Types of Hot Water Systems


There are several types of hot water systems available in Australia, each with its own pros and cons. The best choice for you will depend on your household size, water usage, budget and access to energy sources.


1. Electric Hot Water Systems
Electric systems are common and relatively inexpensive to install. They can be storage systems – where water is heated and stored in a tank – or instantaneous (also known as continuous flow), which heats water on demand. While electric storage units can be less energy-efficient, off-peak models can help reduce energy costs.


2. Gas Hot Water Systems
Gas systems are a popular choice for households with access to natural gas. They’re generally more energy-efficient than electric systems and provide quick heat-up times. Like electric systems, they come in both storage and instantaneous models.


3. Solar Hot Water Systems
With energy prices on the rise, solar systems are gaining traction. Using rooftop solar panels to harness the sun’s energy, these systems can significantly reduce your electricity bills and carbon footprint. They typically come with a gas or electric booster for overcast days or periods of high demand.


4. Heat Pump Hot Water Systems
Heat pumps use electricity to move heat from the air into the water, rather than generating heat directly. They’re very energy-efficient and suitable for areas that don't get freezing cold – though some newer models perform well in cooler climates too, making them a viable option in the Southern Highlands.

Choosing the Right System


When selecting a hot water system, consider the following factors:


  • Household Size and Usage: A family of five will need a very different system than a couple or single person. It’s important to consider peak usage times and overall water consumption.
  • Energy Source: Depending on what’s available at your property – electricity, natural gas or solar – your options may be more limited.
  • Initial and Ongoing Costs: Installation costs can vary widely. While solar systems have a higher upfront cost, they offer long-term savings. Don’t forget to consider maintenance costs and potential rebates.
  • Environmental Impact: Many homeowners in the Southern Highlands are becoming more conscious of their environmental footprint. Solar and heat pump systems are more eco-friendly than traditional electric or gas models.

Signs Your Hot Water System Needs Attention


Not sure whether your system is working as well as it should? Look out for these signs:


  • Inconsistent Water Temperature: Fluctuating temperatures could mean a faulty thermostat or sediment build-up.
  • Strange Noises: Rumbling, popping or banging sounds often indicate sediment at the bottom of the tank.
  • Water Discolouration: Rust-coloured water can be a sign of corrosion inside the tank.
  • Leaks: Even small leaks should be taken seriously, as they can lead to bigger problems down the track.
  • Increased Energy Bills: A system that's working inefficiently will often use more energy than usual.


If you notice any of these symptoms, it’s best to call a professional who specialises in hot water systems in the Southern Highlands to inspect and repair the unit.

Frequently Asked Questions

  • What are the most common types of hot water systems available?

    Property owners can choose from several types of hot water systems depending on their energy source, household size, and preferences. The most common options include electric hot water systems, gas units, and solar-powered systems. Electric storage systems are widely used for their simplicity and affordability, while gas systems are often favoured for their efficiency and fast recovery rates. Solar systems are ideal for reducing long-term energy costs and are supported by the region’s climate, especially when paired with a gas or electric booster. A licensed plumber in the Southern Highlands can assess your needs and recommend the most suitable system for your household.

  • How long should a hot water system last before needing replacement?

    The lifespan of a hot water system can vary depending on the type of unit, its usage, and how well it has been maintained over time. On average, electric and gas storage systems tend to last between 8 to 12 years, while gas systems can last 15 to 20 years with proper care. Solar hot water systems may also last 10 to 20 years but may require occasional maintenance of the panels or boosters. Regular servicing by a qualified plumber in the Southern Highlands can help extend the life of your system and reduce the likelihood of unexpected breakdowns. If your system is ageing or struggling to meet demand, it may be time to explore replacement options.

  • What are the signs that my hot water system needs repair or replacement?

    There are several warning signs that your hot water system may need professional attention. Common issues include inconsistent water temperature, a noticeable reduction in hot water supply, unusual noises coming from the tank or unit, or rust-coloured water coming from the taps. Leaking around the tank, increased energy bills and frequent resetting of the system can also indicate a problem. It’s important to act quickly if you notice these symptoms, as delaying repairs can result in more costly damage or complete system failure. If you're experiencing issues with hot water in the Southern Highlands, contact us today.

  • Are there energy-efficient hot water options suitable for the Southern Highlands climate?

    Yes, there are several energy-efficient hot water systems that perform well in the Southern Highlands climate. Solar hot water systems are an excellent choice for energy savings and sustainability, especially with the region’s moderate sunlight levels. These systems often come with gas or electric boosters to ensure reliable performance on cloudy days. Gas systems are also known for their energy efficiency, as they only heat water when needed, reducing standby energy loss. A knowledgeable plumber in the Southern Highlands can help you compare the long-term running costs and efficiency ratings of various systems to choose one that aligns with your household’s energy goals.

  • How do I choose the right size hot water system for my home?

    Choosing the right hot water system size depends on several factors, including the number of people in your household, your daily water usage patterns, and whether you prefer storage or instantaneous systems. For example, a household of four may need a 250–315 litre storage tank or a 24–26 litre per minute continuous flow unit. If multiple showers or appliances are often used at the same time, a larger system or one with faster recovery may be more appropriate. Energy source availability—whether gas, electricity, or solar—is also a factor. A qualified plumber in the Southern Highlands can assess your home’s layout and water usage habits to recommend a system that ensures reliable hot water without excessive energy consumption or system strain.

  • Can I switch from an electric to a gas hot water system in the Southern Highlands?

    Yes, it is often possible to switch from an electric to a gas hot water system. Gas systems can offer quicker heat recovery times and lower operating costs compared to electric systems. However, the switch may require plumbing and gas fitting adjustments, including the installation of gas lines or flue ventilation. It’s also important to consider the positioning of the new unit and compliance with local building codes. Engaging a licensed plumber in the Southern Highlands who is also qualified in gas fitting is essential for safely completing this type of conversion and ensuring your new system is installed to current standards.

  • What kind of maintenance does a hot water system require?

    Regular professional maintenance is important to ensure the safe and efficient operation of your hot water system. This may include checking and replacing the temperature and pressure relief (TPR) valve, inspecting for leaks or corrosion, flushing sediment build-up from the tank, and testing the anode rod to prevent rust. For gas systems, it’s useful to clear any debris from inlet filters and ensure proper ventilation. Solar systems may need occasional cleaning of the panels and checks on booster components. 

  • Is it worth upgrading to a new hot water system if my current one is still working?

    While an older hot water system may still be operational, upgrading to a newer model can offer potential benefits in energy efficiency, performance, and long-term reliability. Modern systems are often designed to meet higher energy standards, which can result in noticeable savings on utility bills—particularly if you’re switching from an older electric system to a gas or solar model. Newer units also come with improved safety features and more compact designs, offering installation flexibility. In the Southern Highlands, where heating demands can be high during cooler months, upgrading to a more efficient hot water solution may provide more consistent performance. It’s worth discussing your current system’s condition with a local plumber to assess whether a proactive upgrade would be beneficial.

  • How much does hot water system installation cost in the Southern Highlands?

    The cost of installing a hot water system in the Southern Highlands can vary depending on the type of system chosen, the complexity of the installation, and whether it's a direct replacement or a complete system change. Basic electric storage systems may have a lower upfront cost, while gas or solar systems tend to be more expensive initially but may offer long-term savings. It’s recommended to obtain a detailed quote from a licensed plumber in the Southern Highlands who can assess your home’s layout and provide a clear breakdown of the associated costs for your specific situation.
