I have a 1910 villa and a Vietnamese wife with a new born. She has been here for 14 years but still likes it warm.

I'm working on getting her to understand that we don't need to heat rooms we don't use.

But $280 is cheaper than I pay during summer. I'm averaging about 20KWHs in the summer. At the moment it's closer to 75KWHs per day. Our hot water is all gas. About 1 x $150 bottle per month in the summer. That moves up to 1 per week in the winter.

Double glassing is in the wish list. Then wall insulation. But we have a mortgage and an asbestos roof to deal with first.
