The dual system Pellet Boiler OCTO PLUS – Austrian manufacturer SOLARFOCUS’ latest innovation – fully integrates the Buffer and Solar Thermal energy supply within one unit, a very compact combination resulting in the minimum of Pellet consumption. The new Boiler combines a compact downdraught combustion Pellet Boiler unit with a clever Buffer solution and latest Solar engineering into one compact unit. When the energy required for heating and domestic hot water preparation cannot be supplied by the sun, the integrated Pellet Boiler tops up the necessary energy. This integrated concept of Solar heat and Pellet technology achieves a complete system efficiency of 94% for Pellets due to the direct delivery of heat from the Boiler’s heat exchangers, into the centre of the Buffer Tank. Due to the compact design, the Pellet Boiler OCTO PLUS requires just under 1 M² of floor space. Installation of the OCTO PLUS is easy and straightforward as it is composed of compact modules. The Touchscreen display allows for easy, intuitive and complete Building Heat Management, including Solar Thermal, integrating everything into one central control. The attractive design completes the advantages of compactness, energy savings, innovative function and easy handling of the OCTO PLUS. The OCTO PLUS is available in two sizes: 2.9-10 kW or 2.9-15 kW, with a 500 L Buffer Tank with standard stratification of the heating return and Solar Heat Exchanger.
