With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Eildon and the 3713 area, 65 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Eildon's climate delivering an average of 4.5 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Eildon
In Eildon, more locals are swapping old gas and electric units for modern, energy efficient hot water systems that suit our lifestyle and climate. With around 466 occupied dwellings, a high share of homes owned outright and an average household size of just 1.9 people, many residents are at the perfect stage to upgrade to a hot water system that is cheaper to run and easier to live with. Rising energy costs bite harder when you are on a fixed income, so it makes sense that Eildon’s older population is looking closely at options like a heat pump hot water system, solar hot water system and efficient electric hot water system.
Eildon’s sunshine is a real asset. The Lake Eildon weather station records average annual solar exposure of about 16.1 MJ/m² per day, which is roughly 4.5 kWh/m² of usable energy. That strong solar resource helps a solar hot water heating system deliver excellent performance and supports efficient operation for a quality heat pump hot water installation. For homeowners who have already invested in rooftop solar, pairing panels with a modern electric hot water installation or a rheem heat pump hot water unit can turn excess daytime solar into free showers. Moving from older gas or resistive electric units to the most efficient hot water system options can unlock substantial annual hot water energy savings for Eildon households.
Across the 3713 postcode there have already been 65 efficient hot water installations, mainly heat pump and solar hot water installation projects. The big surge in 2008 and 2009, followed by steady installs through the 2010s and new systems going in again from 2020 to 2025, shows a clear, long term trend towards electrification and lower running costs. Many homes here are two or three bedroom separate houses, so demand is steady but not extreme, making a compact sanden heat pump or evoheat style unit an ideal fit. Brands like Rheem and Rinnai are common choices for those wanting the best hot water system Australia can offer in a regional setting, with options ranging from rheem solar hot water and rinnai solar hot water systems through to robust electric hot water system replacements.
When people in Eildon start comparing heat pump vs solar hot water, they usually also look at solar hot water vs electric hot water and even electric hot water vs gas hot water. The right choice depends on roof space, budget and whether you already have solar PV. Typical hot water system price ranges vary, but a quality energy efficient hot water system can often cut hot water use from around a quarter of your electricity bill to a fraction of that. As a guide, realistic average annual bill savings for local upgrades might look like:
• Old electric to heat pump: $400–$700 per year • Gas to heat pump: $300–$600 per year • Gas to solar hot water: $250–$500 per year • Old electric to modern electric with solar: $250–$450 per year
Over time that easily outweighs the initial heat pump hot water price or solar hot water price, especially if you are replacing a failed unit or doing a solar hot water tank replacement at the same time as other works.
Hot Water Rebates, Tariffs & Savings
There is growing interest in Eildon in replacing ageing gas or electric units with efficient hot water options. Federal incentives through Small scale Technology Certificates help reduce the upfront solar hot water cost or heat pump hot water cost, and VIC based programmes can add a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for eligible homes. For many Eildon residents, these hot water rebate VIC schemes can effectively knock a substantial percentage off the installed hot water system price. That shortens payback, especially when you combine rebates with solar PV, smart tariffs, timers or solar diversion controls so the system heats water when your panels are generating. The result is a genuinely energy efficient hot water system that can save hundreds of dollars a year while cutting emissions.
If your existing unit is more than ten years old, running on gas, or you keep needing hot water repair visits, it is worth checking whether your Eildon home is ready for a hot water upgrade. Whether you are weighing up heat pump vs solar hot water, considering rheem solar hot water, rinnai solar hot water, sanden heat pump options or looking for solar hot water repair, working with experienced hot water VIC installers matters. With Eildon’s strong solar resource and growing focus on sustainability, the right system can reduce bills, cut carbon and future proof your home.
