Insulation and unvented

[justlead1]

While fitting a new unvented cylinder for a client. A building control officer made an appearance and was adamant that lagging of all pipes withing a metre of the cylinder needed to be insulated / lagged. In order to get me up to speed on the subjects. Has any one come across this practice? Is it a new requirement?

Had it before over here, apparently to stop custards burning themselves in their hotpresses. Then the custards complain because the hot press ain't as hot as it was!

Lag it in tubelite, custard can take it off easier then!

Remember that from college which was just over 2 years ago so could be fairly recent. Not seen anyone do it however.

We have to do it all the time on new build, its a NHBC requirement and also a BC requirement.

I think its standard practice on virtually every new build. Personally I think its a load of rubbish you either lag it all or not bother!

Thats been the case since 2002 for building regs
Not just unvented , all cylinders.

Thank for replies. Going green is one thing but walking about with damp cloths and sleeping on damp sheets cant be the way forward.

Its a requirement of Part L of building regs and is to do with standing heatloss of the cylinder
