Cerapur Aero from Junkers combines the benefits of condensing technology and heat pump technology in a compact device. This wall-hung hybrid unit with intelligent controller consists of an air/water heat pump and an efficient gas condensing boiler. Cerapur Aero enables heating installers to offer their customers an interesting solution using a renewable energy source. The device is particularly useful for the modernisation of single-family homes where the heating is located in the cellar or under the roof.
With dimensions of 890 x 600 x 480 mm (height x width x depth), the system is among the smallest condensing heat pump combinations in the market. There is no need for complex and expensive planning. Installation is easy too, because all components come pre-installed and pre-configured. Plus, no time-consuming construction work is required. The air/water heat pump recovers the energy from the outside air through an air channel system that is easy to install.
The output of the heat pump is about 2 kilowatts and it achieves a COP of 3.5 (to EN 14511 with A7/W35). The gas condensing unit draws on the long-standing experience with the Cerapur boilers built by Junkers, the thermotechnology specialist. Two versions are available with outputs of 14 and 24 kilowatts. The modules making up this hybrid system are perfectly matched by the manufacturer. The intelligent “Opti Energy” controller offers the consumer a choice between optimised costs and optimised CO2 emissions. Once the costs of gas and power have been entered via the user interface, “Opti Energy” sets the switch-off point of the heat pump in such a way that the cheaper energy source is used at all times in the cost-optimised mode. Compared to a stand-alone gas condensing solution, this allows for a further considerable reduction in energy consumption and costs
