You can see it in Bernhard Spielvogel’s face – the joy of having successfully transformed a standard kitchen stove into a micro-CHP unit. Indeed, our Gen70DR Stirling generator shows what it is capable of. Simply place the unit with the disc-shaped heat exchanger in the opening of the hotplate and stoke it up. After a short warm-up time, the generator midget starts automatically and increases its power continuously up to 1000 watts and more. Heating, cooking and generating sufficient electricity from the kitchen stove is no longer utopian and can open up new applications in remote mountain huts and buildings without electricity. Further application options include the coverage of blackout scenarios.

The continuous running capability is the key

At first glance, a generator output of one kilowatt may seem insufficient to supply a building or an apartment. In fact, the unit delivers 24 kWh per day in continuous operation. According to statistics, a three-person household needs about 10 kWh per day, provided that no heat pump is operated. However, peak power of up to 10 kW often has to be covered briefly. Our generator system therefore uses a short-term storage unit that takes over the peak loads and, in conjunction with a standard inverter, provides a stable grid supply. The use of existing PV storage batteries is another option for a high-quality stand-alone supply. We are happy to demonstrate this on our test stands.

Back to the kitchen stove: Because such an arrangement requires constant manual refilling of fuel, pellet firing systems with automated loading are particularly suitable for continuous operation. We would like to take this opportunity to draw your attention to our presentation at the European Pellets Conference in Wels on March 5, 2025. Download presentation Dipl. Ing.

Safety note:

The use of our Stirling generators with commercially available devices for heat generation is part of our research and development to gain new insights.
Please note that a comparable application outside our sphere of influence would constitute a change in the intended use of an authorised combustion device. We therefore ask for your understanding that we can only respond to enquiries from relevant companies that have a corresponding licence and experience in handling furnaces. Private individuals should therefore contact their heating or boiler manufacturer.
