How do I prevent hard water scale?
X3 Scale Prevention Technology
Unprotected tankless:
Failed at 5.8 simulated years and 136,000 gallons
Tankless with X3 Technology
Still running after 19.7 simulated years and 460,000 gallons
Product Preservers
®
For applications when X3
®
Technology is not available, Takagi Product Preservers anti-scale
filters protect your tankless water heater from damage due to scale formation. This system does
not add chemicals to the water or require electricity. As water flows through the filter, hard
water minerals form inactive scale crystals which flow through the water heater without sticking
to the heat exchanger.
Product Preservers are not needed for units with X3 Technology. Product Preservers filters are a minimal maintenance solution, which
require replacement every two years.

Takagi has combined its expertise in water heating and treatment to create X3
®
Scale Prevention Technology. By preventing
scale from ever forming, this feature extends the life of the unit three times longer than traditional tankless. This makes it the first
tankless product that maintains “like-new” performance without requiring any scale-related maintenance.
Takagi stands behind this revolutionary product with the industry’s first ever “Peace of Mind” limited warranty. Unlike
competitive warranties, this 15-year limited warranty covers scale-related failures should they occur.
