In a postcode with an average household size of 2.4 and a big share of separate houses, hot water demand is steady, so the savings really add up over time.
Mandalong’s solar exposure is excellent for efficient hot water. The local weather station records an average of about 16 MJ/m² of sunshine a day across the year – roughly 4.4 kWh/m²/day – which is ideal for a solar hot water system or a modern heat pump hot water system that sips electricity while pulling free heat from the air. For many homes, upgrading from older gas or an ageing electric hot water system to a heat pump or solar hot water heating system can trim a big chunk off annual energy use. Over the life of the unit, the annual hot water energy savings can easily reach into the thousands of dollars.
Around 6,276 occupied private dwellings across 2264 means plenty of roofs and yards that can host a solar hot water installation or an all‑electric heat pump hot water installation. Families and downsizers alike are looking for the most efficient hot water system they can reasonably afford. Local installers see strong interest in brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Thermann for both solar hot water tank replacement and new builds, as people search for the best hot water system Australia can offer for long‑term reliability.
Typical annual bill savings in Mandalong look like this:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system with solar: $200–$450 per year
With a growing focus on electrification, many locals are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, to find the right mix of upfront hot water system price, running costs and roof space. Heat pump hot water price can look higher at first glance, but once you factor in rebates and the lower operating cost, the payback can be surprisingly quick. The same goes for solar hot water price when you include the value of free solar energy.
