    #Energy savings of up to 78% and 80% are based on operation at Condition #2 & Condition #4 of AS/NZS 5125. Any savings will vary depending upon your location, type of water heater being replaced, hot water consumption and fuel tariff. Before installation – seek advice as to suitability for household usage and tariffs. The impact on an electricity account will depend on the tariff arrangement of the water heater being replaced and where you live. The water heater is recommended for connection to an uninterrupted 24-hour continuous tariff power supply. Depending upon the size of the household and its hot water requirements, and if the Electricity Retailer permits, an extended off-peak (overnight and day) or extended time-controlled power supply connection of a minimum 16 hours per day may also be suitable. Before purchase, consult your energy provider for more information on cost comparisons.
