Continuous Flow Hot Water Systems Explained by a Plumber

Innovative, effective, and more efficient hot water systems are replacing traditional storage tanks. Continuous flow hot water systems can be found in an increasing number of Australian homes. There are several options to choose from.

Installing a new hot water system or upgrading from an old one is an investment. To ensure that homeowners get value for their money, they should choose brands that are trusted in the field and consult a plumber to make sure they’re making the right decision for their home and needs.

What are Instantaneous Flow Systems?

As the name suggests, these are hot water systems that instantly supply hot water as soon as the taps are turned on. Whether you choose to use gas, electric, or solar models, the hot water functionality remains the same. Since the water is only heated at the moment when it is needed, these systems are more efficient and cost-effective than traditional storage-based water heaters.

With so many options in the market for hot water systems, it's easy to get overwhelmed and confused. Before purchasing a system, there are some considerations buyers should think about to help them make a good choice. One thing to look out for is the Energy Rating Label. This can help you to determine how efficient your new system is going to be.

Types of Tankless Water Heating Systems

The models for these systems include electrical, gas, and solar designs.

Gas fueled continuous water heating systems require a connection to an existing natural gas supply line. A burner is ignited when hot water is needed in the home. Sometimes, homeowners will need to modify their homes to accommodate a gas-powered system.

Electric tankless systems are the most popular option. They use an electric element that is coiled around the pipes inside the unit to rapidly heat the water as it moves through. They are cheaper to install upfront than gas systems, and they usually take up less space.

Solar options harness the sun’s power using panels on the roof of a home. They can have high initial costs and usually are used in combination with gas and electric options.

Positives of Continuous Systems

The benefits of using these systems are:

  • * They are fuel-efficient

  • * They are cost-effective, helping you save money since they use less energy

  • * Saves space inside the home

The drawbacks to these systems include:

  • * When the power goes out, the hot water goes too. They may not be the best choice in areas where there are frequent power outages.

  • * If you are running many hot water gadgets in your home, water pressure or temperature may be inconsistent.


No one wants to live in a house without reliable hot water. Whether you are planning to install new hot water systems or upgrading, it's important to consider the quality and model of the product, and to hire a licensed plumber to install the system. A good plumber can help you decide which types of hot water systems are best for you.
