Hot water systems in Andergrove
Across Andergrove and the wider 4740 area, more households are shifting to energy efficient hot water systems – especially heat pump hot water, solar hot water and modern electric hot water options. With an average household size of around 2.5 people and more than 30,000 dwellings in the postcode, hot water is a big slice of local power bills. Many families are paying off a mortgage on homes they own, while almost a third of properties are rented, so keeping running costs down matters whether you are an owner occupier or investor.
Upgrading from an old gas or electric hot water system to a modern heat pump hot water system or solar hot water system is a logical next step after rooftop solar. Andergrove’s strong sunshine helps too. The local Mackay weather station records mean daily solar exposure of about 20.7 MJ/m², which is roughly 5.75 kWh/m² per day – excellent for a solar hot water heating system and for efficient heat pump performance. Over a year, that sort of solar resource can translate into substantial hot water energy savings for Andergrove homeowners.
In a suburb with lots of three and four bedroom separate houses, hot water demand is steady all year. Hot water energy use can easily make up 20–30% of a household’s electricity, so choosing the most efficient hot water system you can afford really pays off. Locally, you will see brands like Rheem, Rinnai, Sanden and Thermann on many driveways and rooftops – from rheem solar hot water and rinnai solar hot water systems through to premium sanden heat pump units and versatile Thermann heat pump hot water systems. These are popular choices for anyone chasing the best hot water system Australia can offer in our humid, coastal climate.
Average annual bill savings for Andergrove homes typically fall into these ranges:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water system with solar: $200–$450 per year, depending on solar size and tariffs
Efficient hot water is not new to the 4740 postcode. There have already been 2,216 efficient hot water installations recorded here, including both heat pump and solar hot water installation projects. Installations climbed strongly through the mid‑2000s, peaking around 2009–2011 with more than 200 systems per year, then settled into a steady stream of upgrades. While numbers in 2023–2025 are smaller, they show ongoing interest in electrification, lower running costs and replacing ageing solar hot water tanks before they fail. Each hot water installation or solar hot water tank replacement adds to a growing base of efficient homes across Andergrove.
When it comes to hot water QLD incentives, there is rising interest in switching from gas hot water to electric hot water, or from old resistive units to an energy efficient hot water system such as a heat pump or solar hot water system. Federal Small‑scale Technology Certificates (STCs) help cut the upfront solar hot water price / cost and heat pump hot water price / cost, and there are state‑based heat pump hot water rebate and solar hot water rebate programs that can further reduce a typical hot water system price / cost by a substantial percentage. Some newer electric hot water system rebate offers also encourage households to move away from gas. For many Andergrove families, that means payback periods of just a few years, especially if you combine a heat pump hot water installation or solar hot water installation with rooftop PV and use timers or solar diversion to heat water in the middle of the day.
If you are weighing up heat pump vs solar hot water, or wondering about solar hot water vs electric hot water and electric hot water vs gas hot water, it is worth getting tailored advice. The most efficient hot water system for a busy family might be different to a smaller household or a rental. Options range from rheem heat pump hot water and chromagen solar hot water through to simple electric hot water installation and hot water repair for existing systems.
