The gas plumbing innovation is gaining grounds and here is a brief overview of the systems.

Today, many Australian households and commercial entities are embracing Gas Hot Water Technology. The reason is that many of them use hot water in their day to day operations. The technology is seen as an energy-efficient method and convenient for domestic and commercial functions.

Types of Gas Hot Water Systems

a) Gas Hot Water Storage Tank Systems

These are found in a number of sizes ranging from 90l to 170l. They are used for both domestic and commercial purposes. The tanks have the following characteristics:

• Cheap to install and run

• Delivers roughly 390l an hour

• Maintain heated water at 60°C and above

b) Gas Hot Water Instantaneous Systems

These Hot Water Systems ensure a continuous flow of hot water. They have the following characteristics:

• Hot water is delivered at a lower pressure than the storage tank systems

• Can deliver hot water to a single tap at a go

• The flow rate ranges between 10lit/min and 16lit/min

• Cheaper running cost

• Uses Natural Gas and Liquid Petroleum Gas

c) Gas Hot Water Continuous Flow System

These are similar to gas instantaneous systems. The only difference is that they are powered by electricity and gas. They also offer larger hot water flow rates, and are convenient for larger household and commercial installations. They have the following characteristics:

• The flow rate ranges between 12lit/min and 32lit/min

• Can allow multiple unit installations

• Continuous delivery of hot water

• Fairly high hot water pressure

• Flexible for both external and internal applications

• The system is powered by electronic ignition and there is no need to call a gas plumbing expert to engage a standing pilot.

d) Gas Hot Water Solar Systems

These systems use solar energy as opposed to electricity and gas. They have the following properties:

• They are the most energy-efficient systems.

• Saves 50% to 90% of hot water.

• Hot water is continuously produced.

• Give you small volumes of greenhouse emissions.

• The flow rate is between 18lit/min and 32lit/min.

Safety Practices for Home Owners

When you install the Gas Hot water System, you will need to take a few precautions such as:

• Procure a Carbon Monoxide sensor to detect when carbon dioxide is produced.

• You need to ensure that your home is well ventilated to avoid accumulation of hazardous gas.

• Due to potential gas leaks, you need to check all sources of ignition such as the fireplace, stove, and chimney.

• Be aware of hazardous signs by checking your gas appliances regularly.

When to Seek Professional Help

You can consult a trained and certified gas plumbing expert under the following circumstances:

• When installing a new Gas Hot Water System.

• When repairing an existing system.

• A land or property owner should have the system checked annually upon which a compliance certificate is issued.


Gas Hot Water Technology is getting acceptance in many Australian homes mainly because of the various market options available. The existence of gas, electricity, and solar-enabled systems offers you an opportunity to select what suits you.
