Hot water systems in St Kilda South

In St Kilda South, more locals are rethinking their old gas and electric hot water systems and switching to energy efficient options like a modern electric hot water system, a heat pump hot water system or a solar hot water system. With many residents living in apartments and townhouses, and an average household size of just 1.7 people, it makes sense to choose the most efficient hot water system you can so you are not wasting energy heating water you do not use.

The local climate helps. Around Prahran, the mean daily solar exposure averages about 15.1 MJ/m², which is roughly 4.2 kWh of sunshine per square metre per day over the year.

With almost 11,800 occupied dwellings and a strong mix of renters and owners (around 2,700 homes with a mortgage and 1,800 owned outright), upgrading hot water is one of the easiest ways to cut running costs and emissions. Moving from older gas or resistive electric units to an energy efficient hot water system can deliver substantial annual hot water energy savings for St Kilda South households.
