Energie Eco Solar Thermodynamic Domestic Water Heating — Small to Medium

An Energie Eco domestic water heating system for small to medium-sized homes consists of an Eco cylinder, with its attached compressor and heat exchanger, and an 8kg aluminium thermodynamic panel, which is externally mounted on the roof, wall, balcony or ground.

Energie thermodynamic solar hot water system produces hot water 24 hours a day, 365 days a year. Energie Eco works in all weather conditions, and even at night. No separate back-up system is required.

Water in the cylinder is heated to 55°C. The average power consumption is 390W.

How Eco Works

A refrigerant liquid (R134A) passes through the thermodynamic panel gathering heat from solar radiation, environmental temperature, rain, wind and snow. This causes the refrigerant to become a hot gas which is then compressed, further increasing its temperature.

The heat is then transferred to the water via a heat exchanger coil which is wrapped around the outside of the cylinder. The gas is decompressed and condenses back into a liquid which returns to the panel, and the process repeats.
