Re: Incredibly inefficient - not
"I'm confused. Are you saying that in Britain it's common to heat a house with a kitchen stove?"
No, we don't. In some circumstances, they might still do that but they are either years old (there's really nothing in them the break) or are bought by people with a big kitchen and plenty of cash mainly for a bit of that Olde Worlde look. A bit like those of you in the colonies who still like the old fashioned 1950's look refrigerator or other kitchen appliances.
But wait! You have a whole furnace to heat your house? What is it? A 10 bedroom mansion? Do you employ your own stoker to shovel the coal in?
Most people in the UK have a fairly small gas powered combi boiler that does heating and "instant" hot water that's about the size of a medium suit case.
