iL6 Legionator

The Legionator heats and disinfects water simultaneously.
A set of high-quality quartz tubes heats water to a
comfortable temperature on-demand. As the water is
exiting the unit, ozone (a highly effective disinfectant) is
injected into the water.

This has two effects:
(1) It disinfects the bacteria in water.
(2) The ozone is then carried in the water to the faucets
and helps mitigate the bacteria present in the faucet
valve seats and aerators.
