Instantaneous electric hot water systems are compact and energy efficient.
When it comes to hot water, we want a water heater that is efficient, reliable, and capable of meeting your household or business needs. Instantaneous electric hot water systems, also known as tankless water heaters, have grown in popularity due to their energy efficiency and compact design.
Note: These systems are also called continuous flow or tankless hot water systems.
Available in a range of sizes and hot water outputs, there is an instantaneous electric hot water system to suit everyone’s needs. The right size depends on your household size, water usage habits, and the number of hot water outlets.
- Small: Ideal for single sinks or low-demand setups.
- Medium: Suitable for small apartments or homes with minimal water usage.
- Large: Designed for family homes or higher water demands, capable of handling multiple taps simultaneously.
How does instantaneous electric hot water work?
Unlike traditional storage water heaters, instantaneous systems heat water only when it’s needed making them an energy-efficient and cost-effective option for many households and businesses.
- Water flow activation: When you turn on a hot water tap, cold water flows through the unit.
- The heating element is engaged: The system’s powerful electric heating elements activate and heat the water as it passes through.
- A continuous hot water supply: Hot water is delivered immediately, as long as the tap remains on, without relying on a storage tank. This on-demand mechanism eliminates the need for storing heated water, reducing energy usage and making these systems a highly efficient choice.
How is an instantaneous electric water heater installed?
Installing an instantaneous electric hot water system requires professional expertise to ensure safety and efficiency. Generally, the process is as follows:
- We assess your needs: We’ll evaluate your hot water requirements and recommend models that will accommodate your needs and budget.
- Electrical connection: These systems require a high-power electrical connection. Some properties may require an upgrade of their wiring or switchboard to handle the load. If required, we are licensed and qualified to undertake all the necessary work. This saves considerable time and money as we don’t have to outsource to other tradespeople.
- Mounting an instantaneous electric water heater: The compact unit is typically mounted on a wall, requiring a lot less space when compared to traditional hot water systems.
- Plumbing integration: The system is connected to your existing plumbing for seamless water flow.
- Testing and commissioning: Once installed, we’ll test the water heater to ensure it is working correctly and adheres to all safety compliance requirements.

Did you know that often the repair and installation of a hot water system requires the expertise and qualifications of both a licensed plumber and a licensed electrician?
We are qualified to undertake any plumbing and electrical work required to ensure your hot water heater is repaired quickly and within budget. Plumbers who do not specialise in the installation of hot water heaters may need to outsource the electrical work required to another tradesperson, thereby holding up your hot water system repair or installation, adding extra expense due to additional call-out fees charged by employing two tradespeople.
Your hot water heater is an expensive appliance. Don’t risk voiding your warranty.
Additionally, most manufacturers won’t cover the terms of your hot water system warranty if it isn’t installed by a licensed hot water technician or a qualified plumber. Hot water tanks are an expensive appliance so why would you risk voiding your warranty by installing it yourself or employing the services of someone who isn’t licensed?
