Dapto’s mean daily solar exposure sits at about 15.7 MJ/m², or roughly 4.4 kWh/m² per day over the year, which is excellent for both a solar hot water system and a modern heat pump hot water system. That sunshine helps a solar hot water heating system pre‑heat your water, and gives heat pumps plenty of free ambient energy to work with. For the many homes here owned outright or with a mortgage, upgrading from older gas or electric hot water to an energy efficient hot water system is a logical next step, with annual hot water energy savings that can easily reach hundreds of dollars per year.
In 2530, most dwellings are three‑ and four‑bedroom homes, so hot water use is a big slice of the power bill. Swapping an old electric hot water system for a quality heat pump hot water system or solar hot water system can cut hot water energy use by 60–75%, especially if you already have rooftop solar. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are common choices locally, alongside options such as Chromagen solar hot water for those wanting a robust solar hot water installation. For some homes, a modern electric hot water system tied to solar can still stack up well, particularly when comparing solar hot water vs electric hot water on a tight budget.
Typical annual bill savings in Dapto look like this:
• Old electric to heat pump: save about $350–$700 per year • Gas to heat pump: save about $250–$550 per year • Gas to solar hot water: save about $250–$600 per year • Old electric to modern electric with solar: save about $200–$500 per year
There have already been around 1,300 efficient hot water installations in the Dapto postcode, covering both heat pump hot water installation and solar hot water installation. Installations peaked around 2009–2010, with more than 560 systems installed over those two years, and there has been a steady flow of new systems every year since.

When people here talk about the best hot water system Australia has to offer, they are usually weighing up heat pump vs solar hot water, or solar hot water vs electric hot water backed by rooftop PV. A key part of the decision is hot water system price and long‑term running cost. Heat pump hot water price can be higher upfront than a basic electric hot water installation, but rebates and bill savings usually deliver a quick payback. Similarly, solar hot water price depends on roof layout and tank size, but a well‑designed rheem solar hot water or chromagen solar hot water system can run for years with minimal solar hot water repair costs.
In NSW, Dapto households can often tap into Federal Small‑scale Technology Certificates (STCs) plus state‑based support to reduce the effective hot water system cost. These incentives act like a hot water rebate nsw, cutting thousands off a quality heat pump hot water system or solar hot water heating system. A heat pump hot water rebate, solar hot water rebate or electric hot water system rebate can trim the upfront heat pump hot water cost or solar hot water price by a substantial percentage, meaning payback periods of just a few years – even faster if you also use timers or solar diversion to run your system when your panels are generating.
If your current unit is ageing, noisy or you are comparing electric hot water vs gas hot water for a renovation, now is a smart time to look at a hot water upgrade. Whether you are leaning towards a Sanden heat pump, Rheem solar hot water, Rinnai solar hot water or another of the best heat pump hot water system options, working with experienced hot water nsw installers matters.
