Hot water systems in Holbrook
Across Holbrook, more locals are rethinking their old gas and electric hot water systems and switching to energy-efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With most of the 953 dwellings in the 2644 postcode being separate houses and an average household size of 2.3 people, hot showers, dishwashers and laundries all add up – so cutting hot water energy use makes a real difference to bills.
Holbrook’s strong sunshine is a big advantage. The local weather station records an average of 17.4 MJ/m² of solar exposure a day – roughly 4.8 kWh/m² – which is ideal for a solar hot water heating system or a high-efficiency heat pump. For many owner-occupiers (over 700 homes are owned outright or with a mortgage), upgrading from an older gas unit to an energy efficient hot water system is a logical next step, with annual hot water energy savings often reaching hundreds of dollars per year.
In 2644, families and older couples make up a large share of the 2,148 residents, which means steady demand for reliable, affordable hot water. A typical three‑bedroom home might use a 250–315 litre hot water system, and hot water can easily be one of the biggest single energy loads. That is why more households are looking at heat pump vs solar hot water, and even solar hot water vs electric hot water, to find the most efficient hot water system for their needs. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and EvoHeat are all common choices when people compare the best hot water system Australia wide.
To give you a feel for the savings, here are typical average annual bill reductions in a town like Holbrook:
• Old electric to heat pump hot water system: $450–$900 per year • Gas to heat pump hot water system: $300–$700 per year • Gas to solar hot water system: $300–$650 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$600 per year
Efficient systems do come with a higher hot water system price upfront, but rebates and running-cost savings help. A quality heat pump hot water price can look steep on paper, yet over its life it often beats a basic electric hot water system cost, especially when paired with solar. Likewise, a solar hot water price or solar hot water tank replacement can be offset by using your existing PV and smart timers to heat water when the sun is out.

That long‑term trend shows growing local interest in electrification, lower running costs and dependable hot water NSW households can rely on.
Hot Water Rebates, Tariffs & Savings
