Water heater protection
HALO Heater Guardian Elite
The HALO Heater Guardian Elite protects the single most expensive plumbing appliance in the house. It sits on the cold feed to the water heater and does two things: filters out the sediment and rust that settle in a tank and clog a tankless heat exchanger, and inhibits the scale that shortens element and burner life.
Filter, then scale inhibitor
Incoming water first passes through a proprietary two-chamber filter that captures silt, dirt, rust and sediment. It then flows through a scale-inhibitor chamber that keeps dissolved hardness from crystallising onto the heat exchanger, elements or burner.
A reversible bracket lets it mount in either orientation for a tight spot, a liquid-filled pressure gauge shows when the filter is loading up, and a pressure-relief feature makes the filter change quick. It needs no electricity.

Tank or tankless
On a tank heater it slows sediment build-up on the bottom and scale on the element, so the tank holds capacity and lasts longer. On a tankless unit — which is far more sensitive to scale — it reduces how often the heat exchanger needs descaling. It is not a substitute for whole-home treatment, but it is inexpensive insurance for the heater.
- Protects a tank or tankless water heater
- Sediment and rust filtration plus scale control

How Milani installs and looks after it
Milani installs HALO equipment on the main line where water enters the home (or, for drinking-water and point-of-use units, under the kitchen sink), tests your water first so the system is matched to what you actually have, and sets it up with the correct bypass and shut-offs so future service is simple. Where a unit has replaceable cartridges or media, we tell you the schedule and supply the parts.

Warranty
The HALO Heater Guardian Elite carries HALO's limited warranty on the housing; the filter is a maintenance item. Milani registers the unit and supplies replacement filters.
