How do gas hot water systems work?

Gas hot water systems use natural gas to heat water for residential or commercial use. For example, having a warm showing or running a dishwasher. Like electric hot water systems, there are two main types of gas hot water heaters, these are continuous flow hot water systems and storage tank hot water systems.

Storage tank gas hot water systems

Storage tank gas hot water systems are a reliable and widely used solution for meeting hot water demands. These systems feature a tank where water is heated by a gas burner at the tank’s base, ensuring a constant supply of hot water ready for immediate use. Once the stored hot water is depleted, you’ll need to wait until the system reheats a new batch. They offer a cost-effective and energy-efficient solution for meeting diverse water heating needs.

Continuous flow gas hot water systems

Continuous flow, or tankless, gas hot water systems provide an on-demand and efficient solution for residential and commercial applications. Unlike storage tank systems, continuous flow systems do not store pre-heated water; instead, they heat water instantaneously as it flows through the unit. This design eliminates the risk of running out of hot water, offering an uninterrupted supply as long as demand remains within the unit’s capacity. With their space-saving design and energy efficiency, continuous flow gas hot water systems are ideal for applications where a consistent and limitless hot water supply is essential, such as busy households or commercial establishments with varying usage patterns.

At Swan’s Profession Plumbing, we work with all gas hot water systems. Whether you have an existing water heater that needs replacing or have a system that is in need of a repair, don’t hesitate to reach out to our expert team of plumbers.

Why choose a gas hot water system

Fast heating

Gas hot water systems typically heat water faster than electric systems, providing hot water on demand. This is especially beneficial for households with high hot water usage or during peak demand times.


Gas hot water systems are known for their reliability and consistent performance. They are less prone to power outages and can provide hot water even during electricity outages, ensuring a continuous supply of hot water for your household.

Long lifespan

Gas hot water systems typically have a long lifespan. With proper maintenance, they can last for many years, providing reliable hot water for your household while offering a good return on investment over time.

Low operating Costs

Gas hot water systems generally have lower operating costs compared to electric models. This is especially true in areas where natural gas prices are relatively low, providing additional savings over the system’s lifespan.

Are gas hot water systems the right choice for me?

There are various factors to consider when determining whether a gas hot water system is right for you! Here are some considerations:

Large families

Homes with multiple bathrooms and a high demand for hot water benefit from the fast heating capabilities of gas systems, ensuring there’s enough hot water for everyone’s needs.

Homes with gas connections

Homes that are already connected to natural gas or are situated on a natural gas line will have a much smoother installation experience.

Values energy efficiency

If you value energy efficiency and are willing to invest in the higher installation costs, a gas system may be perfect for you. Gas is often a more cost-effective energy source compared to electricity, leading to lower energy bills over time.

Homes with space

When installing a gas hot water system, it’s important to ensure that there is enough space in your backyard for proper ventilation. Gas hot water systems require adequate airflow to safely expel combustion gases, so having sufficient outdoor space is essential.

Gas Hot Water System FAQs

Gas hot water systems are generally regarded as energy-efficient due to several factors. The use of natural gas is often more cost-effective than electricity, resulting in lower operational costs. Continuous flow gas hot water systems, in particular, offer energy savings by heating water on-demand, eliminating standby heat loss associated with traditional storage tank systems. The rapid heating capability of tankless systems ensures a constant supply of hot water without the need for preheating large volumes in advance, contributing to efficiency.

Additionally, gas burners in these systems can achieve high thermal efficiency, converting a significant portion of the fuel energy into heat. However, with all hot water systems, energy efficiency may vary based on factors like unit size, insulation, and installation. Ultimately, the most energy-efficient system is the system that best suits you and your family’s hot water usage patterns and lifestyle.

In a storage tank gas hot water system, a gas burner at the tank's base heats water stored in a tank, maintaining a constant supply; whereas, a tankless or continuous flow gas hot water system heats water on demand using a gas burner activated by a flow sensor, providing hot water instantaneously without the need for a storage tank. Both systems rely on natural gas for heating, with the storage tank type storing pre-heated water and the tankless type eliminating standby heat loss, offering options based on factors such as energy efficiency, space considerations, and hot water demand.

If your gas hot water system isn't turning on, there are several steps you can take to troubleshoot the issue:

Check the gas supply: Ensure that the gas supply to the hot water system is turned on. If the gas supply is interrupted or there's a gas outage, the system won't function.

  • Pilot light inspection: If you have a storage tank system, check the pilot light. If it's out, follow the manufacturer's instructions to relight it. If you're unsure or uncomfortable doing this, it's best to contact a professional plumber.
  • Pressure relief valve: Check the pressure relief valve on the hot water system. If it's leaking or discharging water, it may indicate an issue with excessive pressure or temperature. In such cases, it's recommended to consult with a professional plumber.
  • Check for error codes: If your hot water system has a digital display or error code system, check for any error messages. Refer to the user manual for guidance on resolving specific error codes.
  • Maintenance and cleaning: Ensure that the system is free from dirt, debris, or any obstructions. Regular maintenance, including cleaning components like burners and vents, can help prevent issues.
  • Professional inspection: If the above steps don't resolve the issue, it's advisable to contact a licensed gas technician or plumber for a professional inspection. Gas appliances involve potential safety risks, so it's crucial to have a trained professional assess and address any problems.

The lifespan of a gas hot water system can vary depending on factors such as the type of system, its maintenance, and the water quality in the area. On average, a well-maintained gas hot water system can last between 10 to 15 years.

Yes, gas hot water systems do require regular servicing to maintain their efficient and safe operation. Routine maintenance performed by a qualified gas plumber is crucial for addressing potential issues, preventing breakdowns, and optimising the overall performance of the system. During servicing, technicians typically check for gas leaks to ensure the safety of the appliance and its surroundings. Regular servicing not only extends the lifespan of the gas hot water system but also contributes to safety by identifying and addressing potential issues early on. Following the manufacturer's guidelines and scheduling professional maintenance at least once a year is recommended. If you can’t remember the last time your system had a service, it’s probably time!

Turning on a gas hot water system involves a few steps, and the specific procedure can vary depending on the type and model of the system. Here's a general guide for turning on a gas hot water system:

Locate the gas supply

Ensure that the gas supply to the hot water system is turned on. This is typically a valve located on the gas line leading to the appliance. If the gas supply was turned off for any reason, consult the user manual or contact a professional if you are unsure about how to safely turn it back on.

For storage tank systems

If you have a storage tank system, check to see if it has a pilot light. If the pilot light is out, follow the manufacturer's instructions to relight it. This process may involve turning the gas control knob to the pilot position, pressing and holding it down while igniting the pilot light, and then turning the knob to the on position.

For tankless systems

Tankless systems typically do not have a pilot light. To turn on a tankless gas hot water system, you usually need to set the desired temperature on the control panel or digital display. Once set, the system will activate when a hot water tap is opened.

Wait for ignition

After turning on the system, wait for it to ignite. This may take a few moments as the gas burner heats up the water or, in the case of tankless systems, begins heating water on demand.

Check for hot water

Once the system has ignited, open a hot water tap to check if hot water is flowing. This helps ensure that the system is working properly and that hot water is reaching the taps.
Always refer to the manufacturer's instructions or user manual for your specific gas hot water system, as the process may vary. If you are unsure about any steps or encounter difficulties, it's recommended to consult a plumber instead of attempting it yourself.
