Hot water systems in Mokine
Across Mokine and the wider 6401 area, more homes are switching from old gas and electric units to an energy efficient hot water system that is cheaper to run and easier to live with. With an average household size of 2.4 people and most dwellings being separate houses, families and downsizers alike are looking for reliable hot water that will not blow the power bill. For many, upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is the logical next step.
Mokine’s sunshine makes it ideal for efficient hot water. The local climate data shows mean daily solar exposure of around 19.2 MJ/m², which works out to roughly 5.3 kWh of solar energy per square metre per day. That strong solar input supports both a solar hot water heating system on the roof and high performance heat pump hot water, especially when paired with rooftop solar. With around 2,965 occupied private dwellings and a big share of homes owned outright or with a mortgage, many households are in a good position to invest in upgrades that bring long term hot water energy savings.
In a typical Mokine home, hot water can be one of the biggest energy users after heating and cooling. For an average 2–4 person household, choosing the most efficient hot water system can make a real dent in running costs. Local installers are seeing steady interest in heat pump vs solar hot water options, as well as from people wanting to move to an all electric home and compare solar hot water vs electric hot water or electric hot water vs gas hot water. Brands like Rheem, Rinnai, Sanden and Chromagen are common choices, with options ranging from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water, sanden heat pump systems and chromagen solar hot water packages.
For many households, the key question is hot water system price or cost over the life of the unit, not just the sticker. A quality heat pump hot water installation can cut electricity use by up to two thirds compared with an old resistive electric unit, so the heat pump hot water price or cost often pays back quickly. A well designed solar hot water installation can deliver similar savings, especially where there is good roof space and clear northern exposure, and solar hot water price or cost looks even better when you factor in lower bills over 10–15 years. Even a modern electric hot water installation, controlled by timers or solar diversion, can be an energy efficient hot water system when combined with rooftop solar.
To put it in perspective for Mokine households, here are typical annual bill savings many locals can expect when they upgrade from older systems:
• Old electric storage to heat pump hot water system: save around $350–$700 per year. • Gas storage to heat pump hot water: save about $250–$500 per year. • Gas storage to solar hot water system: save roughly $200–$450 per year. • Old electric to modern electric hot water system using rooftop solar: save around $200–$400 per year.
Recent years show how quickly hot water WA is changing. In the 6401 postcode there have already been 848 efficient hot water installations, combining both heat pump and solar hot water systems. Installations climbed strongly from the early 2000s, peaking around 2008–2011, and have remained solid with 30–40 systems going in most years since 2014. Even in 2024 and 2025, dozens more systems are being installed. This steady trend reflects growing local interest in electrification, hot water repair and replacement at end of life, and lower running costs for households in Mokine who are feeling power prices rise.
When an older unit fails, many residents are now upgrading rather than like for like replacing. That might mean a solar hot water tank replacement tied into existing panels, or swapping a gas unit for a sanden heat pump or other best heat pump hot water system options on the market. Others are choosing rheem solar hot water, rinnai solar hot water or chromagen solar hot water packages as a way to lock in long term savings. For those focused on reliability, a carefully sized electric hot water system working with rooftop solar can still be one of the best hot water system Australia wide for simplicity and low maintenance.
