The 3717 postcode, covering Limestone, Flowerdale, Ghin Ghin, Glenburn, Homewood, Killingworth, Murrindindi and Yea and surrounding areas, is home to around 1,749 households. 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 Limestone and the 3717 area, 240 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 Limestone'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 Limestone
Across Limestone and the wider 3717 area, more locals are rethinking their old gas and electric hot water system and switching to energy efficient options. With an average household size of around 2.2 people and many homes owned outright or with a mortgage, hot water upgrades are a simple way for Limestone households to cut running costs without sacrificing comfort. The climate helps too: the Yea weather station records around 16.1 MJ/m² of solar exposure a day, or roughly 4.5 kWh/m², which is ideal for both a modern heat pump hot water system and a quality solar hot water system.
For many Limestone homeowners, moving from older gas or resistive electric units to a newer heat pump hot water system or smart electric hot water system is the logical next step after installing rooftop solar. Hot water can be one of the biggest single energy users in a home, particularly for the many couples and retirees in the postcode, so the annual hot water energy savings from an upgrade can be significant. With a mix of three and four bedroom homes across the 1,400+ occupied dwellings, choosing the right hot water installation size is important to keep showers hot without wasting energy.
In 3717 Limestone, efficient hot water systems are already well established, with 240 heat pump and solar hot water installations recorded to date. Uptake really took off around 2009, when installations jumped to 28 in a single year, and there has been steady interest ever since, with solid growth again from 2020 through to 2024. This trend shows more Limestone households are keen on electrification, lower running costs and getting away from volatile gas prices.
Typical annual bill savings in Limestone for a well designed hot water upgrade look like:
• Old electric to heat pump hot water system: about $400–$800 per year • Gas to heat pump hot water system: about $300–$600 per year • Gas to solar hot water heating system: about $250–$600 per year • Old electric to modern electric hot water installation using rooftop solar: about $200–$500 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are popular for reliable performance, while Sanden heat pump units are often chosen by households chasing the best heat pump hot water system and ultra low running costs. Rinnai solar hot water and Chromagen solar hot water are common choices for a robust solar hot water installation with roof collectors and a well insulated solar hot water tank replacement. Many Limestone homeowners simply want the best hot water system Australia can offer for their budget, balancing hot water system price / cost with long term savings.
When comparing heat pump vs solar hot water, both can be the most efficient hot water system for different homes. A high efficiency heat pump hot water installation suits shaded blocks or homes with big winter demand, while a roof mounted solar hot water heating system can be perfect on sunny, north facing roofs. For some properties, a new electric hot water installation combined with solar PV and a smart timer offers a very energy efficient hot water system that is simple and affordable.
Hot Water Rebates, Tariffs & Savings
Across Limestone VIC, interest in replacing old gas or electric hot water with efficient options is growing quickly. That is helped along by generous Australian Government incentives such as Small-scale Technology Certificates (STCs), plus Victorian schemes that can offer a heat pump hot water rebate, solar hot water rebate and even an electric hot water system rebate in some programs. These hot water rebate VIC offers can effectively cut the upfront heat pump hot water price / cost or solar hot water price / cost by a substantial percentage.
For Limestone households on modest median incomes, these incentives make it far easier to move to an energy efficient hot water system. Many families see hundreds of dollars a year off their bills, and the payback period can be shortened dramatically when rebates and rooftop solar are combined. Smart controls like timers or solar diversion can push more of your hot water use into the middle of the day, improving the economics of solar hot water vs electric hot water, and electric hot water vs gas hot water even further.
If your current unit is more than 10 years old, running out of hot water or needing regular hot water repair, it is a good time to compare options and hot water system price / cost before it fails. Whether you are considering rheem solar hot water, rinnai solar hot water, a Sanden heat pump, Rheem heat pump hot water or Chromagen solar hot water, local specialists can help you choose the right size and technology for your Limestone home.
