Hot water systems in Main Arm
In Main Arm, more households are rethinking their old gas and electric hot water system and switching to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With an average household size of around 2.5 people and more than 2,400 occupied dwellings across the 2482 postcode, reliable, affordable hot water is a big deal for local families and shared homes.

Main Arm’s climate is perfect for efficient hot water. The Mullumbimby weather station records mean daily solar exposure of about 17.7 MJ/m², which works out to roughly 4.9 kWh of solar energy per square metre per day. That strong sunlight helps a solar hot water heating system perform well year‑round, and gives a heat pump hot water system plenty of free renewable energy to draw from the air. With many homes owned outright or with a mortgage, and a solid number of families and over‑65s in the area, there is clear demand for stable running costs and fewer hot water repair surprises.
Across the 2482 postcode, most dwellings are separate houses, often three or four bedrooms, which means decent hot water demand from showers, washing machines and dishwashers. Hot water can easily make up a quarter of a home’s electricity use, so choosing an energy efficient hot water system has a real impact on bills. Many homes are now pairing rooftop solar with a modern electric hot water installation or heat pump hot water installation to soak up daytime solar and cut grid imports. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are common choices, alongside options like Thermann or Solahart for those chasing the best hot water system Australia can offer for local conditions.
Typical savings for Main Arm homes moving away from older units look like this:
• Old electric to heat pump: save roughly $350–$700 per year on bills. • Gas to heat pump: save around $300–$600 per year, plus avoid gas connection fees. • Gas to solar hot water: save about $250–$550 per year, depending on usage. • Old electric to modern electric with solar: save around $200–$500 per year using timers or solar diversion.
There have already been 1,118 efficient hot water systems installed in the 2482 area, combining heat pump and solar hot water installation projects. Installations built steadily from just a handful in 2001 to peaks in 2008 and 2009, when well over 250 systems went in across those two years. While recent years show fewer installs annually, the long‑term trend confirms growing local interest in electrification, lower running costs and moving to options like rheem solar hot water, chromagen solar hot water and other efficient technologies. As older tanks reach the end of their life, many households are choosing solar hot water vs electric hot water, or comparing heat pump vs solar hot water, instead of simply replacing like‑for‑like.
Hot Water Rebates, Tariffs & Savings
Right across Main Arm and the wider 2482 area, more people are replacing old gas or resistive electric units with a heat pump hot water system, a newer electric hot water system designed to work with solar, or a roof‑mounted solar hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs can offer a heat pump hot water rebate or solar hot water rebate for certain households, and there may also be an electric hot water system rebate when replacing inefficient models. For Main Arm homeowners, these hot water rebate nsw options can cut the upfront hot water system price / cost by a substantial percentage, bringing premium systems like Sanden heat pump or quality rheem solar hot water within reach.
Once installed, efficient systems often save hundreds of dollars per year, especially when combined with rooftop solar and smart controls. Using timers to run an electric hot water system during solar hours, or using a solar‑diversion controller, can dramatically improve the value of a solar hot water vs electric hot water setup. When rebates and solar work together, payback periods can shrink to just a few years, particularly for the best heat pump hot water system choices that deliver very low running costs.
