Electric Hot Water Adelaide

A twin element hot water heater acts as a boost, to provide additional hot water if required. The bottom element on a twin element hot water heater is generally connected to J Tariff (the cheaper off peak tariff) and the second element generally located toward the top of the tank, is connected to M tariff, acting as a boost (if required) which will heat up a small amount of stored water toward the top of the tank. Storage hot water heaters typically stored water at above 70deg Celsius to prevent legionnaires disease from forming. Tempering valves at the heater (where fitted) ensure that a reduced water temperature is delivered to the home for residential applications to prevent scalding, generally in the temperature range of 40-60deg. Storage hot water heaters can have 5, 7 and 10 year tank warranties pending manufactures and models. As a buyer, you may wish to purchase additional warranties to suit your requirements. The tanks are either made from mild/stainless steel are are coated/lined with various materials. Where the cold water supply to the storage hot water heater has a high content of dissolved minerals such as limestone, heating the water causes the minerals to precipitate in the tank. Storage hot water heaters can develop leaks due to corrosion after only a few years. Dissolved oxygen in the water can also accelerate corrosion of the tank and its fittings.
