Hot water systems in Hastings
Across Hastings, more homeowners are rethinking their old gas and electric hot water system and switching to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With around 4,305 occupied dwellings and an average household size of 2.3 people, hot water is a big chunk of local energy use, especially for families and retirees on the Peninsula. For many households with mortgages around $1,700 a month and median household income of about $1,211 a week, trimming power bills with a more energy efficient hot water system just makes sense.
Hastings enjoys strong sunshine, with mean daily solar exposure of about 15.1 MJ/m² – roughly 4.2 kWh of solar energy per square metre per day across the year. That level of solar exposure is ideal for both a solar hot water heating system and a high-quality heat pump hot water installation, because there is plenty of free energy in the air and on the roof to tap into. Upgrading from older gas or off-peak electric units to the most efficient hot water system can deliver substantial Annual Hot Water Energy Savings for Hastings homeowners, especially when paired with rooftop solar.
In postcode 3915, most homes are separate houses with two to four bedrooms, so hot water demand is steady but predictable. Many properties are owned outright or with a mortgage, which makes long-term savings from a solar hot water installation or heat pump hot water installation particularly attractive. Local installers are seeing solid uptake of brands like Rheem heat pump hot water units, Sanden heat pump systems and roof-mounted options such as Rinnai solar hot water and Chromagen solar hot water, chosen for reliability and strong performance in coastal conditions. These sit alongside quality electric hot water installation options for homes wanting to go all-electric.
Typical bill savings in Hastings for efficient hot water upgrades can look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas to heat pump hot water system: $250–$600 per year • Gas to solar hot water system: $250–$650 per year • Old electric to modern electric with solar: $200–$500 per year
Over time, those savings help offset the hot water system price and ongoing hot water repair costs, especially if you are comparing heat pump vs solar hot water or weighing up solar hot water vs electric hot water. Local households are also replacing ageing cylinders with solar hot water tank replacement options or upgrading to the best heat pump hot water system they can afford to future-proof their home.
Hastings already has 440 efficient hot water systems installed, combining heat pump and solar hot water systems. Installations grew strongly from the mid-2000s, peaking around 2009–2010, with another lift in 2020 and solid numbers again in 2023. This steady trend in yearly installations shows growing local interest in electrification, lower running costs and moving towards the best hot water system Australia can offer for coastal towns. As more homes add solar, pairing it with an energy efficient hot water system is becoming the logical next step.
Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in hot water VIC upgrades as Hastings households look to replace old gas or electric units with efficient options. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively reducing the upfront solar hot water price or heat pump hot water price. On top of that, state-based heat pump hot water rebate and solar hot water rebate programs, plus electric hot water system rebate offers in some schemes, can cut the overall hot water system cost by a substantial percentage for eligible homes. For many families, that means payback periods of only a few years, especially when timers or solar diversion are used so the system runs when rooftop solar is producing. Typical savings from an efficient hot water upgrade can easily reach hundreds of dollars per year, particularly when comparing electric hot water vs gas hot water on current tariffs.
