Hi,
I'm looking to fit a hearth so that a wood burner can be installed inside a chimney breast recess. I've been reading the regulations regarding hearth thickness and I'm a little confused.
The hearth I'm looking to fit would be 90mm total thickness and installed inside the chimney recess extending onto the suspended timber floor joists and ledger plate which is fixed into the chimney breast. The suspended timber floor is the living floor above the basement in a Victorian house. The original hearth and joists were renewed as the joists ends of the entire floor were rotten and a total replacement was necessary. A ledger plate was installed onto the chimney breast to take the joist ends instead of a trimmer joist as I understood only a low heat 12mm hearth minimum was necessary with a burner that doesn't heat the hearth above 100 degrees. The wood burner being installed is a Burley 9104 which meets this requirement.
I've read conflicting information about the hearth thickness as I've seen some recommendations that if a burner is installed inside a recess a constructional hearth is needed. Is this correct? My only thinking is that this is in case the fire is converted back to an open fireplace in the future? The 90mm hearth I'm looking to install exceeds the 12mm low heat hearth by quite some margin.
Any advice would be appreciated.
Thanks,
Pete
