Domestic hot water and heating with geothermal energy.

With its slightly higher heat output of 8 kW, the SIW 8TES can be used for a living area of up to 180 sqm. It is installed easily indoors and is used for both heating and domestic hot water preparation. With a width of just 60 cm, the 170 l domestic hot water cylinder and all components required for the heating connection are already pre-installed. Matching sets make the perfect additions for connecting components like the buffer tank or passive cooling station with each other.

• Fast installation. Compact design with integrated components such as heating and brine circulating pump, as well as pressure gauge. Removable heat pump module for easy and safe transportation to the installation site.
• Space-saving. Heating and 170 litre domestic hot water cylinder for even the tightest spaces.
• Flexible. Can be expanded at any time to include passive cooling for efficient temperature control on hot days.
• Really quiet. Thanks to the enclosed compressor chamber and free-swinging compressor base plate.
• Future-orientated. Use of load-variable tariffs or self-produced PV-electricity possible: SmartGrid Ready.
• Intelligent. Eligible for funding in existing buildings thanks to high efficiency. Suitable for use in new builds for compliance with the German federal energy efficiency ordinance (EnEV) and Renewable Energy Heat Act (EEWärmeG).
• Economical. Highest efficiency class A++ for heating and top mark A for domestic hot water preparation.
