Re: True Sloane Range-r
We used to have a cheap Aga-like oven in the house where I grew up, although this was a solid fuel (ie wood and coal) fired one. During the winter we had to keep it burning constantly, because it was the only source of heat in the whole house, even in the UK, there's a risk of freezing to death if you have no heating during a cold snap.
There's also another use for an Aga that no one has mentioned. They typically have several doors, opening on compartments at different temperatures, one of which is around 30-40C (I guess it's supposed to be for warming one's plates or somesuch). Farmers use this to incubate lambs that have been abandoned by their mothers. Maybe you own a jumper that started it's life snuggled inside an Aga?
