Our coastal climate helps. The nearby Long Reef Golf Club weather station records an average annual solar exposure of about 16.7 MJ/m² per day – roughly 4.6 kWh/m²/day – which is excellent for both a solar hot water heating system and a modern heat pump hot water system.

There are also programs that can act like an electric hot water system rebate when you switch away from gas. These hot water rebate NSW incentives can cut the upfront heat pump hot water price or solar hot water price by a substantial percentage, and many locals see payback periods drop to just a few years – especially if they already have rooftop solar or use timers and solar‑diversion to run their system during the day.

If you are weighing up electric hot water vs gas hot water, or comparing heat pump vs solar hot water for a Dee Why Beach property, it is worth looking beyond just the hot water system price or cost.
