Hot water systems in Allanooka
Across Allanooka and the wider 6525 area, more households are moving away from old gas and power‑hungry electric units and upgrading to an energy efficient hot water system. With an average household size of about 2.2 people and a big share of homes owned outright or with a mortgage, many locals are looking for long‑term savings rather than short‑term fixes. Power prices keep rising, so switching to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the obvious next step.
Allanooka is well suited to efficient hot water technology. The local solar exposure averages around 20.3 MJ/m² a day – roughly 5.6 kWh/m² – which is excellent for both a solar hot water heating system and high‑performance heat pump hot water. That strong sun, combined with a slightly older population (median age in the 50s) and more than 1,400 occupied private dwellings, means there is steady demand for reliable, low‑maintenance hot water installation and hot water repair rather than constant tinkering with old gas systems.
In Allanooka 6525, detached homes dominate, so there is usually good roof space for solar hot water installation or a compact outdoor spot for heat pump hot water installation. Hot water can be one of the biggest single energy users in the home, so upgrading from an older electric hot water system or gas unit can make a noticeable dent in quarterly bills. Many locals are comparing 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 household size and budget.
Typical bill savings in Allanooka for an average home can look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year • Gas to heat pump hot water: save roughly $250–$600 per year • Gas to solar hot water system: save about $300–$650 per year • Old electric to modern electric hot water installation with rooftop solar: save around $250–$550 per year
Brands like Rheem, Rinnai, Sanden and Thermann are common in the local market, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water and premium sanden heat pump units. Many of these are contenders for the best hot water system Australia has to offer, and some models regularly appear on shortlists for the best heat pump hot water system thanks to their low running costs and long warranties. When a solar hot water tank replacement is needed, locals often take the opportunity to compare solar hot water price / cost against heat pump hot water price / cost and an efficient electric hot water installation, taking into account the hot water system price / cost over the full life of the unit.
Allanooka has already seen 729 efficient hot water systems installed, including both heat pump and solar hot water systems. Installations climbed steadily through the 2000s, peaking around 2009–2014, and there has been a consistent trickle of new installs each year right through to 2025. That pattern shows ongoing interest in electrification, lower running costs and an energy efficient hot water system that works well with existing rooftop solar. As more homes add PV, hot water WA customers are increasingly using timers or smart controls so their electric or heat pump units heat mainly during solar hours.
Hot Water Rebates, Tariffs & Savings
For Allanooka homeowners, generous incentives help bring the heat pump hot water price / cost or solar hot water price / cost down to something very competitive with a basic electric unit. Federal Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, and there are state‑based hot water rebate WA programs that effectively act as a heat pump hot water rebate or solar hot water rebate on selected models. Some newer electric hot water systems can also qualify under broader energy efficiency schemes, acting like an electric hot water system rebate when you move away from gas. Between STCs and state support, it is common to see the upfront cost cut by 20–40%, with many Allanooka households then saving hundreds of dollars a year on bills. Combine rebates with rooftop solar and smart controls, and the payback period on a new hot water system can shrink significantly.
If you are weighing up electric hot water vs gas hot water, or comparing heat pump vs solar hot water for your Allanooka home, now is a good time to look closely at your options. With strong sun, solid local interest in sustainability and a clear trend towards all‑electric homes, upgrading to an energy efficient hot water system can reduce bills, cut emissions and future‑proof your place. To make the most of the available hot water rebate WA programs and choose between rheem solar hot water, rinnai solar hot water, sanden heat pump, rheem heat pump hot water or other chromagen solar hot water style systems, it pays to work with experienced local hot water installers who specialise in heat pump and solar hot water repair and installation.
