With around 976 occupied dwellings, a high share of separate houses and an average household size of 2.2 people, most homes here use a lot of hot water relative to their income, so cutting running costs really matters.
Wondai’s sunshine is a big advantage. The local weather station records an average solar exposure of about 19 MJ/m² per day – roughly 5.3 kWh/m² – across the year, which strongly supports both a solar hot water heating system and high performance heat pump hot water.

In 4606, most homes are standalone houses with three bedrooms, so hot water demand for showers, washing and cleaning is steady. That makes choosing the most efficient hot water system even more important. A well sized heat pump hot water installation or solar hot water installation can cover the bulk of a family’s hot water energy use, while a quality electric hot water installation paired with rooftop solar can still be very cost effective. Brands like Rheem, Rinnai, Sanden and Solahart are common choices in Queensland, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water, Sanden heat pump units and chromagen solar hot water style systems from other suppliers.
Here’s what typical annual bill savings can look like in Wondai with the right hot water installation:
• Old electric to heat pump hot water system: save around $350–$700 per year
• Gas to heat pump hot water: save about $250–$600 per year

Uptake really picked up around 2007–2010, with 16 installs in 2007 and 10 per year in both 2008 and 2009, and while numbers have been smaller more recently, there are still new systems going in every year, including 3 installs in 2022 and 2 in 2024. This steady trend reflects growing interest in electrification, lower running costs and moving away from gas hot water, particularly as residents look for the best hot water system Australia can offer for regional conditions.
Hot Water Rebates, Tariffs & Savings
For Wondai homeowners, there is strong interest in replacing old gas or electric hot water with efficient options like a heat pump hot water system, a newer electric hot water system or a solar hot water heating system. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively working like an upfront discount off the heat pump hot water price / cost or solar hot water price / cost. On top of that, Queensland hot water rebate QLD programs and occasional state based heat pump hot water rebate or solar hot water rebate offers can further reduce the hot water system price / cost by a substantial percentage.
When you combine rebates with rooftop solar, payback periods on a best heat pump hot water system or quality solar hot water vs electric hot water can be cut to just a few years, especially if you use timers or solar diversion to heat water in the middle of the day. Many households see hundreds of dollars per year in savings compared with electric hot water vs gas hot water or older resistive units, particularly when moving to an energy efficient hot water system like a Sanden heat pump or similar. There are also options for an electric hot water system rebate in some programs, helping households modernise even if they are not ready for solar hot water repair or solar hot water tank replacement just yet.
