A friend of mine bought a house that has two
water heaters. They were set up in parallel. I suggested
he try shutting one off. The only issue is that the house
also has a jacuzzi type tub. That takes all the hot water
to just get it to an acceptable level and is the reason for
the second water heater.


I can see the need filling that tub, but I have to wonder how often
that tub is really used and how much does it cost to keep that much
water on standby.

About 20 years ago, my wife and I stayed at a B&B that had one. Tried
it, was not impressed beyond that one time.
