How gas hot water systems work

Gas hot water systems use gas to heat water quickly and deliver it to the taps, showers and appliances around your property. Depending on the type of system, the water can either be heated and stored in a tank or heated as you use it. The right option for your Sydney home depends on factors such as household size, hot water demand, available space and your existing plumbing and gas connections.

Which gas hot water system is right for your Sydney home?

We look at how your household uses hot water, how many people live in the property, the number of bathrooms and outlets, available installation space and your existing gas and plumbing setup.

Gas storage for consistent hot water

A gas storage system can be a good choice for households that use hot water across several outlets throughout the day.  When recommending a storage system, we consider the tank size carefully. A tank that is too small may struggle during busy periods, while a larger system than you need can take up unnecessary space.

Continuous flow for on-demand hot water

If you prefer a compact system that heats water as you use it, a gas continuous flow system may be worth considering. There is no large storage tank, and the unit heats incoming water when a hot water tap or shower is turned on. Our plumbers can assess your existing setup and help determine if continuous flow is a suitable option for your property.

Gas-boosted solar for solar homes

Already have solar or considering a solar hot water system? A gas-boosted solar setup combines solar water heating with gas support when additional heating is needed. This can be an option for Sydney households looking to make greater use of solar energy while keeping a gas booster available for periods when solar heating isn't enough.

Professional advice before installation

Every property is different, so we don't take a one-size-fits-all approach. Our licensed plumbers can assess your current hot water system, discuss your household's needs and explain the available gas hot water options before recommending a solution.

From new installations and system upgrades to repairs and replacements, Emergency Home Services provides professional gas hot water services across Sydney. If your current system is no longer keeping up with your needs, we'll help you understand your options and find a practical solution.

FAQ Hot Water

Have More Questions?
Contact us

What types of hot water systems are there?

There are several types of hot water systems available in Sydney, including storage tank systems, instant or continuous flow systems, heat pump systems, solar hot water systems, and hybrid systems.

What are signs my hot water system needs a repair, replacement or service?

Signs that your hot water system may need repair, replacement, or servicing include water leaks, rust or corrosion, inconsistent water temperature, strange noises, or a significant increase in energy bills.

How do you service a hot water system?

We advise you to make sure you schedule hot water maintenance at least twice a year. This way a plumber can monitor and check if there's any problem and fix it right away. Our plumber here at Emergency Home Services can clean air filters, monitor pressure relief valve, check the condenser/coils and keep an eye out for leaks. Regular maintenance is the key to a long-lasting and efficient hot water system.

What is the most efficient hot water system?

Heat pump hot water system is considered to be the most efficient hot water system. It uses less energy compared to traditional electric or gas systems. Before you choose which hot water system fits your needs, make sure to consider factors such as energy source, size of the household, and usage patterns.

How do you know if your hot water system needs replacing?

Signs that indicate your hot water system may need replacing are: significant decrease in hot water temperature or pressure, frequent breakdowns or repairs, rust or corrosion on the tank, strange noises coming from the system, and an increase in energy bills despite normal usage.If you notice any of these signs, contact our plumbers for assessment.

What is the average lifespan of a hot water system?

The average lifespan of a hot water system is around 10-15 years. Tankless systems can last up to 20 years or more with proper maintenance. Emergency Home Services can help you find the right hot water system fit for your needs. We offer all shapes and sizes of hot water systems from all brands.

Do hot water systems need servicing?

Yes, hot water systems do require regular servicing to ensure they operate efficiently and safely. Routine maintenance tasks may include flushing the tank to remove sediment buildup, checking for leaks and corrosion, testing pressure relief valves, adjusting temperature settings and more. Our plumbing team in Sydney is qualified to perform hot water maintenance.

Does a leaking hot water heater need to be replaced?

If you have a water heater leaking from the bottom of your hot water heater, then it needs to be replaced. If the tank itself is severely corroded or damaged, replacement may be the best option to prevent further leaks and water damage.

What to do if your water heater is leaking from the bottom?

First, turn off the power or gas supply to the heater and shut off the water supply. Then, check the source of the leak. If it's coming from a valve or fitting, you may be able to tighten or replace it yourself. However, if the tank itself is leaking, it's best to contact a professional plumber to evaluate the situation and recommend the appropriate repairs or replacement.

What is the most economical hot water system?

Solar hot water systems tend to be among the most economical options over the long term, as they rely on free energy from the sun to heat water. If you’re after solar hot water heaters, we service and install all types.

Is it cheaper to heat water with gas or electric?

Gas water heaters are cheaper to operate than electric heaters, especially if you have access to natural gas at lower rates. However, the initial installation cost of gas systems may be higher, so it's essential to consider both upfront and ongoing expenses when comparing the two options.

What size hot water tank for a household?

A household of 2-4 people typically requires a hot water tank with a capacity of 40-60 gallons (150-225 liters).5+ people may require 50-70 gallons of water. Consult with a professional plumber to determine the right size tank for your specific needs.
