Zoning a living room in bungalow with combi boiler

[steveafoss]

Looking for practical advice please!
I have just done a complete central heating install with a combi boiler in a bungalow and believed that as a single storey it would be classed as a single zone. Just had my Gas Inspection and have been told I still have to zone the living room. All rads are fitted with TRV's. The living room has 2 rads (L-shaped room). Does anyone have any idea as to the cheapest and easiest way of correcting this. I have not yet installed the thermostat (customer wants a wireless thermostat which I haven't yet bought).

Any help gratefully listened to!

It depends on the current layout of your pipes, would be hard to give an accurate answer without knowing that.
Ideally you'd zone from a T at the start of the F/R pipework, not sure if a zoned bypass of just the living room rads would be any use other than to exclude the living room. The inspector would want it possible to heat the living room only as one of the zones so you're probably going to be lifting a fair few boards again I'm afraid

Why does the gas safety inspection encroach onto a building regs query? GSR don't police the building regs do they?

All pipework in loft including boiler the bunglow is less then 150 m2 so i thought it didnt need zoning but after wading through pages & pages online found i was wrong so trying to sort lucky for me bunglow empty for another 3 weeks

Using programmable trvs might get round this - you can get them for about £25

Just read in this months Gas Engineer (issue 37) page 13 in the section HAVE YOUR SAY BEFORE BUILDING REGS CHANGE 1/2 way through the article "DCLG has proposed to revert back to the 2008 requirements for space heat zoning by permitting a single thermostat and TRVs to be used in a domestic property with a floor area below 150m2 as to the current requirements of 2 thermostats and zoning". This is how i have fitted at the moment till Mr Gas Safe Inspector told me its to be zoned and is coming back to check in 6 weeks (property is 110.5 m2). So it seems i am going to alter the pipe work, then 6 months down the line need not have bothered. I can understand the need for zoning on a large property but wish they could get there act together to decide on a smaller property.
