Novel hot water supply???
Just purchased a small home in North Central Florida….approx 800 sq ft.
It has an old electric water heater. What if I replaced it with the following. Take the current 220v 30 amp line supplying it and split to two 15 amp 110v lines. Install an 8 gal small tank 110v water heater and on the outlet side install a 110 volt point of use heater. Both draw 1440 watts. My thinking is that most of the time the 8 gal would be sufficient but the thermostat on the point of use would be set such that when the water from the 8 gal tank dropped below a certain temp it would kick on. It would be adding heat to water coming from the 8 gal tank which would be warmer than water coming into the house. Keeping 8 gallons warm around the clock sounds to me to be much more economical than keeping 30 or 40 gallons warm around the clock. The cost of these two small heaters is a little less than one standard water heater. Thanks and sorry for the long question
