Hot water systems in Joondanna
Across Joondanna, more households are swapping old gas units and ageing electric tanks for an energy efficient hot water system that actually suits Perth’s sunny climate. With an average household size of about 2.1 people and more than 11,000 dwellings across 6060, there’s strong demand for reliable hot water that does not send power bills through the roof. Many locals are paying off mortgages or renting, so shifting from an older gas or electric hot water system to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a simple way to lock in long term savings.
Joondanna shares Perth’s excellent solar exposure, with around 19.3 MJ/m² of sunshine a day on average – roughly 5.4 kWh/m². That is ideal for a solar hot water heating system and also boosts the efficiency of a quality heat pump hot water system, especially when paired with rooftop solar. Families and downsizers alike are looking at the annual hot water energy savings on offer when they upgrade, particularly with median household incomes sitting in the mid range and energy costs climbing. In this part of WA, hot water can easily be a quarter of a home’s electricity use, so upgrading is often the next logical step after installing solar panels.
In the 6060 area, there are thousands of separate houses and townhouses plus nearly 1,800 flats and apartments, so there is no single “best hot water system Australia wide” that fits everyone. Smaller Joondanna units might lean towards compact rheem heat pump hot water options or a neat electric hot water installation on an off peak tariff, while larger family homes often look at a roof mounted solar hot water installation with a ground tank. Brands like Rheem, Rinnai and Chromagen solar hot water are common choices for a solar hot water system, while premium systems such as a Sanden heat pump are popular with owners chasing the most efficient hot water system possible.
Average annual bill savings in Joondanna for a well designed hot water upgrade can look like:
• Old electric to heat pump hot water installation: about $350–$700 per year • Gas storage to heat pump: roughly $250–$550 per year • Gas storage to solar hot water installation: around $300–$650 per year • Old electric to modern electric hot water installation with solar: about $200–$450 per year
Since 2001, around 917 efficient hot water systems have been installed across Joondanna and surrounding 6060 suburbs, mainly a mix of heat pump and solar hot water. Installations climbed steadily through the 2000s, peaking around 2010 when more than 190 systems went in, and have continued at a steady rate since, with 15–30 systems most years. That long term trend shows growing local interest in electrification, lower running costs and moving away from gas hot water, especially as more rooftops fill with solar.
Hot Water Rebates, Tariffs & Savings
For Joondanna homeowners, hot water WA rebates and tariffs make the switch even more attractive. Federal 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, WA based programs and retailer offers can provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some schemes. Together, these incentives can trim the heat pump hot water price or solar hot water price by a substantial percentage and shorten payback to just a few years, especially if you already have rooftop solar.
When you compare heat pump vs solar hot water or look at solar hot water vs electric hot water, it is worth factoring in your roof space, shading, tariff options and whether you plan to go all electric. Timers or solar diversion can push more of your hot water use into the middle of the day, turning excess solar into free showers and making your energy efficient hot water system work even harder for you. If you are replacing a failed tank, a fast hot water repair or solar hot water repair can often be combined with a smart upgrade, including solar hot water tank replacement.
If your current unit is old, noisy or running out of hot water, it is a good time to check whether your Joondanna home is ready for a hot water upgrade. Whether you are moving from gas to an electric hot water system, or weighing up heat pump vs solar hot water, working with experienced local hot water installers matters. With Joondanna’s strong solar resource and growing focus on sustainability, an efficient system can cut bills, reduce emissions and future proof your home.
