The Legionator is unlike any point-of-use system on the market. Intellihot has designed and engineered a unit that not only heats water but also disinfects using Ozone Gas.
A set of high-quality quartz tubes heats water to a comfortable temperature as soon as the water starts flowing. As the water is exiting the unit, ozone gas is injected into the water. This has two effects – (1) it mitigates the bacteria in the water (2) This ozone is also carried in the water to the faucets and mitigates the bacteria present within the faucet valve seats and aerators. End result – you get good, clean, safe, and efficiently heated water ensuring your building and its occupants are protected from water-borne bacteria illnesses.
