Hot water systems in Hastings
Across Hastings and the wider 7109 area, more locals 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 an average household size of 2.5 people and more than 3,600 occupied dwellings, reliable and affordable hot water is a big deal for local families, retirees and small businesses alike.
Energy prices keep creeping up, so it makes sense that homeowners who own outright or are paying off a mortgage (around 3,000 households in total) are looking for an energy efficient hot water system that cuts bills and future‑proofs their property. The climate here helps too. Hastings enjoys around 12.9 MJ/m² of solar exposure a day on average – roughly 3.6 kWh/m²/day – which is solid for both a solar hot water heating system and for helping a heat pump hot water system run efficiently, especially when paired with rooftop solar.
Many homes still rely on older gas or off‑peak electric units, which are some of the most expensive ways to heat water. Upgrading to a modern system can deliver substantial Annual Hot Water Energy Savings, particularly for families and the many over‑65s in the postcode who value comfort but want to keep running costs under control. Whether you are weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water, the numbers usually favour going efficient.
In the 7109 area, there have been 219 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation. Installations really took off around 2009–2011, peaking at 55 systems in 2010, and while yearly numbers are smaller now, there is steady interest each year through to 2025. This trend shows a clear shift towards electrification, lower running costs and hot water tas solutions that work with solar rather than against it.
For a typical Hastings home, hot water can be one of the biggest single energy loads. That is why choosing the most efficient hot water system you can afford is so important. Quality brands such as Rheem, Rinnai, Sanden and Thermann are common locally, with options ranging from rheem solar hot water and chromagen solar hot water style systems through to rheem heat pump hot water or a premium sanden heat pump for ultra‑low running costs. Many locals also consider what is the best hot water system Australia wide, or the best heat pump hot water system specifically, before deciding what suits their roof space, budget and household size.
To give you a feel for savings, here are typical annual bill reductions many Hastings households see when they upgrade:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump: $300–$700 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water installation powered by rooftop solar: $250–$500 per year
Actual hot water system price / cost will depend on brand, size and layout. Heat pump hot water price / cost is usually higher upfront than a like‑for‑like electric hot water installation, and solar hot water price / cost is higher again when you include roof collectors and a solar hot water tank replacement. However, the running costs are far lower, especially when you use timers or solar diversion to line up hot water heating with your solar generation.
The good news for Hastings homeowners is that there are several hot water rebate tas options that can soften the upfront cost. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pumps, effectively acting as a point‑of‑sale solar hot water rebate or heat pump hot water rebate. On top of that, state programs and, at times, retailer offers can provide an electric hot water system rebate or extra discounts for swapping out old gas systems. Together these can reduce system cost by a substantial percentage and shorten the payback period to just a few years, especially if you already have solar.
If your current unit is leaking, more than 10 years old, or you are simply tired of high gas bills, now is a smart time to look at a hot water upgrade. Thinking through electric hot water vs gas hot water, or heat pump vs solar hot water, can feel complex, but you do not have to work it out alone. Talk to experienced local installers who specialise in hot water installation and hot water repair, including solar hot water repair and solar hot water tank replacement. With Hastings’ good solar resource, strong interest in sustainability and plenty of all‑electric homes, an energy efficient hot water system can lower your bills, cut emissions and add value.
