With an average household size of around 2.6 people and more than 3,200 families in the postcode, reliable hot water matters every day, from early farm starts to busy family evenings. Rising energy costs and a median household income of about $1,447 a week mean it makes sense to squeeze more value out of every kilowatt.
Weranga is well placed for efficient hot water upgrades. The local solar exposure averages about 19.6 MJ/m² per day – roughly 5.4 kWh/m² – which is excellent for both a solar hot water system and a modern heat pump hot water system. That strong sunshine helps a solar hot water heating system pre‑heat your water, while a heat pump hot water system uses the warm air to run even more efficiently. For many homes, upgrading from an older gas or electric hot water system can cut hot water energy use by more than half, delivering solid Annual Hot Water Energy Savings with every bill.
Most dwellings in the 4405 postcode are separate houses, with more than 3,800 three‑ and four‑bedroom homes, so hot water demand is often medium to high. In these homes, hot water can be one of the biggest single energy loads. That is why more locals are looking closely at heat pump vs solar hot water, and even solar hot water vs electric hot water, to find the most efficient hot water system for their family and budget. Brands like Rheem heat pump hot water units and Sanden heat pump systems are popular for low running costs, while Rheem solar hot water and Rinnai solar hot water options suit properties with plenty of roof space. Chromagen solar hot water is another option when you want a proven solar hot water installation with good efficiency.
Typical bill savings in Weranga for a well‑matched system can look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 a year. • Gas to heat pump hot water: save around $250–$600 a year. • Gas to solar hot water installation: save about $250–$550 a year. • Old electric to modern electric hot water installation combined with rooftop solar: save roughly $200–$500 a year.
In total, around 243 efficient hot water systems – mainly heat pump and solar hot water – have already been installed across the 4405 postcode. Installations ramped up strongly between 2007 and 2011, with peak years like 2009 and 2010 seeing more than 25 systems each year, and there has been steady activity again from 2019 through to 2024. This trend shows growing local interest in electrification, lower running costs and moving away from gas hot water where possible.
Hot Water Rebates, Tariffs & Savings
For Weranga homeowners, there is increasing interest in replacing older gas or electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water system that works alongside rooftop PV. Australian Government Small‑scale Technology Certificates (STCs) can reduce the solar hot water price / cost or heat pump hot water price / cost at the point of sale, while Queensland hot water rebate QLD programs often provide extra support for efficient upgrades. Together, these incentives can cut the upfront hot water system price / cost by a substantial percentage, especially when you are moving to an energy efficient hot water system like the best heat pump hot water system for your size home.
On top of that, there may be an electric hot water system rebate or specific heat pump hot water rebate available at times, further improving payback. Combine rebates with a well‑timed tariff, timers or solar‑diversion, and many Weranga households see payback periods shrink to just a few years, while enjoying hundreds of dollars in savings every year. If your existing unit is ageing, a solar hot water tank replacement or solar hot water repair can also be a smart step before it fails.
