Heat pump hot water cylinders are good. They save about 60 to 75% of your hot water heating expenses, and hot water can be two thirds of your electricity bill.

Solar is great but running pumps and fans can mount up. Do you maths on what a kilowatts hour costs and the price to run the various options.

Where I live gas is cheap but it winds me up (anoys the **** out of me) paying a dollar a day supply charge. Friends who don't mind it have califonts that heat the water as it's used and love it.

Getting back to the origonal subject; it would be nice to be extra insulated and have double glazed windows. They also hugely cut down noise.
