Will those in the southern states cope? Could you switch?

another system that was heating up a big tank of water all the time for no reason
Shouldn’t a larger system be, in at least some ways, more efficient? Since volume scales by r^3 and surface area by r^(2), a larger tank loses less of its heat to the environment.

I guess it’s efficient in heating up a certain amount of water but the problem is that it was heating up far more water than I was ever using. The insulation of the tank keeps it warm to an extent, but the massive cut in gas usage suggests it was doing a lot of heating for nothing. The new one is efficient in the sense that it only heats what I need and has cut my gas usage.
