I am building a home and am deciding on the hot water source. Our home will
most likely be all electric. I was pretty fixed on a tankless water heater
(electric) but a friend has two newer and efficient tank heaters with a
timer to allow heating only at night when electric rates are much cheaper.
So now I am no so sure. Any wisdom that could be spared is welcome.
It depends upon the electrical and gas costs for your area... For most
people, gas is cheaper... If you want to have an outdoor gas grill,
it's nice to have natural gas available and not have to resort to 20
lb tanks of LPG... Personally, I would suggest that if gas is
available, have it installed... I prefer a gas range to an electric
one... My current house has a gas range, but an electric oven... Good
enough, I guess since it only gets used for making garlic toast and
the occasional batch of frozen chocolate chip cookies... One major
advantage of gas is that during periods of severe storms, it is
significantly more likely to stay on than electricity... Being located
on the Gulf Coast, that's a significant concern for me...
Does such a thing even exist for a whole house? It would take one hell
of a lot of current to heat water instantly to supply anywhere near the
simultaneous worse case demands of a house. Also, it was indicated
that the electric rates are cheaper for off peak water heating.
Usually they are significantly less and that is likely the deciding
factor which would make an electric tank type the best choice.
