Hot water systems in Hawthorn East

Across Hawthorn East, more owners and renters are quietly upgrading to a more energy efficient hot water system. With an average household size of around 2.3 people and more than 6,200 occupied dwellings, reliable hot water is non‑negotiable – but so is keeping running costs under control. Power prices keep rising, and many homes are still on older gas or electric hot water that chew through energy. Switching to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step for comfort and savings.

Hawthorn East is actually very well suited to efficient hot water. Local solar exposure averages about 15 MJ/m² per day – roughly 4.2 kWh/m² – which is strong support for both a solar hot water heating system and high‑performance heat pump hot water. With a high proportion of apartments and townhouses as well as separate houses, and solid median household and family incomes, many residents can comfortably invest in upgrades that pay themselves back through lower bills. For many families, hot water is one of the biggest single energy uses at home, so the annual hot water energy savings from moving off old gas or resistive electric units can be substantial.

In 3123, we are seeing a steady shift away from gas towards electric hot water vs gas hot water options that make better use of rooftop solar and off‑peak tariffs. A modern heat pump hot water installation can cut hot water energy use by up to two‑thirds compared with an old electric hot water system, and a well‑designed solar hot water installation can deliver similar or better savings. Brands like Rheem heat pump hot water, Sanden heat pump systems, Rinnai solar hot water and Chromagen solar hot water are all common choices locally for those chasing the most efficient hot water system for their property.

Typical bill savings in Hawthorn East look like this:

• Old electric to heat pump hot water system: about $350–$700 a year • Gas to heat pump hot water: about $250–$600 a year • Gas to solar hot water system: about $200–$550 a year • Old electric to modern electric hot water installation with good rooftop solar: about $250–$500 a year

These are averages only, but they show why many households now compare heat pump vs solar hot water, and even solar hot water vs electric hot water with solar, when planning their next hot water installation.

Recent data shows 162 efficient hot water systems (heat pumps and solar hot water) have already been installed in Hawthorn East. Installations peaked between about 2008 and 2016, when solar hot water price and rebates were especially attractive, and have picked up again in the early 2020s as more people focus on electrification and lower running costs. The trend line in the yearly data – from just one or two systems a year in the early 2000s to regular installations every year since – reflects a clear, growing interest in energy efficient hot water system options and future‑proofing homes in Hawthorn East.
