Condensing Gas - Solar
Water Heater

SGE - 40/60

Fully room-sealed condensing high efficiency gas-solar water heater

with integrated solar heat exchanger (95 % gross) • Maximum solar

contribution through fully integrated intelligent solar controller

• 1 control and display unit for the complete installation • Very small
footprint because of integrated solar heat exchanger • Flexible ue
options (maximum length 100 meters) • Thermocontrol for easy
exible control / fault diagnosis • Programmable for legionella
purge cycle • All models suitable for natural or LP gas • Scale

formation is reduced through the improved design and location

of the heat exchanger • Very easy maintenance and installation

• Remote control connection • Voltage-free contact for general

fault indication

Innovation has a name.
