I’ve recently installed a Paloma tankless water heater for our master suite. It replaces a 40 gallon tank.
With just two of us living here, the 80 gallon tank for the other three bedrooms, the kitchen, and the laundry is unnecessary so I’d like to shut it down to save energy.
The two hot water systems are tied together so I can just open a valve and use the tankless for the whole house.
I’m looking for suggestions on how to “store” the 80 gallon tank. It is in the attic and the temperature ocassionally drops below freezing in Atlanta.
Thanks,
Mac

I would drain it and them cap it so that it does not get full of nasties.
Now if you leave it hooked up, but turned off, AND SO THAT WATER FLOWS THROUGH IT then it would be safe from a water quality point. But it can freeze.
If you leave it set with water in it that does not move then you have both the problems of freezing and "stuff" growing in it.
If you are talking about Atlanta Georgia I would seriously doubt anything would actually freeze in an attic. It would have to be very cold for a very long time. I live in Mobile and during the dead of winter I can go nekkid in the attic. Don't forget the water heater is insulated. I would deffinately drain anything of water that you intend not to use. Not worth the problems of something leaking through the ceiling.
