Gas hot water systems are a popular option for homes that have access to a suitable gas supply. They use gas to heat water and are available in different configurations to suit household size, hot water demand and installation requirements.
At Illawarra Hot Water, we can help you compare gas hot water systems, capacities and configurations to find an option suited to your home.
Gas hot water systems use gas to generate heat, which is transferred to water for household use. The exact process depends on whether the system stores heated water or heats water as it is needed.
Gas storage systems heat water and store it in an insulated tank until it is required.
The available storage capacity can be selected according to household size and expected hot water demand. This type of system can be suitable for homes that prefer having a stored supply of hot water available for household use.
Best suited to:
Homes that require stored hot water and have sufficient space for a storage tank.
Key consideration:
Tank capacity should be matched to household demand and peak usage.
Gas continuous-flow systems heat water as it passes through the unit rather than storing a large volume of heated water.
When a hot water outlet is opened, the system activates and heats the water as it flows through the heat exchanger. The required system size depends on the expected flow rate and household demand.
Best suited to:
Homes looking for a compact, on-demand hot water configuration where the available gas supply and installation requirements are suitable.
Key consideration:
The system needs to be correctly sized according to flow rate and simultaneous hot water usage.
Gas systems use gas as their energy source for heating water, providing an alternative to electric hot water systems.
Choose between a storage system that keeps heated water in a tank or a continuous-flow system that heats water as it passes through the unit.
Gas storage systems are available in different tank capacities, while continuous-flow systems are available with different flow-rate capabilities.
Gas systems can be selected according to household size, hot water demand, property layout and existing infrastructure.
Continuous-flow systems do not require a large hot water storage tank, which can make them an option where installation space is limited.
A range of manufacturers and models allows you to compare features, capacities and configurations when choosing a new gas hot water system.
Gas can be a suitable hot water option for homes with access to an appropriate gas supply, but the right system depends on your property’s infrastructure and household requirements.
Your property needs access to a suitable gas supply for the selected system. This may include natural gas or LPG, depending on the property and product.
Consider how many people live in your home, how many bathrooms you use and whether multiple hot water outlets are likely to operate at the same time.
Gas storage and continuous-flow systems operate differently. Storage systems provide a tank of heated water, while continuous-flow systems heat water as it is required.
Consider where the system will be installed and whether there is sufficient space for the selected unit, along with the required plumbing, gas and other connections.
If you’re replacing an existing hot water system, the current gas supply, plumbing, installation location and system configuration should be assessed before choosing a replacement.
Gas hot water system sizing is not based on household size alone. The appropriate system depends on how much hot water your household uses, when it is used and whether multiple outlets are likely to operate at the same time.
For storage systems, important factors include:
A larger household may require a larger storage capacity, particularly where several people use hot water around the same time.
Continuous-flow systems are generally selected according to required water flow rather than tank capacity.
Important considerations include:
An appropriately sized system can help ensure that your hot water system is capable of meeting normal household demand.
For this reason, it’s better to assess your actual usage and property requirements rather than selecting a system based on household size alone.
A gas hot water system uses gas to generate heat for heating water. Gas storage systems heat and store water in a tank, while continuous-flow systems heat water as it passes through the unit.
Gas storage systems heat water and keep it in an insulated tank until it is needed. Continuous-flow systems heat water as it passes through the unit, without relying on a large storage tank.
The right size depends on your household’s hot water demand, number of bathrooms, number of simultaneous outlets and, for continuous-flow systems, required water flow. A hot water specialist can help determine an appropriate size for your property.
A gas system may be an option for some properties, but suitability depends on the availability of an appropriate gas supply, installation requirements and the selected system.
Gas hot water systems require a suitable gas supply. Depending on the property and system, this may be natural gas or LPG.
The service life of a gas hot water system depends on the model, installation, water quality, usage and maintenance. As a system ages, ongoing repairs and its overall condition should be considered when deciding whether replacement is appropriate.
A lack of hot water or inconsistent water temperature can have several possible causes. Gas supply, system components, water flow and other factors can affect performance. A qualified technician should assess the system to determine the cause.
Different homes have different hot water requirements. The right system depends on factors such as household size, daily hot water usage, available energy sources, installation requirements and running costs.
Electric storage systems are a familiar and practical option for many Australian homes. They are available in a range of capacities to suit different household requirements.
Gas hot water systems can provide reliable hot water and are available as both storage and continuous flow systems.
Solar hot water systems use energy from the sun to heat water and can help reduce reliance on conventional energy sources.
Heat pumps use heat from the surrounding air to heat water efficiently. They can be an excellent option for households looking to improve energy efficiency.
