Hot water systems in Shalvey
Across Shalvey and the wider 2770 area, more households are shifting from old gas and electric units to an energy efficient hot water system that can actually keep bills down. With an average household size of around three people and more than 18,700 occupied dwellings in the postcode, hot water demand is high, especially for busy families. At the same time, power prices keep rising while many locals are juggling median household incomes of about $1,326 a week, so it makes sense that heat pump hot water, solar hot water and modern electric hot water options are getting so much attention.
Shalvey is well suited to efficient hot water upgrades. The local solar exposure averages about 16.1 MJ/m² per day, which is roughly 4.5 kWh of sunlight energy each day across the year. That strong sun helps a solar hot water system or solar hot water heating system perform reliably, and also supports a heat pump hot water system that runs cheaply on daytime solar power. With a lot of standalone houses and many homes owned with a mortgage, upgrading from older gas or resistive electric units to the most efficient hot water system available is a logical next step, cutting running costs year after year.
Across 2770, families tend to have three bedrooms or more, so showers, laundry and dishwashing can make hot water one of the biggest energy users in the home. Swapping an old electric hot water system for a new heat pump hot water system or quality solar hot water system can dramatically reduce that load. Brands like Sanden heat pump units and Rheem heat pump hot water systems are popular for households wanting premium efficiency, while rheem solar hot water, rinnai solar hot water and chromagen solar hot water systems are common choices for roof-mounted solar hot water installation and solar hot water tank replacement when older tanks rust out.
Typical annual savings depend on what you are upgrading from and to, but many Shalvey homes can expect:
• Old electric to heat pump: around $400–$800 a year off hot water bills. • Gas to heat pump: roughly $300–$600 a year in savings. • Gas to solar hot water: around $250–$550 a year, depending on usage. • Old electric to modern electric with rooftop solar: about $250–$500 a year.
These ranges will vary with your tariff, how many people live in the home and the exact hot water system price / cost, but they give a good guide to what is possible.
In Shalvey and the surrounding suburbs, there have already been 915 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation.
