Why Descale Regularly?
Mineral deposits accumulate over time inside tankless water heater heat exchangers, particularly in areas with hard water. This buildup acts as an insulating barrier, forcing the unit to work harder and consume more energy to deliver the same hot water output. Periodic descaling with the Nu-Calgon 4387-01 kit helps prevent costly repairs, reduces energy consumption, and keeps the system running at peak performance.
