Ours was converted from solid fuel to oil. No part of it requires separate heat sources. Once the Aga is on, every part of it is heated by the same heat source. Giant lids, which are unbelievably heavy, can be drawn down over the hot plates to stop heat wastage.
Right, so now were getting somewhere, Jane!
You're saying if the Aga wasn't on that night then the rifle barrel could not have been heated up on the top plates, right??
Yet the rifle was not hot enough to inflict the burns without being heated up for five minutes on the plate in the Boyce experiments, and there was no other heat source in the house.
Hence the Aga must have been on if the rifle burned Nevills back,
