Hot Water Systems in Notting Hill
The 3168 postcode, covering Notting Hill and Clayton and surrounding areas, is home to around 8,606 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 Notting Hill and the 3168 area, 690 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.

Hot water systems in Notting Hill
In Notting Hill, more households are swapping old gas and electric units for an energy efficient hot water system that actually suits modern living. With an average household size of about 2.5 people and a young median age of 28, many locals are either setting up their first place or upgrading older homes and apartments. Rising energy costs and solid solar exposure of around 4.1 kWh/m² per day on average make heat pump hot water, solar hot water and efficient electric hot water system options a smart next step.
Across the 7,150 occupied dwellings in 3168, there is a big mix of separate houses, townhouses and flats, plus a high proportion of rentals. That means hot water installation choices need to be flexible – from compact electric hot water installation in units through to family-sized solar hot water systems on larger roofs. Upgrading from older gas hot water to a modern heat pump hot water system, or from a tired electric cylinder to a solar hot water heating system, can cut annual hot water energy use dramatically. For many Notting Hill homes, hot water is one of the biggest single energy loads, so the potential hot water energy savings are significant.
Notting Hill’s climate gives solar and heat pump technology a real boost. With mean daily solar exposure supporting both roof-mounted panels and efficient compressors, a well-designed solar hot water system or heat pump hot water installation can comfortably meet everyday demand. Brands like Rheem solar hot water and Rinnai solar hot water are common choices for those wanting a reliable solar hot water installation, while Sanden heat pump and Rheem heat pump hot water units are popular where roof space is tight or shading is an issue. These systems are often rated among the best heat pump hot water system options and are frequently shortlisted when people search for the best hot water system Australia wide.
For a typical 3168 home, the hot water system price or cost depends on size, brand and whether you go for a heat pump hot water system, solar hot water vs electric hot water, or a simple electric hot water system replacement. As a rough guide, many locals see average annual bill savings like:
• Old electric to heat pump hot water: $350–$700 per year • Gas to heat pump: $250–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water with solar PV: $200–$450 per year
With 690 efficient hot water systems already installed in the Notting Hill postcode, there is clear momentum. Installations were modest in the early 2000s, then picked up sharply around 2014, and have remained steady through to 2024–2025. That growth in heat pump and solar hot water repair and replacement work reflects a broader local shift towards electrification, lower running costs and more sustainable homes. Many residents now pair a solar hot water tank replacement or electric hot water installation with existing rooftop solar to create the most efficient hot water system possible.
Hot Water Rebates, Tariffs & Savings
Notting Hill households are increasingly comparing heat pump vs solar hot water and even electric hot water vs gas hot water when their old unit fails. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump upgrades, effectively acting as an upfront discount. On top of that, Victorian hot water rebate VIC programs can offer a separate heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when replacing inefficient models. Together, these hot water rebate VIC schemes can reduce the effective heat pump hot water price or cost or solar hot water price or cost by a substantial percentage, often shaving years off the payback period.
By using timers, smart controls or solar diversion, many Notting Hill homes push even more load into the middle of the day, increasing the value of their solar and turning their new energy efficient hot water system into a quiet workhorse that trims hundreds of dollars a year from bills.
If your current unit is ageing, noisy or running on gas, this is a good time to check whether your Notting Hill home is ready for a hot water upgrade. Whether you are considering a heat pump hot water system, a solar hot water system or a modern electric hot water system paired with solar, working with experienced hot water VIC installers like us helps you choose the right size, technology and tariff.
