Point of Use Advantage

Point of use heated water means that there are no heated tanks with standby water. The Mini-4 simply heats water as it passes through a series of pipes and tubes, instead of drawing it from a heated tank. Basically, it heats water whenever it is needed.


The Mini-4 tankless electric water heater does not use gas to power itself up. This makes it more eco-friendly than gas-powered water heater tanks because gas is non-renewable and electricity can be powered by renewable sources such as the sun, wind, or water.


Tankless heaters are recommended source for areas such as a kitchen or bathroom sink, laundry areas, boats, RVs, and other compact living spaces that may require point of use water heating. Imagine how much you can save with an electric heater for your summer cabin versus a tank heater!

0.5 GPM Flow Reducer

This handy feature is an aerator that fits most faucets, so that no drains or circulating pumps are needed. It allows you to enjoy hot water without “cold spots”. The Mini-4 can save you hundreds on installation costs with this feature!
