Hot water systems in Whittingham
Across Whittingham and the wider 2330 area, more households are rethinking their old gas and electric hot water system and switching to energy efficient options. With an average household size of around 2.6 people and more than 7,600 occupied dwellings in the postcode, reliable, affordable hot water is a big part of everyday life. Power prices keep creeping up, so moving to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step for many families.
Whittingham’s climate is ideal for efficient hot water. Nearby Singleton records strong sunshine, with mean daily solar exposure of about 17.1 MJ/m², or roughly 4.75 kWh/m² per day over the year. That level of solar energy supports both heat pump hot water and a solar hot water heating system, especially for homes that already have rooftop solar. For owner occupiers – over 5,300 households across the postcode either own outright or with a mortgage – upgrading to the most efficient hot water system can deliver solid annual energy savings and help ease those typical mortgage repayments of around $1,820 a month.
In the 2330 area, most homes are separate houses with three or four bedrooms, so hot water demand is steady, particularly for families with kids. That makes the choice between heat pump vs solar hot water important. A quality heat pump hot water installation will generally use a fraction of the electricity of an old electric storage unit, while a well-sized solar hot water installation can use the sun to do most of the work. Brands like Rheem heat pump hot water, Sanden heat pump systems and Rheem solar hot water are popular options for those chasing low running costs, while Rinnai solar hot water and Chromagen solar hot water units are common on roofs around the Hunter.
When you look at the numbers, the savings are compelling. A modern energy efficient hot water system can slash the share of your household energy going into water heating. Typical annual bill savings in Whittingham might look like:
• Old electric to heat pump hot water system: save about $350–$700 per year • Gas to heat pump hot water system: save about $250–$600 per year • Gas to solar hot water system: save about $200–$550 per year • Old electric to modern electric hot water installation with good solar: save about $200–$450 per year
Over time, these savings add up across the community, especially as more homes add solar and efficient hot water.
Efficient hot water is not new to Whittingham. There have already been 1,261 efficient hot water installations (heat pumps and solar hot water) recorded in the 2330 postcode. Installations climbed steadily through the 2000s, peaking around 2009–2011 when more than 580 systems went in over just three years. While annual numbers have eased since then, with 2023 and 2024 still adding dozens of new systems, the trend shows ongoing local interest in electrification, lower running costs and moving away from gas hot water where it makes sense.
