only come on when the main circuit is on.
