Introduction
About the water heater
The SCC water heater is intended for heating water for sanitary purposes.
The SCC is a condensing gas–fired storage water heater with a fan in the air intake. The
flue gasses transfer their heat to the water through an efficient heat exchanger. The water
heater has a concentric venting connector and can function as an open or as a room-
sealed water heater.
Working principle
Cold water enters the bottom of the tank through the water inlet (1). A heat exchanger (2)
transfers the heat from the flue gasses to the water and the hot water leaves the tank
through the water outlet (3) at the top of the tank. The tank of the water heater has to be
completely filled during operation. The tank at least must remain under mains water
supply pressure at any time. Fresh cold water is immediately added when hot water is
drawn from the water heater. A temperature sensor measures the water temperature.
