Long Island’s climate is ideal for an energy efficient hot water system. The local solar exposure averages about 20 MJ/m² a day – roughly 5.5 kWh/m² – which is excellent for both a solar hot water heating system and high‑efficiency heat pump hot water. That sunshine, combined with the region’s push towards electrification, makes upgrading from older gas or resistive electric hot water to a modern heat pump hot water system or quality solar hot water system a logical next step. Over the life of the unit, Annual Hot Water Energy Savings can easily reach hundreds of dollars per year, especially when paired with rooftop solar.
Across postcode 4741 there are 2,324 occupied private dwellings, mostly separate houses with three or four bedrooms, so hot water demand is steady and predictable. Many households are still on gas or older electric units, even though hot water energy use can be one of the biggest chunks of the power bill. That is why the most efficient hot water system options – like a Sanden heat pump or Rheem heat pump hot water – are gaining ground, along with popular brands such as Rheem solar hot water and Rinnai solar hot water. For those wanting a robust solar hot water heating system, Chromagen solar hot water is also a familiar name in the Australian market and suits coastal conditions well.
Typical hot water installation choices on Long Island include solar hot water installation with a roof‑mounted solar hot water tank replacement, heat pump hot water installation beside the house, or electric hot water installation designed to soak up excess rooftop solar. When comparing heat pump vs solar hot water, the best option often comes down to roof space, budget, and whether you want to go fully all‑electric. Many locals are also weighing up solar hot water vs electric hot water, and electric hot water vs gas hot water, to find the best hot water system Australia can offer for their situation.
Average annual bill savings for common upgrade paths on Long Island QLD can look like this:
• Old electric to heat pump hot water system: $350–$700 per year • Gas storage to heat pump hot water: $250–$600 per year • Gas storage to solar hot water system: $300–$650 per year • Old electric to modern electric hot water system with solar: $200–$500 per year
