An Energie Eco domestic water heating system consists of an Eco cylinder, with its attached compressor and heat exchanger, and one or two 8kg aluminium thermodynamic panels, which are externally mounted on the roof, wall, balcony or ground. The cylinder is availabel in 250L, 300L or 500L capacity. The onel panel system compressor uses just 390watts when it runs (and only need to run intermittently) so uses minimal electricity and produces no carbon emissions. The 2 panel comprssor uses 600watts.
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.
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.
Product: | Cylinder: | Panels: |
ECO 250is | 250 litre stainless steel | 1 or 2 |

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 Energy Compnay handle the refrigeration side of the install and include it in their pricing. This is because correct installation is important for effective operation. Once installed correctly it is a maintenance free system.
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).
