SIK 6TES

Compact brine-to-water heat pump for indoor installation. 6 kW heat output.

Compact cooling and heating with geothermal heat.

The SIK 6TES is the smallest compact brine-to-water heat pump with 6 kW heat output for heating and optional cooling. Installed indoors, it is ideal for newly built single family homes with a heated living area of up to 140 sqm. Installation is quick and easy thanks to the integrated components required for the heating connection and integration of the heat source: It can also be equipped with a passive cooling station for efficient cooling via geothermal probes in summer. Matching sets make the perfect additions for connecting components like the buffer tank, domestic hot water cylinder and passive cooling station with each other.

  • Fast installation. Compact design with integrated components such as heating and brine circulating pump, expansion vessels and safety valve, as well as pressure gauge.
  • Naturally quiet. Max. 42 dB (A) sound power level. Sound-optimised through insulated metal casing and double vibration-isolated compressor.
  • Expansion options. Modular expansion to include domestic hot water preparation, built-under buffer tank and passive cooling. Even more efficient room temperature control Smart-RTC+.
  • 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).
  • Adjustable. Including for special applications, such as use with a heat source temperature up to –10 °C.
