Over the life of the unit, annual hot water energy savings can easily add up to thousands of dollars, especially for retired couples and families on fixed incomes.
Across the 3639 postcode there are 302 dwellings but only 209 are occupied, and a large share are owned outright. That means many Barmah homeowners are in a good position to plan ahead and replace ageing systems before they fail. A modern electric hot water system paired with rooftop solar, or a quality rheem heat pump hot water unit, can dramatically cut running costs compared with electric hot water vs gas hot water setups. Brands like Rheem, Rinnai and Sanden heat pump systems are popular choices for those chasing the most efficient hot water system, while rinnai solar hot water and chromagen solar hot water units are common for households wanting a proven solar hot water installation.
In Barmah 3639, efficient hot water system sizes are usually chosen around typical 2–3 bedroom homes, with hot water demand driven by showers, laundry and kitchen use rather than large families. Hot water energy use can still be one of the biggest loads in the house, so upgrading pays off. Typical annual bill savings for local upgrade scenarios look like this:
• Old electric to heat pump hot water system: about $400–$800 per year • Gas to heat pump hot water: about $300–$600 per year • Gas to solar hot water system: about $250–$550 per year • Old electric to modern electric hot water installation with solar: about $250–$500 per year
For many, the question is heat pump vs solar hot water. A heat pump hot water installation tends to be simpler and works well even on cloudy days, while a solar hot water vs electric hot water upgrade with roof collectors can deliver excellent summer performance. Solar hot water price / cost and heat pump hot water price / cost depend on brand and size, but rebates and incentives can narrow the gap. A good installer will walk you through the true hot water system price / cost over the life of the unit, not just the sticker.
Recent data shows 25 efficient hot water systems have already been installed in the 3639 area, combining heat pump and solar hot water installations. Uptake has come in waves, with small bursts in the early 2000s, a lift around 2015–2016, and another rise in 2022.

Hot Water Rebates, Tariffs & Savings
Around Barmah, more homeowners are replacing old gas or electric units with efficient options like a heat pump hot water system, a new electric hot water system or a solar hot water heating system. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively creating a solar hot water rebate or heat pump hot water rebate that reduces upfront cost. Victoria also offers additional state‑based support that can act as a hot water rebate vic for qualifying heat pump and solar systems, and in some cases an electric hot water system rebate when moving away from inefficient models.
These discounts can trim the installed solar hot water price / cost or heat pump hot water price / cost by a substantial percentage, often cutting payback times to well under 10 years – faster if you already have solar. Typical households can save hundreds of dollars a year on bills with the right hot water installation, especially when timers or solar‑diversion controls are used to heat water during sunny periods. For older systems nearing the end of their life, a planned solar hot water tank replacement or electric hot water installation with smart controls can be a wise, future‑proof move.
