The young boy played in the warm Sprinkler for over an hour. He was a wrinkled prune when the water was shut off. He did make a dent in the water tank temp. 120 gal. from 61 Deg C down to 36 Deg C. and today the water is back up to 61 Deg. The cost for operation under $0.07 I'm thinking about the time when he becomes a teenager and some teenagers take some long showers. We pump our own water and heat with solar. Shower on.
Killing weeds we use a mixture of salt, vinegar and dishwash soap. I had tryed boiling water for the weeds that grow up the cracks and joints of the concrete but the concrete cools the hot water and defeats the effectiveness.
