Innovative and top-class hybrid technology with a heat pump, solar buffer tank and gas-condensing boiler in one compact high-tech system.

The premium components:

• Unpressurised 500-litre buffer storage tank, fitted as standard with spiral heat exchanger for solar connection and spiral pipe for heating drinking water by means of the particularly hygienic continuous flow system
• Air/water heat pump (7.3 kW, COP 4.1) – largely identical with the tried and tested ThermiStar L version; also available with cooling module
• Premium gas-condensing boiler (7.7 to 26.8 kW)
• Intelligent system control from Siemens
• Includes as standard a solar connection to supply drinking water and supplement your heating system
• Independence from fossil fuels as a large proportion of the heating and warm-water requirements, especially in old buildings, are met by renewable energy sources
• Maximum energy savings and environmentally friendly thanks to the large proportion of renewable energy
• Costs less and takes up less space than complex systems
• Ready-to-install unit with time-saving and cost-saving installation
• Very easy to install thanks to compact design and wheels fitted to the back of the boiler
• Clear, straightforward design and optimum accessibility of all the components make for ease of assembly and maintenance 
• Can be fitted even where there is no piped gas - in regions without a piped gas supply, liquid gas can always be used
  
• Large state subsidies
