water constantly gallon great heater constant buy regular power limited -
This was a great idea for the whole house. It only uses power when your using it so you save by not constantly hearing that 60 gallon water heater throughout the day. Most importantly you get constant hot water, it's not limited to the gallon limitations on a regular tank water heater!! Great buy!
