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 Dunnstown and the 3352 area, 1,457 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 Dunnstown's climate delivering an average of 4.3 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 Dunnstown
Across Dunnstown and the wider 3352 area, more households are rethinking their old gas or electric hot water system and moving to efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With power prices rising and many families aiming for all‑electric homes, upgrading your hot water installation is one of the easiest ways to cut bills without sacrificing comfort.
Dunnstown’s mostly separate houses and family homes (over 6,300 occupied private dwellings and an average household size of 2.8 people) mean strong demand for reliable hot water every morning and night. Median household incomes are solid for a regional area, but no one wants to waste money heating water inefficiently. The local climate helps too: the Kirks Reservoir weather station records average annual solar exposure of about 15.3 MJ/m² per day, or roughly 4.25 kWh/m² per day. That level of sunshine supports both a solar hot water heating system and high‑efficiency heat pump hot water, especially when paired with rooftop solar.
In a typical Dunnstown three‑ or four‑bedroom home, hot water can be one of the biggest energy users. Switching from an older electric hot water system or gas unit to an energy efficient hot water system can quickly pay off. Many locals are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, to find the most efficient hot water system for their household size and roof space. Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Solahart or Chromagen solar hot water are common choices when people compare the best hot water system Australia wide.
Average annual savings will vary, but realistic ranges for Dunnstown homes look like:
• Old electric to heat pump hot water installation: save around $350–$700 per year on bills. • Gas to heat pump hot water: save roughly $250–$600 per year, depending on gas tariffs. • Gas to solar hot water installation: save around $300–$650 per year. • Old electric to modern electric hot water installation with solar: save about $250–$550 per year by using daytime solar.
Over time, these savings easily outweigh the hot water system price / cost. A premium heat pump hot water price / cost or solar hot water price / cost can look high on paper, but rebates and lower running costs quickly shrink the payback period.
Efficient hot water is already taking off locally. In the 3352 postcode, there have been 1,457 efficient hot water installations to date, combining both heat pump and solar hot water installation projects. Install numbers were modest in the early 2000s, then surged around 2008–2011, with peaks of 206 systems in 2009 and strong years again in 2019 and 2020. Recent installations in 2023–2025 show steady ongoing interest as more Dunnstown households look to electrification, lower running costs and hot water repair or solar hot water repair instead of replacing like‑for‑like gas. Many are also tackling solar hot water tank replacement at the same time as upgrading to more efficient technology.
Hot Water Rebates, Tariffs & Savings
For hot water VIC households, federal Small‑scale Technology Certificates (STCs) and state‑based schemes can significantly reduce the upfront hot water system price / cost. Eligible Dunnstown homeowners can often claim a solar hot water rebate or heat pump hot water rebate, and in some cases an electric hot water system rebate when replacing old gas or resistive electric units. These incentives can effectively cut the installed cost by a substantial percentage, especially for systems like Rheem solar hot water or a high‑efficiency Sanden heat pump. When you combine rebates with rooftop solar, smart tariffs, timers or solar‑diversion controls, many homes see hundreds of dollars per year in savings and much shorter payback times on their energy efficient hot water system.
If you live in Dunnstown and your current unit is older, noisy or needing frequent hot water repair, now is a good time to check whether a heat pump hot water system, solar hot water system or modern electric hot water installation could suit your home.
