Heating system
The Direct Coil
™
heating system is enclosed within a pressure-test-
ed plastic jacket. The heating system with its nichrome heating
element is suitable for hard and soft water areas and is largely
insusceptible to scale build-up. The Direct Coil
™
heating system
ensures rapid, accurate, and efficient DHW production.
Note
The water heater is equipped with an air detector that
largely prevents damage to the heating system. If, during
operation, air is drawn into the water heater, the water
heater shuts down the heating output for one minute to
protect the heating system.
