Frequently Asked Questions

  • Why is my hot water system not producing hot water?

    A hot water system may stop producing hot water due to faulty heating elements, thermostat issues, gas supply problems, leaks or general wear and tear over time. Older systems can also become less reliable as components age. A licensed plumber can inspect the system to identify the cause and recommend repairs or replacement if needed.

  • How long does a hot water system usually last?

    Most hot water systems last between 8 and 15 years, depending on the type of system, water quality, maintenance and usage levels. Regular servicing can help extend the lifespan of the unit and improve efficiency. Signs a system may need replacing include inconsistent water temperature, leaking tanks, unusual noises or rising energy costs.

  • What size hot water system do I need?

    The right hot water system size depends on the number of people in the household, water usage habits and the type of appliances connected to the system. Larger households generally require bigger storage tanks or higher-capacity continuous flow systems to ensure reliable hot water during peak usage times.

Hot Water Systems

  • Gas Hot Water Systems: Gas hot water systems are a dependable and economical choice. They typically boast a high recovery rate, meaning they can heat a larger volume of water more quickly. These systems can operate on natural gas or LPG and newer models are incredibly energy efficient, reducing your carbon footprint and energy bills.


  • Electric Hot Water Systems: Electric hot water systems are popular due to their affordability and ease of installation. They can be either storage tank or instantaneous models. While they can be more expensive to run than gas systems, their lower upfront cost and the ability to use off-peak electricity for heating can help offset operational costs.



  • Solar Hot Water Systems: Solar hot water systems are an environmentally friendly and energy-efficient option. They use solar panels to capture sunlight and convert it into energy to heat the water. Although the initial outlay can be higher, the savings on energy bills over time and the potential for government rebates make them an attractive option.
