With Perth’s variable subtropical climate of hot, dry summers and mild, wet winters, choosing the right hot water system requires careful consideration of a household’s unique needs and usage patterns. The optimal system should reliably deliver sufficient hot water for all residents while keeping energy bills affordable over both the short and long term. Homeowners must weigh upfront purchase and installation costs against projected savings on ongoing electricity, gas or renewable energy consumption when making their selection.

On the Market: Comparing Perth’s Hot Water System Options

Solar Hot Water Systems

Leveraging Perth’s abundant yearly sunlight, solar hot water systems offer an environmentally-friendly solution that can lead to massive long-term savings on bills. Thermosiphon or pumped systems feature roof-mounted solar collectors/panels that harness the sun’s thermal energy to heat water stored in an insulated ground-level or rooftop tank. Though solar hot water systems incur higher initial installation costs, they can slash water heating bills by up to 60% thanks to free renewable solar energy. They’re an ideal option for households committed to shrinking their carbon footprint.

Gas Storage and Instantaneous Hot Water Systems

Natural gas and LPG hot water system Perth are valued for their impressive efficiency of around 75-90% and rapid water heating capabilities from powerful burners. Storage systems heat and store hot water in insulated tanks for on-demand use. Though initial install costs are lower, ongoing gas bills are incurred. Instantaneous systems featuring continuous flow heat water on demand, saving space without a tank but installation may be pricier. Gas systems suit larger households with high demand.

Electric Storage and Instantaneous Hot Water Systems

Electric hot water comprises around 37% of household energy bills nationally, making efficiency paramount. Electric systems either use storage tanks or instant heaters. Storage tanks feature electric heating elements that automatically heat water overnight using off-peak tariffs. Instant models heat as needed but may lack compatibility with solar/PV systems. While electric systems have lower install costs than solar or gas, heating elements make them the least efficient option.

Hybrid Hot Water Systems

Hybrid systems combine the strengths of fuel sources like solar and gas or electric. Linked to both solar collectors and an LPG or electric booster, they maximize renewable solar thermal energy for the bulk of heating but use gas or electric to “top up” the tank on overcast days or during peak winter usage periods. Though upfront system costs run higher, hybrid systems optimize free solar gain.

Heat Pump Hot Water Systems

Heat pumps extract ambient thermal energy from air to heat refrigerant gas which the system then uses to heat water. Considerably more efficient than electrical element water heating, they can be linked to PV panels to run on renewable solar electricity. Though heat pumps have a steep install price, the savings often offset this over time.

Helpful Tips for Selecting the Optimal System

When selecting a hot water system in Perth, key points for homeowners to consider include:
