Hot water systems in Harolds Cross
Across Harolds Cross and the wider 2622 area, more households are re‑thinking their hot water system. With power prices rising and many locals already interested in solar and efficiency, upgrading from an old gas or electric hot water system to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Harolds Cross is made up mostly of separate houses, with around 1,547 standalone homes and an average household size of 2.2 people. That means steady hot water demand for showers, washing and everyday living. With many homes owned outright (around 808) or with a mortgage (about 511), plenty of owner‑occupiers are in a good position to invest in an energy efficient hot water system that cuts running costs and future‑proofs the property.
The local climate also helps. The nearby Tallaganda (Tintinara) weather station records an average annual solar exposure of about 16.1 MJ/m² per day, or roughly 4.5 kWh/m²/day. That is solid sunshine for both a solar hot water heating system and a high‑quality heat pump hot water system, especially when paired with rooftop solar. For many Harolds Cross homes, hot water can be one of the biggest energy users, so shifting that load to a heat pump or solar hot water system can deliver meaningful annual hot water energy savings.
In Harolds Cross 2622, efficient hot water upgrades are already underway. There have been 123 efficient hot water installations (heat pump and solar hot water installation combined) recorded in the postcode. Installations climbed strongly around 2009–2011, with a peak of 21 systems in 2011, and there has been a steady trickle of new systems since, including fresh installs in 2024. This pattern shows growing local interest in electrification, lower running costs and moving away from older gas hot water where possible.
For a typical 2–3 person home, a modern heat pump hot water installation or solar hot water installation can cover most, if not all, of your hot water needs. Many Harolds Cross households are comparing heat pump vs solar hot water to see which suits their roof space, budget and lifestyle. Others are looking at solar hot water vs electric hot water, especially if they already have a decent solar array and can run an electric hot water installation on daytime solar.
When you are weighing up the best hot water system Australia can offer for your place, it pays to look at trusted brands that perform well in our climate. Rheem solar hot water and Rinnai solar hot water are popular choices for a solar hot water heating system, while Rheem heat pump hot water and Sanden heat pump units are common options for those chasing the most efficient hot water system with very low running costs. These brands are well supported across NSW, making hot water repair, solar hot water repair and solar hot water tank replacement straightforward when needed.
Typical hot water system price or cost will depend on size, brand and whether you need a straight swap or a more complex hot water installation. As a rough guide, many households upgrading in NSW see average annual bill savings along the following lines:
• Old electric to heat pump hot water system: around $400–$800 per year • Gas to heat pump hot water system: around $300–$600 per year • Gas to solar hot water system: around $250–$500 per year • Old electric to modern electric hot water system run on solar: around $300–$700 per year
On top of bill savings, Harolds Cross homeowners can usually tap into a mix of federal and state incentives. Federal Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. NSW programs can also provide a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate for efficient models. When combined, these hot water rebate NSW options can trim the heat pump hot water price or cost and solar hot water price or cost by a substantial percentage, and shorten payback periods to just a few years. Using timers, smart controls or solar‑diversion can push savings even further by heating water when your solar is producing.
