You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure. The Solahart warranty (set out above) is in addition to any rights and remedies that you may have under the Australian Consumer Law.
The Solahart PowerStore also has the ability to tell the external control device the amount of hot water available at any time, enabling it to be used as a key component in a sophisticated home energy management system (HEMS) provided by a third party service provider.

HOW YOUR WATER HEATER WORKS The Solahart PowerStore has inbuilt protection against running low on hot water and will also maintain a fixed minimum water temperature as a safety and compliance requirement. During periods when there is no excess power from solar PV generation and heating of the water is required, electricity from the utility grid will be used to ensure the availability of hot water.

This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between a Solahart 315PVV water heater and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding.
Page 25
INSTALLATION CIRCULATED HOT WATER FLOW AND RETURN SYSTEM This water heater should not be installed as part of a circulated hot water flow and return system in a building. The benefits of solar gain will be significantly reduced. If a circulated flow and return system is required, it is necessary to install a secondary water heater supplied from this water heater.
