Hi all, I thought I had a great solution to heating water. needless to say the 1st attempt at this battery powered water heater failed, and I need to rework it. in the meantime, If I give them water at 7 a.m. and again at 6 p.m. Will that be ok? I figure the water will take a bit to freeze, so say it freezes by 9 or 10 a.m., they'll at least get a good drink in the morning. then have to wait until I get back from work. Will they be ok with this arrangement? I pretty much have no choice with the complications I ran into. Thanks!
