Types of Hot Water Systems
There are several types of hot water systems commonly used in Australian homes. The best option for your household will depend on factors such as energy availability, household size, budget and efficiency preferences.
Below is a guide to the most common hot water systems and their advantages and disadvantages.
Electric Hot Water Systems
Electric hot water systems are one of the most common systems used in Australian homes. They typically use an electric element to heat water stored in a tank.
Pros
- Lower upfront purchase cost
- Simple installation
- Suitable for most homes
Cons
- Higher running costs compared with gas or heat pump systems
- Water may take longer to reheat after heavy use
Electric systems are often the most affordable option to install, but they can be more expensive to operate depending on electricity tariffs.
Gas Hot Water Systems
Gas hot water systems use natural gas or LPG to heat water and are available in both storage tank and instantaneous (continuous flow) models.
Pros
- Faster water heating compared with electric systems
- Lower running costs where natural gas is available
- Continuous flow systems provide hot water on demand
Cons
- Requires a gas connection
- Installation costs may be higher than electric systems
Gas systems remain a popular choice in many Australian homes due to their reliability and strong performance for larger households.
Heat Pump Hot Water Systems
Heat pump systems are becoming increasingly popular due to their energy efficiency. Rather than generating heat directly, they extract heat from the surrounding air to warm the water.
Pros
- Highly energy efficient
- Lower energy bills over time
- Eligible for government rebates in many cases
Cons
- Higher upfront installation cost
- Typically installed outdoors
- May produce some compressor noise
Heat pumps can use up to 75% less electricity than traditional electric hot water systems, making them one of the most efficient options available.
Solar Hot Water Systems
Solar hot water systems use energy from the sun to heat water, often supported by an electric or gas booster for periods of low sunlight.
Pros
- Very low running costs
- Environmentally friendly
- Can significantly reduce energy bills
Cons
- Higher installation cost
- Performance depends on sunlight availability
- Roof space required for panels or collectors
Solar systems can dramatically reduce household energy consumption when installed correctly and sized appropriately.
Continuous Flow (Instantaneous) Systems
Continuous flow systems heat water only when it is needed rather than storing hot water in a tank.
Pros
- Unlimited hot water supply
- Energy efficient because water is heated on demand
- Compact size and wall-mounted installation
Cons
- Higher purchase cost
- May require upgrades to gas or electrical supply
- Flow rate must be matched to household demand
Choosing the Right Hot Water System
Hot water heating can account for 15–30% of energy use in an average household, making system choice an important decision for long-term running costs.
When selecting a new hot water system, factors to consider include:
- Number of people in the household
- Peak hot water usage times
- Energy availability (gas, electricity or solar)
- Budget and installation costs
- Long-term energy efficiency
Our experienced plumbers can assess your household’s needs and recommend the most suitable hot water system.
Hot Water System Repairs
Many hot water problems can be repaired without replacing the entire unit.
Common hot water issues include:
- No hot water
- Water not heating properly
- Leaking hot water tanks
- Inconsistent water temperatures
- Strange noises from the system
Our plumbers can inspect your system and advise whether a repair or replacement is the best option.
