Local data shows 3,764 efficient hot water systems have already been installed in the 4350 postcode, including both heat pump and solar hot water installation projects. Installations climbed steadily through the 2000s, peaking around 2010–2011, and while numbers dipped after the early boom, recent years have seen consistent new systems going in as more residents focus on electrification and lower running costs. This trend reflects growing interest in options like a heat pump hot water system or solar hot water heating system as people compare heat pump vs solar hot water and even solar hot water vs electric hot water for their home.
For a typical Harristown family using a three or four bedroom home, hot water is often the second largest energy load after heating and cooling. Switching from an old storage electric hot water system to the best heat pump hot water system you can reasonably afford, or to a quality solar hot water system, can dramatically cut usage. Well-known brands such as Rheem heat pump hot water units, Sanden heat pump systems, and roof-mounted solar from Rheem solar hot water or Rinnai solar hot water are all seen across the area, alongside options like Chromagen solar hot water in nearby suburbs. Many households also look at modern electric hot water installation paired with rooftop solar, which can be a smart move when you already have PV.
When people ask about hot water system price or cost in Harristown QLD, the answer depends on size, technology and whether you need a solar hot water tank replacement or a full hot water installation. As a rough guide, efficient systems usually cost more upfront but much less to run. Typical annual bill savings can look like:
• Replacing an old electric hot water system with a heat pump hot water system: around $350–$700 a year. • Swapping gas hot water to a heat pump hot water system: roughly $250–$500 a year. • Moving from gas to a solar hot water system: about $300–$600 a year. • Upgrading an old electric unit to a modern electric hot water system powered by rooftop solar: often $250–$500 a year, depending on usage.
In practice, the most efficient hot water system for your Harristown home might be a high-performance heat pump like a Sanden heat pump or a quality solar hot water heating system from Rheem or Rinnai. Many locals also look for the best hot water system Australia can offer that fits their budget, comparing heat pump hot water price or cost and solar hot water price or cost against long-term savings. If your existing unit is failing, a fast hot water repair or solar hot water repair can tide you over, but it is often worth weighing that spend against a full hot water upgrade.
Hot Water Rebates, Tariffs & Savings
All this interest in hot water QLD wide is helped by generous incentives. Federal Small-scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, cutting the upfront cost of eligible systems.

Together, these hot water rebate QLD schemes can slash the installed price by a substantial percentage and shorten payback times to just a few years, especially if you run your system on a timer or use solar diversion so it heats when your PV is generating.
For many Harristown households, electric hot water vs gas hot water is now an easy choice: efficient electric options, particularly heat pumps and solar, usually win on running costs and emissions. A well-sized, energy efficient hot water system can trim hundreds off your annual bills, help future-proof your home against gas price rises, and support a move towards an all-electric home.
