Iron Gates and the wider 2473 area enjoy strong sunshine, with mean daily solar exposure of about 18.4 MJ/m², or roughly 5.1 kWh/m² per day. That level of sun is ideal for a solar hot water system or heat pump hot water system, especially if you already have rooftop solar or are planning to go all‑electric.

Across the postcode there are 1,390 occupied private dwellings, mostly separate houses with two or three bedrooms. That lines up well with popular system sizes like 250–315 litre heat pump hot water installation or a roof‑mounted solar hot water heating system with a 250–300 litre tank. Hot water typically makes up 20–30% of home electricity use, so upgrading from an old electric hot water system or gas storage unit can unlock meaningful savings.
Typical annual bill savings in Iron Gates can look like this:
• Old electric to heat pump: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water: $250–$550 per year • Old electric to modern electric with solar: $200–$450 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are common choices for reliable, mainstream systems, while Rinnai solar hot water and Chromagen solar hot water options suit homes wanting strong performance from a solar hot water installation. For those chasing the most efficient hot water system, premium units such as a Sanden heat pump are often considered among the best heat pump hot water system options in Australia, especially when paired with rooftop solar.
Efficient hot water is not new to Iron Gates. There have already been 410 efficient hot water systems installed in the 2473 postcode, combining heat pump and solar hot water installations. Uptake really took off around 2009 and 2011, with 70 and 47 installations respectively, and there has been a steady trickle of systems going in each year since, including recent growth through 2024 and 2025. This trend shows more households are looking at heat pump vs solar hot water, comparing solar hot water vs electric hot water, and choosing systems that lower running costs and support electrification.
When it comes to hot water repair and hot water tank replacement, many locals now use the opportunity to move from gas to an energy efficient hot water system. A solar hot water tank replacement, for example, can be a chance to upgrade to the latest rheem solar hot water or rinnai solar hot water tank, or even switch to a sanden heat pump if you want whisper‑quiet, ultra‑efficient performance. Modern electric hot water installation can also make sense when paired with rooftop solar and smart timers, especially if you are comparing electric hot water vs gas hot water and want to simplify to an all‑electric home.
Hot Water Rebates, Tariffs & Savings
For hot water NSW homes, rebates and incentives can make a big difference to the hot water system price.
