Frequently Asked Questions

When the tap is opened, the hot water in the unit flows out. The colder water that was sitting upstream of the unit, enters the unit to be heated. If the tap remains open, the newly heated water flows out, being replaced eventually, (depending on the distance to the main water heater), with the water from the main water heater.

If your bathtub is bigger than your main heater tank, this unit isn’t going to do much for you. It will add 2.5, 4, or 7 gallons to the capacity of your main tank, depending on which unit you buy.
