The local climate is perfect for efficient hot water. Belmont’s weather station records mean daily solar exposure of about 17 MJ/m², or roughly 4.7 kWh/m² per day over the year. That strong sunlight helps a solar hot water system or heat pump hot water system perform really well, especially when paired with rooftop solar. Upgrading from an older gas or electric hot water system to a modern heat pump hot water or solar hot water heating system is a logical next step for Marks Point homeowners looking for lower running costs and solid annual hot water energy savings.
In a suburb with a high share of separate houses and a good mix of families and retirees, hot water demand is steady all year. Many homes still run gas or older resistive electric hot water, even though the most efficient hot water system options today are heat pumps and well‑designed solar hot water vs electric hot water setups. Brands like Sanden heat pump and Rheem heat pump hot water are popular for low‑running‑cost upgrades, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices when people want to make the most of the Lake Macquarie sunshine.
Average annual bill savings from a smart hot water installation in Marks Point can be significant:
• Old electric hot water system to heat pump hot water system: save around $350–$700 per year. • Gas hot water to heat pump hot water: save roughly $250–$600 per year. • Gas hot water to solar hot water system: save about $200–$500 per year. • Old electric to modern electric hot water installation with solar diversion: save around $200–$450 per year.
Local data shows 1,361 efficient hot water systems (heat pump and solar hot water installations) have already gone in across the 2280 postcode. Installations jumped sharply around 2009–2011, eased off, and have picked up again recently, with 69 systems in 2023 and more underway in 2024–2025. That steady growth reflects rising interest in electrification, lower running costs and choosing the best hot water system Australia has to offer for Marks Point conditions.
When comparing heat pump vs solar hot water, or solar hot water vs electric hot water, it helps to look at both running costs and upfront hot water system price. A typical heat pump hot water price or cost is now offset by generous rebates, and a well‑sized solar hot water price or cost can be reduced with federal incentives. Even modern electric hot water installation can make sense when paired with solar and smart timers, particularly if you are moving from electric hot water vs gas hot water and want a simple all‑electric home.
Hot Water Rebates, Tariffs & Savings
Around Marks Point, more people are replacing old gas or electric units with efficient options such as a heat pump hot water system, a new electric hot water system with timers, or a roof‑mounted solar hot water heating system. Homeowners can usually tap into Australian Government Small‑scale Technology Certificates (STCs), which act like a discount on eligible systems, as well as state‑based hot water rebate NSW programs that target efficient upgrades. Together, these can cut the upfront hot water system price or cost by a substantial percentage, especially for qualifying heat pump hot water installation and solar hot water installation.
There are also specific incentives like a solar hot water rebate, heat pump hot water rebate and, in some cases, an electric hot water system rebate when you are moving away from gas. For many Marks Point households, that means a payback period of only a few years, particularly if you use timers or solar‑diversion to heat water when your PV system is exporting. Over the life of the system, that can mean thousands of dollars saved, plus lower emissions from an energy efficient hot water system.
If your current unit is due for solar hot water tank replacement, keeps running out of hot water, or you are facing another hot water repair, it is worth checking whether a new heat pump, solar hot water system or efficient electric hot water system could be a smarter move.
