I would like to install a wood-burning stove in front of an old
fireplace but the constructional hearth is not deep enough to provide
the required 300mm clearance in front of the stove.
would it be sufficient to build a superimposed hearth on top of the old
hearth and some of the (suspended) floor ?

if this is allowed/safe then I would ideally like a raised and tiled
hearth, so what material could be used to provide a strong and
heatproof structure under the tiles ?

Hope that made sense
Thanks in advance for any replies

Superimposed hearths over combustable materials (which is what you're
proposing) are allowed, but the Building Regulations specify is some
detail what is permitted.

Simply putting a hearth on to of the wooden boards would not be
permitted unless it was very thick, or had a substantial airgap
incorporated, or was a type of stove that had been approved as not
causing excessive heating underneath.


You might find it easier to remove some of the suspended floor and
extend the constructional hearth.

More than that, you need 500mm under the floor and 300mm above.

looks like there is an easy 12mm option if hearth temp 100 deg and
after a quick search found that charnwood certify their stoves for this
- so think Ill go for that and save myself some work.

thanks for the link
