Thanks for the heads up on the bacteria in the hot water tank etc... I now have a heat pump hot water heater that uses the heat in the air to maintain the temp at 120F all the time...it uses less energy than the hot water timer on an electric tank and keeps the water the same temp all day... Uses 2 KWH per day for 50 gallon tank... I have a video of it but won't post it here..
