Log Burner Socket.

A new free standing 5kW multi-fuel log burner is to be installed in a corer of a bungalow. The walls are timber and plasterboard internally. A double socket has been banked off with a blanking plate onto a flush metal box. How far from the log burner side must it be distanced please?

  • how hot the walls get varies widely with surface finish. Something  shiny that reflects the heat will not be anything like as bad as a region painted matt black. Ours has cream painted solid masonry walls, in closest places about 4 inches away, and they get too hot to touch but not to sizzle a wet finger, so I suspect 50-60 C.

    Low down is better - our burner is raised a foot or so, on a shelf, as firewood is stored  beneath it, and the space beneath is kept cool by the air drawn in to replace the hot stuff going up the chimney.

    If the socket  is to be used while the wood burner is on, think about what for - a white single plug may be OK a foot away,  but a black bodied phone charger of the kind that already runs a bit close to the limit thermally may fail prematurely.  Also you do not want the user to trail the flex over the burner (well no, but some folk might) Ideally you want to interrupt the line ‘sight’ for the  direct IR radiation if you can.
