Types of Hot Water Systems in Perth

In Perth choosing the right hot water system is crucial for both comfort and cost efficiency. The city’s unique climate and energy options offer a range of systems to consider.

Let’s delve deeper into each type to help you make an informed decision.

Electric Hot Water Systems in Perth


Electric hot water systems are among the most straightforward and commonly used types. They use an electric element to heat the water, which is then stored in a tank for later use.


  • Ease of Installation: These systems are generally easier and quicker to install than other types.
  • Lower Upfront Cost: Electric systems are usually cheaper to purchase and install.


  • Higher Running Costs: The convenience comes at a price, as electric systems can be expensive to run, especially if you’re using hot water during peak electricity hours.
  • Less Energy Efficient: Compared to other types, electric systems are less energy efficient, which could impact your carbon footprint.

Ideal For

  • Smaller households where the demand for hot water is lower.
  • Those who are looking for a less expensive upfront investment.

Gas Hot Water Systems in Perth


Gas hot water systems use natural gas to heat water on demand, meaning you don’t need a storage tank.


  • Energy Efficiency: Gas systems are generally more energy-efficient than electric ones.
  • Instant Heating: Provides hot water almost immediately, which can be a significant advantage.


  • Natural Gas Connection Required: You’ll need a natural gas connection, which can be a limiting factor for some households.
  • Higher Upfront Cost: Generally more expensive to purchase and install than electric systems.

Ideal For

  • Larger households with higher hot water needs.
  • Those who prioritise energy efficiency and long-term savings.

  • Eco-Friendly: A sustainable option that reduces your carbon footprint.
  • Cost-Effective in the Long Run: After the initial investment, running costs are minimal.


  • High Upfront Cost: The initial cost of purchasing and installing solar panels can be high.
  • Weather Dependent: Efficiency can be affected on cloudy or rainy days, although backup options are available.

  • Those willing to make a higher initial investment for long-term savings.

Heat Pump Systems in Perth


Heat pump systems are a modern, energy-efficient option that uses ambient heat from the surrounding air to heat water.


  • Highly Energy Efficient: Among the most energy-efficient options available.
  • Reduced Electricity Use: Because they use ambient heat, electricity consumption is lower.


  • Higher Upfront Cost: Generally more expensive to purchase and install.
