For those who lose power to their water heater gets a trick we used for almost three weeks after hurricane Wilma in South Florida.
Connect all your garden hoses and find a spot in the yard that gets good sun. Lay the hose flat on the ground in concentric circles upon itself as you would nicely coil a boat line on the dock so it’s not a trip step. Run water through it with any kind of shut off at the end. Close the shutoff so the hose remains full. In about one hour of full sun it will be toasty warm.
Excellent suggestion !
