FTG SM

Pressurised electric water heaters

Compact heater design with two independent hydraulically connected tanks allows an optimum ratio between the space used up and capacity. It is fitted with an electronic control unit featuring the 7 LED display unit that maintains a logical display and control mode regardless of the mounting method – vertically or horizontally on the wall. Water connections are made according to the DIN standards for easy connection to the water mains.
