About us & experience

Two brothers.
One complete picture.

We are two brothers from South Tyrol, now at home in Switzerland. Our careers have led us into two technical fields that complement each other: heating and building technology, and electrical engineering and renewable energy systems.

Two complementary fields of expertise.

We approach energy projects as complete energy systems. Solar PV, battery storage, heat pumps, building technology and intelligent controls are coordinated from the outset.

Patrick Prünster

Heating & building technology

Around 18 years of professional experience

Patrick has around 18 years of professional experience in heating, control and building technology.

His focus is on integrating and coordinating system components – from heat pumps and heating systems to controls, building management systems and intelligent energy control.

Most recently, Patrick worked at Bosch Home Comfort in Munich. His work included technical customer service and complex heating, control and building automation systems.

Today, he applies this knowledge wherever solar PV, battery storage, heat pumps and building technology need to be combined into an efficient overall system.

  • Heat pumps & heating systems
  • Controls & building management
  • Intelligent energy control
