Hi,
As I am replacing my furnace to high efficiency furnace, I am considering buying new water heater (natural gas). My house is not to tight, so powervented is not a requirement, although an option. Could anyone recommend brand/model for most efficient heater? Same salesmen told me to switch to powervented one, but I was told that per year I'll save about 6$ ! Another saving will be that heat in my home will not go through the chimney... I checked home depot and they had 3 regular natural gas water heaters and one power vented water heater. Home depot guy was not able to explain much about them...
Thanks
