Air gap for wood burning stove

Post by landroverman » Tue Jan 15, 2019 8:26 am

Can anyone help, going to install a wood burner in my house, it's a timber stud with a natural stone skin, my question is how close can the stove be to the plasterboard if I put cement board behind the stove with a 25mm air gap to the plasterboard ? The stove I'm looking at has a 300mm to combustibles clearance . Thanks in advance

It's supposed to be installed by a HETAS engineer (and certified etc) all according to part J of the Building Regs

which has all the information you need.

other choices are apply via the building control route "BEFORE YOU START"
they will tell you exactly what they expect
this will most likely be to install with a class 1 liner to the standards off part "J"
https://www.gov.uk/government/publicati ... document-j
you will both have to pay for there services and for the setup to be checked and passed
there are loads off cheap woodburners on ebay because when people find the cost involved is far far greater than just the burner they just sell them

Thanks for the replies so far, my issue is not with the flue/chimney as I will be installing 1000mm twin wall directly from the top of the stove then 45 out thought the wall which is perfectly fine, it is the distance of the stove to the internal wall is the issue, and I can't seem to find any advice on that, I have fitted stoves in the past into stone built cottages that have passed heatas inspection before so I'm no novice just in my part of the world qualified people are like hens teeth and know how to charge !

ISTR something like 300mm spacing but Part J tells it all.

what does the installation instructions say as these tend to be more definitive than part j

Quite right - Part J specifies the minimum, the manufacturers may well state differently.
