dreamerb, thanks for the reply. I can easily get gas and always have a spare bottle. But bottled gas is a very expensive way of getting gas into our homes. I have read that it can be five or six times more expensive per unit that electricity. That would be a significant difference over the life of an oven. hence my initial inquiry.
Does anybody know how much bottled gas is per unit for oven cooking, say roasting a turkey for five hours on 180? What would be the difference for an electric oven and a bottle gas oven?
