As there are several types of hot water systems used in Australia. The most used are Storage Tank systems, where hot water is stored in a tank and kept at a set temperature. Many households prefer Instantaneous or Continuous Flow systems, as these systems heat water on demand, as it flows through the system, providing hot water as soon as it's needed. Whereas, the one of the highly efficient options is Heat Pump systems as these systems work by absorbing heat from the air or ground and using it to heat water. Then, we have a cost-effective and environmentally friendly option as well in the form of Solar Hot Water systems, which use energy from the sun to heat water. Many households now prefer going for Electric or Gas Boosted Solar systems. These systems use a combination of solar panels and either electric or gas boosters to provide hot water. In the last, but widely used in the regions where the natural gas supply is easily available is Gas Storage Tank systems. These systems use natural gas or propane to heat water, and the hot water is stored in a tank.
To find out the most suitable hot water system will depend on several factors, including the climate, local weather conditions, and the availability of different energy sources in different regions of Australia. It is important to note that some hot water systems may require additional support or boosters to ensure they are able to provide hot water effectively in extreme weather conditions also. As per the region and its climatic conditions, we have seen that Solar hot water systems are most suitable for areas with abundant sunshine, such as Queensland, Northern New South Wales, and Western Australia. For the areas with milder climates, such as Victoria and Tasmania, Heat pump systems are ideal, as they work best in temperatures between 7°C and 43°C. Gas hot water systems are most suitable for areas with access to natural gas or propane, and are often used in urban and suburban areas. Electric hot water systems are a good option for areas without access to natural gas or propane, or for those who prefer an all-electric home. This have been a generalized understanding, but the comfort level, household size and their hot water requirement are also to be understood.
