SOLID. STATE.
WHAT IS HARD WATER SCALE:
• More than 85% of American homes
have hard water with high mineral
content (generally magnesium and
calcium)
• These minerals can precipitate out
of the water leaving behind a solid
mineral deposit called hard water
scale.
• Scale acts as a thermal insulator
preventing full transfer of heat from
the burner into the water reducing the
efficiency of the water heater.
• Hard water scale can lead to
overheating and eventually damage to
the water heater components.
HOW IT WORKS:
• As water flows through the filter,
minerals form into inactive scale
crystals.
• This inactive form of scale flows
through the tankless water heater
without sticking to any components.
• This system can even reduce
scale formation on other hot water
appliances and fixtures.
BENEFITS:
• Provides active protection against
scale formation so there is no
requirement to flush/descale the
tankless water heater.
• Does not add chemicals to the water or
require electricity.
• Virtually maintenance free; one simple
filter change every two years to ensure
continuous protection from the effects
of hard water scale.
