Hot water systems in Laharum
Across Laharum and the wider 3401 area, more households are swapping old gas and electric units for an energy efficient hot water system that keeps bills down and showers hot. With an average household size of around 2.7 people and most homes being separate houses, there is solid demand for reliable hot water that can handle family life without wasting energy. Median household incomes are steady, but with rising power prices, it makes sense for Laharum locals to look closely at hot water system price and running costs, not just the sticker.
Laharum’s strong sunshine is a big advantage. The local weather station at Mt Stapylton records about 16.7 MJ/m² of solar exposure a day over the year, which works out to roughly 4.6 kWh/m²/day. That is excellent for both a solar hot water system and a modern heat pump hot water system, especially if you already have rooftop solar. Upgrading from older gas or resistive electric hot water to a solar hot water heating system or high efficiency heat pump can deliver serious Annual Hot Water Energy Savings for local homeowners, cutting one of the biggest chunks of household energy use.
In 3401, most dwellings are three or four bedroom homes, which usually means higher hot water demand and a strong case for the most efficient hot water system you can reasonably afford. Many locals are comparing heat pump vs solar hot water, or even solar hot water vs electric hot water, to find the best hot water system Australia can offer for their situation. Brands like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water and premium Sanden heat pump units are all options in the local market, ranging from budget-friendly to top-tier performance.

• Old electric to heat pump hot water system: save roughly $350–$700 per year on bills. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water system with solar: save roughly $300–$650 per year.
Recent data shows 279 efficient hot water installations (heat pump and solar hot water installation combined) across the 3401 postcode. Installations jumped sharply around 2008–2011, with peak years like 2008 and 2009 seeing over 70 systems between them, and there has been a steady stream of upgrades each year right through to 2024 and 2025. This long-term trend shows growing local interest in hot water VIC electrification, lower running costs and cleaner options than bottled or mains gas.
When you are weighing up a heat pump hot water installation versus a solar hot water installation or an efficient electric hot water installation, rebates make a real difference. Federal Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. On top of that, the Victorian hot water rebate VIC programs can offer a heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate for certain all-electric upgrades. Together, these incentives can cut the effective heat pump hot water price or solar hot water price by a substantial percentage, bringing quality systems within reach for many Laharum households.
For many homes, that means the energy efficient hot water system upgrade can pay back in just a few years, especially when paired with rooftop solar and smart controls like timers or solar diversion. Shifting from electric hot water vs gas hot water to a modern heat pump or solar setup can also reduce exposure to volatile gas tariffs.
