The following case studies show how Greenflow systems are used in practice – from small apartments to commercial and industrial applications.
The 500 m² bowling alley, previously heated with two 66 kW gas boilers, was fully modernized – and the result is impressive.
We replaced the old total output of 132 kW gas with just:
That means:
132 kW of gas replaced by just 28 kW of Greenflow technology – with the same heating output. Simply more modern, more efficient, and extremely cost-effective.
Isn't that incredible? More comfort, less energy consumption, away from fossil fuels – all with cutting-edge, aerospace-inspired technology.
Greenflow shows how heating can work today.
The owner of an apartment up to 70 square meters was looking for an energy-efficient, space-saving, and reliable heating system.
Challenge: Heating was previously based on a conventional gas boiler, which involved high maintenance effort and high costs.
Solution: The Greenflow Typ 4 system with a rated output of 4 kW is ideal for heating smaller apartments. The maximum current draw is 14 A at a stable voltage of 230/400 V.
Result: Significant energy savings, precise temperature control, and minimal maintenance – since the system has no moving parts.
An efficient, reliable, and cost-effective heating solution for areas of 150–180 m² with minimal maintenance.
Challenge: An area of 150–180 square meters needs to be heated efficiently. The previous system involved high energy consumption.
Solution: The Greenflow Typ 12 operates with a rated output of 12 kW at 400 V. Despite its compact size (34×6×10 cm), it can effectively heat large areas. With copper connections for long-term reliability.
Result: Significantly increased efficiency, stable operation, and comfortable heating of larger areas.
