1 Introduction
The BTL water heater stores and heats water for
sanitary purposes.
Cold water enters the tank (3) through the water
inlet (2). The heated water leaves the tank at the
top through the hot water outlet (1). When hot
water is used, the tank of the water heater is
filled with the same amount of cold water.
To operate the water heater, the control knobs on
the gas control valve (5) are used.
