System Design

Energen systems are designed around the daily load, differential temperature required, peak load, time between peaks, area available for collectors, storage tanks, heat pumps and other typical site conditions and requirements.

Energens solar hybrid system is a combination of twin coiled enamelled storage tanks (suitable storage device), high efficiency EHS P collectors, high efficiency heat pumps, closed circuit circulation systems, solar and heat pump controllers.

Why Energen?

Advantages

New Generation Closed Circuit System:
The system design is a new generation fully closed circuit system. The collectors and the heat pumps are not exposed to the vagaries of the potable water conditions because no water flows through the collectors or the heat exchanger in a heat pump. The collectors and the bottom coil in the tank form a closed circuit on one side, the heat pump and the top coil forms a closed circuit on the other side. Only closed circuit liquid flows through the collectors and the heat pump. There is no scaling, reduction in performance, requirement of regular de-scaling or regular downtime for repair. This not only ensures long life but also a reliable hot water supply with peak performance year on year.

Energen Product Features and Benefits
