Mettler is well suited to a solar hot water heating system or heat pump. The local weather station records an average of about 16.2 MJ/m² of solar exposure a day over the year, which works out to roughly 4.5 kWh/m² per day. That strong sunlight supports both solar hot water installation and efficient heat pump hot water installation, especially when paired with rooftop solar. With many homes owned outright or with a mortgage, and a good mix of families and older residents, there is growing interest in replacing ageing cylinders and gas units with the most efficient hot water system people can reasonably afford.
In the 6328 postcode, efficient hot water systems are slowly but surely appearing. With 151 occupied private dwellings and 371 residents, hot water is a big slice of household energy use, particularly for larger three and four bedroom homes. Many properties are still on older gas or resistive electric hot water, so the opportunity for community hot water energy savings is significant. A well sized solar hot water system or quality heat pump can cover most of a typical family’s showers, washing and kitchen use, especially when daytime loads are shifted to match solar production.
Typical annual bill savings in Mettler look like this:
• Upgrading an old electric to a heat pump hot water system: about $350–$650 per year. • Switching from gas to heat pump: roughly $250–$500 per year. • Switching from gas to a solar hot water system: around $300–$600 per year. • Replacing an old electric with a modern electric hot water system powered by rooftop solar: about $250–$500 per year.
Brands like Rheem and Rinnai are popular for both electric hot water installation and solar hot water installation, offering options such as Rheem solar hot water, rheem heat pump hot water and rinnai solar hot water. For those chasing the best heat pump hot water system, premium units like Sanden heat pump models are well regarded for efficiency and quiet operation, while Chromagen solar hot water provides reliable solar hot water tank replacement options.

Recent installs in Mettler show this shift in action. There have been 45 efficient hot water installations recorded in the area, combining heat pump hot water and solar hot water systems. The early 2000s saw small bursts of activity, with peaks in 2002, 2004, 2006 and 2008, followed by a steady trickle of systems each year right through to 2023. While numbers are modest, they reflect growing interest in electrification, lower running costs and moving towards solar hot water vs electric hot water or heat pump vs solar hot water as people replace old units at end of life.
Even with a relatively small population, hot water WA upgrades are firmly on the radar. Rising gas prices and ageing cylinders mean more households are comparing electric hot water vs gas hot water, solar hot water vs electric hot water, and asking about heat pump hot water price / cost and solar hot water price / cost. For many, the decision comes down to upfront hot water system price / cost versus savings and reliability, along with the availability of a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate.
Hot Water Rebates, Tariffs & Savings
For Mettler homeowners, a range of Australian Government incentives and state-based hot water rebate WA programs can bring the cost of a new energy efficient hot water system right down. Small-scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, Western Australia has targeted schemes from time to time that support efficient electric and heat pump upgrades, especially when replacing old electric storage or gas units. When you combine these with competitive tariffs and smart use of timers or solar diversion, your payback period can shrink to just a few years, with hundreds of dollars a year shaved off bills.
In practice, that means a quality solar hot water system or heat pump hot water system can often cost far less than people expect once rebates are applied. Discounts can cover a substantial percentage of the installed price, particularly for larger families with high usage. Using off-peak or solar-friendly tariffs, and running your hot water system when your rooftop solar is producing, can turn your new unit into a powerful energy saver and make it one of the most efficient hot water system choices available.
If your current unit is more than ten years old, running out of hot water, or you are simply tired of high gas or power bills, it is a good time to see whether your Mettler home is ready for a hot water upgrade. Whether you are considering a solar hot water heating system, a high performance heat pump, or a well matched modern electric hot water system, working with experienced local hot water installers is essential. With Mettler’s strong solar resource and growing interest in sustainability, an efficient hot water system can cut bills, reduce emissions and future proof your home.
