An Energie Ecotop domestic water heating system consists of a 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. The Ecotop model has the compressor and control panel mounted above the cylinder giving it a smaller footprint.
The Ecotop cylinder is stainless steel and comes in 250L or 300L capacity with one solar thermodynamic panel. The compressor uses just 390watts when it runs, and it only runs intermittently. It uses minimal electricity.
The system has 3 modes of operation, Eco, Boost and Auto so can provide reliable hot water for changing requirements. It is most efficient when the panel is in the sun but does not rely on the sun to operate effectively. The 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 whihc is the recommended temperature for d°omestic hot water. Once a week the water heats to 65°C to comply with the anti-legionella requirements.
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.

The Energie Eco system must be installed by a qualified plumber and a qualified refrigerant engineer, who must commission the system. Relevant installation documents can be supplied by The Alternative Energy Company on request. The Alternative Installation company handle the refrigeration side of the install and include it in their pricing. Correct installation is important for effective operation and, once installed correctly, it is maintenance free.
Energie Eco systems, if designed, used, installed and maintained in accordance with the statements and conditions of the technical literature, will meet or contribute to meeting the following provisions of the NZBC:
The products meet the requirements set out in the following documents, or relevant parts of cited standards within the documents (available on request):
The Energie Eco system is manufactured to the highest standards and certified under the following management systems:
The Alternative Energy Company is the New Zealand supplier of solar thermodynamic hot water systems made by Energie (Portugal), and Eurothane GP PIR insulation panels made by Recticel (UK).
