But they are usually but not always electric which can be a cost issue in some areas.
I have been searching for the so called "Worlds Most Efficient Water Heater" I saw last year for a while, blast why don't I bookmark everything.
Anyway it only lost 1deg per week and it could be heated with any source you wanted be it solar, electric or gas.
Anyone remember that one?
