Choosing a new hot water system is an important decision that can affect your comfort, energy costs, and household efficiency for years to come.
With several options available, many homeowners struggle to determine which system best suits their needs.
This guide explains the differences between gas, electric, and continuous flow systems so you can make an informed decision.
Types of Hot Water Systems
The most common systems include:
- Electric storage systems
- Gas storage systems
- Continuous flow systems
- Heat pump systems
Each offers unique advantages depending on household size and usage.
Electric Hot Water Systems
Electric systems remain one of Australia’s most common hot water solutions.
Advantages
