Patrick Prünster is Managing Director of PHT Energietechnik GmbH in Pfäffikon SZ. His work covers solar PV, battery storage, heat pumps, control engineering, load management and technically sound use of solar surplus.
In South Tyrol he completed vocational training as a chimney sweep, earning a journeyman’s certificate. He then completed training as an electrician, also with a journeyman’s certificate. His subsequent work as a heating and control systems technician shaped his understanding of how electricity, heat and controls work together.
He gained further experience at Bosch Home Comfort in Munich in modern heating and energy systems. Today he brings these disciplines together in Switzerland to create solutions that are understandable, expandable and carefully delivered.
His design principle is to understand the building, demand and objective first; then size components, clarify interfaces and optimise operation using real data.
