Hot water systems in Kerrisdale
Across Kerrisdale and the 3660 postcode, more households are moving away from old gas and power‑hungry cylinders towards energy efficient hot water systems. With most homes here being separate houses and an average household size of around 2.3 people, a well‑sized hot water system can make a real dent in quarterly bills. Many households are on modest incomes, so shifting from older gas or electric hot water to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a practical way to lock in long‑term savings.
Kerrisdale’s climate is well suited to efficient hot water. Nearby Strath Creek records an average of about 16 MJ/m² of solar exposure a day, which is roughly 4.4 kWh/m². That strong sunlight helps a solar hot water heating system perform well year‑round and boosts the efficiency of a heat pump hot water system, especially when it is timed to run during the sunniest parts of the day. For many of the 3,000‑plus dwellings in the 3660 area, upgrading to an energy efficient hot water system can cut hot water energy use by more than half, delivering solid annual hot water energy savings without sacrificing comfort.
In a typical Kerrisdale home, hot water is one of the biggest energy loads after heating and cooling. Families and retirees alike are looking at options such as a rheem solar hot water system on the roof, a Sanden heat pump or other best heat pump hot water system options to replace tired storage tanks. Brands like Rheem and Rinnai are popular for both solar hot water installation and modern electric hot water installation, while Sanden heat pump units are often chosen for ultra‑low running costs. When comparing heat pump vs solar hot water, many locals weigh up roof space, budget, and whether they already have rooftop solar.
Average annual bill savings in Kerrisdale for a well‑planned hot water upgrade can be substantial:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water system: save roughly $300–$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 around $200–$450 per year.
With more than 323 efficient hot water installations already recorded across the 3660 postcode, Kerrisdale is clearly warming to electrification. Installations of heat pump hot water and solar hot water systems have grown strongly since 2020, with noticeable spikes in 2020, 2022 and 2023 as households chased lower running costs and hot water rebate VIC incentives. This trend reflects a growing preference for all‑electric homes, especially as more roofs in the region add solar panels and residents look for the most efficient hot water system to match.
Hot Water Rebates, Tariffs & Savings
Homeowners in Kerrisdale can tap into a mix of Australian Government incentives and Victorian hot water rebate VIC programs when installing an energy efficient hot water system. Federal Small‑scale Technology Certificates (STCs) effectively discount the upfront hot water system price or cost of eligible solar hot water and heat pump systems. On top of that, state‑based solar hot water rebate and heat pump hot water rebate schemes can further reduce the heat pump hot water price or cost or the solar hot water price or cost, sometimes cutting the out‑of‑pocket expense by a substantial percentage. There are also electric hot water system rebate options when shifting away from gas.
For many Kerrisdale homes, these incentives mean a quality rheem heat pump hot water unit, rinnai solar hot water system or chromagen solar hot water setup can pay for itself in just a few years, especially when combined with rooftop solar and smart controls. Using timers or solar‑diversion devices to run a heat pump during the middle of the day can turn it into a highly energy efficient hot water system, slashing grid imports. Over the life of the system, that can mean thousands of dollars saved compared with electric hot water vs gas hot water, and a big cut in emissions.
