Hot water systems in Coolbellup
Across Coolbellup and the wider 6163 area, more households are swapping old gas units and clunky cylinders for modern, energy efficient hot water systems. With an average household size of about 2.3 people and more than 21,000 occupied dwellings in the postcode, reliable hot water is essential – but so is keeping power bills under control. Many families and downsizers here are looking at a heat pump hot water system, a solar hot water system or a modern electric hot water system as the logical next step in cutting running costs.
Coolbellup’s climate is ideal for efficient hot water. Nearby Murdoch records an average annual solar exposure of around 19.2 MJ/m² per day – roughly 5.3 kWh/m² of sunshine – which is excellent for both a solar hot water heating system and high performance heat pump hot water. When you pair that with median household incomes around $1,638 a week and solid home ownership levels (over 15,000 homes owned outright or with a mortgage), upgrading from old gas or off‑peak electric hot water makes sense as a long term investment. Annual hot water energy savings can easily reach hundreds of dollars a year for a typical Coolbellup family.
In the 6163 area, most homes are separate houses with three or four bedrooms, so hot water demand is steady – morning showers, evening baths, loads of washing. A well sized hot water system can be one of the biggest contributors to lowering overall household energy use. Many locals are comparing heat pump vs solar hot water, or even solar hot water vs electric hot water, to find the most efficient hot water system for their roof space, budget and tariff. Brands like Rheem and Rinnai are popular for both rheem solar hot water and rinnai solar hot water setups, while sanden heat pump and Thermann style units are often chosen when people want the best heat pump hot water system on the market.
Typical bill savings for Coolbellup homes can look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas storage to heat pump hot water system: save around $250–$600 per year. • Gas storage to solar hot water installation: save about $300–$650 per year. • Old electric to modern electric hot water installation with solar PV: save roughly $250–$500 per year, depending on usage and tariffs.
Over time, these savings can offset the hot water system price / cost, especially when you factor in rebates and the lower heat pump hot water price / cost of ownership. Many locals also look closely at solar hot water price / cost, including solar hot water tank replacement versus a full system changeover. Choosing recognised brands such as rheem heat pump hot water, sanden heat pump or chromagen solar hot water helps ensure you are getting what many consider the best hot water system Australia can offer in terms of efficiency and reliability.
