Been using Tiny Titan 2.5 gallon hot water heaters at point of use for 17 years. Had one in Baton Rouge underneath the kitchen sink. Have 5 here: 1. main kitchen sink, 2. basement kitchen sink, 3. laundry room, 4. carriage house, 5. pool equipment area for slop sink and outside shower.
They withstand being outside and not emptied as far as any freeze effects, as long as the water is off and depressurized.
Lowes and Home Depot carry them. Price has been going up though, to now slightly higher than a 50 gallon tank.
