All Rezi Water Heaters add approx 25 degrees celcius to the ambient water temperature. The ambient temperature will vary depending upon your location and season.

eg: If your Ambient water temperature is 15 degrees celcius (water flowing in to the heater), the result is an output of 40 degrees celcius. 

The volume of hot water achieved is dependant upon the Rezi Water Heater model you choose. 

The Rezi model you choose depends upon the amperage available.

A win-win for the Environment and You!

When you use the Rezi water heater, electricity is only consumed during water consumption, thus making running costs much cheaper than other water heaters.   Why?  Because the unit is small and may be installed safely at any angle and very close to the outlet, unlike a gas heater or conventional storage heater.
