Boiler design

Minimal space requirements X
The MinoWIN2 is a small space-saving miracle. With its small dimensions and light weight of 25 kilograms, it can be integrated anywhere. The MinoWIN2 can be operated both independently and dependently of the surrounding air and can be combined with an inexpensive Windhager plastic flue gas system. This allows a high degree of flexibility in terms of installation and is ideally suited for modernisation projects!
Intelligent combustion technology X
The burner unit and the heat exchanger combined ensure the best energy extraction: Efficiency levels of over 110 per cent, virtually residue-free combustion and high environmental compatibility are your plus points! In addition, the MinoWIN2 is whisper-quiet in operation thanks to the insulation integrated into the cladding.
Compact, durable heat exchanger X
The heat exchanger made of cast aluminium-silicon with a ceramic coating is extremely robust and compact. Thanks to the low water content, the required heat is transferred very quickly. In addition, combustion residues hardly have a chance to get stuck. We are so convinced of the quality of our heat exchanger that we guarantee it for up to ten years.
Built-in heating fittings X
The MinoWIN2 already has all of the necessary hydraulic fittings installed, such as the expansion tank, the energy-saving circulation pump and the valve. This also saves a lot of space.
Energy-saving circulating pump X
The high-efficiency pump included as standard helps you save money every day: It continuously adjusts its output automatically to the actual requirements and always pumps only exactly as much water through the heating system as is currently needed.
Integrated hot water provision X
The MinoWIN2 Combi has an additional stainless steel plate heat exchanger as standard, which produces hot water on the continuous flow principle. Thanks to the automatic boost function, it delivers hot water quickly - and with the same minimal dimensions.

The advantages at a glance
+ Easy to integrate anywhere thanks to the smallest space requirements and high flexibility in mounting
+ Optional combined solution for integrated hot water provision
+ Economical energy consumption due to condensing boiler technology and energy-saving circulating pump

MinoWIN2
Heating and hot water provision in one unit – the MinoWIN2 Combi makes it possible with an integrated plate heat exchanger. With the same dimensions as the MinoWIN2, it is extremely space-saving and the ideal solution for houses or flats without a cellar.
