Hot water systems in Hawthorn West
In Hawthorn West, more households and businesses are rethinking how they heat their water. With energy prices climbing and a strong local focus on sustainability, upgrading your hot water system is becoming the logical next step after installing solar or switching away from gas. In a postcode with around 9,700 occupied dwellings and an average household size of 2.1 people, hot water is a big chunk of energy use – so even modest efficiency gains add up to serious annual hot water energy savings.
Hawthorn’s climate is ideal for efficient hot water. The local weather station at Scotch College records an average annual solar exposure of about 15 MJ/m² per day, which is roughly 4.2 kWh/m² per day. That level of sunshine supports both a modern heat pump hot water system and a solar hot water system, helping them run efficiently year-round. With a mix of established homes (over 2,600 owned outright) and a large rental market (more than 4,400 rented dwellings), there is strong potential for energy efficient hot water system upgrades in everything from family homes to boutique offices and apartments.
Across 3122, there have already been 202 efficient hot water installations – mainly heat pump hot water installation and solar hot water installation – showing steady interest in electrification and lower running costs. Installations peaked around 2008–2010 and have continued at a consistent level through to 2024, as more locals look at heat pump vs solar hot water when their old gas or electric units fail. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are increasingly common on local jobs, alongside options such as Chromagen solar hot water for both homes and light commercial sites.
For a typical Hawthorn West household, hot water can easily be 20–30% of total energy use. That is why upgrading from an old gas or electric hot water system makes sense. A quality heat pump hot water system is often considered one of the best heat pump hot water system choices in Australia, especially when paired with rooftop solar. A well-designed solar hot water heating system or rheem solar hot water setup can also slash bills, while a modern electric hot water system with smart controls can work brilliantly in all-electric homes.
Here are realistic average annual bill savings many Hawthorn West households see when they upgrade:
• Old electric to heat pump hot water system: $450–$900 per year • Gas hot water to heat pump: $350–$750 per year • Gas hot water to solar hot water system: $300–$700 per year • Old electric to new electric hot water system run mostly on solar: $300–$650 per year
Of course, every hot water installation is different, and hot water system price / cost will vary based on brand, size and complexity. Heat pump hot water price / cost can look higher upfront than a basic electric hot water installation, but running costs are usually much lower. Likewise, solar hot water price / cost depends on collectors, tank size and whether you need a solar hot water tank replacement or a full new system. Many locals see a heat pump or solar hot water vs electric hot water running on grid power as a clear long-term win.
When it comes to hot water repair and replacement, Hawthorn West homeowners often weigh up whether to stick with gas, choose an efficient electric hot water system, or move to a solar hot water system. Popular brands like Sanden heat pump and Rheem heat pump hot water are known for high efficiency, while Rinnai solar hot water and Chromagen solar hot water offer proven solar hot water repair and replacement options. Comparing electric hot water vs gas hot water, the trend here is moving towards all-electric, especially in apartments and townhouses where flues and gas connections can be expensive to maintain.
