Benefits Of a Gas Hot Water System
Gas hot water heaters are one of the most popular hot water systems in Sydney. They provide a wide range of benefits that make them a smart investment for your home or business.
Gas hot water heaters are among the most efficient systems available. Unlike electric hot water systems, which continuously use electricity to maintain water temperature, gas hot water systems heat only when needed. This eliminates energy waste, reducing your carbon footprint while cutting costs.
Storage tank systems, though slightly less efficient in continuous heating, often have higher energy ratings and are excellent when paired with solar panels. For ultimate ability, the flow systems heat water instantly when the tap is turned on, ensuring zero heat loss in standby. This makes these systems ideal for homes that value order and savings, no matter the household size.
Homeowner Tip: Pair your gas hot water system with solar panels for a remarkable hybrid solution that provides both ecological and economic benefits, even when relying on off-peak electricity at night.
Tired of running out of hot water during morning rushes? Gas systems, particularly instantaneous hot water systems, ensure you’ll always have reliable, consistent access to hot water, even during peak usage hours.
For homes with multiple bathrooms or appliances, a gas system is unmatched. It can effortlessly handle simultaneous showers, dishwashers, and washing machines without compromising water temperature or flow. Unlike electric hot water systems, which may falter under high demand, gas systems are built to serve busy households with ease.
Real-World Example:
Imagine your family of five taking consecutive showers while the dishwasher runs, all without worrying about running out of water. A continuous gas flow system makes this possible, ensuring uninterrupted comfort.
A key advantage of gas hot water heaters is their rapid heating capability. Gas continuous systems provide near-instant hot water, heating it as it flows through the unit. This ensures you won’t have to wait, no matter the time of day.
Whether you’re hosting guests or simply getting through a busy morning, gas systems are built to meet high capacity demands. Unlike storage-based electric systems, gas water systems heat faster and maintain optimal temperature efficiently.
Ideal Scenario: Homes with frequent guests and larger households benefit immensely from the speed and capacity of gas systems, ensuring no one is left without hot water.
Potentially Lower Operating Costs
Gas systems are typically cheaper to run than electric ones, making them a cost-effective choice. Thanks to Sydney’s competitive prices, you’ll notice the reduced running costs in your bills almost immediately. A gas storage system or gas continuous flow system provides exceptional energy savings over time, making it the go-to option for budget-savvy households.

Great work by Oliver Jake and Phil. Everything works perfectly
Matthew was swift to respond and diagnose the issue with our lack of water pressure. Initial estimates indicated the need to temporarily bypass a section of piping until we could locate the blockage before performing a more permanent solution. During testing for pipe location it was determined a faulty isolation valve was the culprit negating the need for the temporary solution and significantly reducing the cost of the solution. Matthew was courteous and professional throughout and once diagnosed correctly was a swift fix, would highly recommend.
Over two days of working outside to unblock a private stormwater easement affecting four properties on the same easement, Phil and Matthew brought us success. Happy to have them anytime. Great workers. Network you certainly have the right people for the job.
Network Plumbing is excellent! Another emergency blocked loo! So close to Christmas I didn’t think the issue would be resolved and I would have cancel planned celebrations . One phone call and Tim arrived within 3 hours resolving the problem. Tim is absolute gentleman! Every person I deal with at company is so professional.

Lovely professional and friendly guys - highly recommend!
I really appreciated Jordan’s upfront approach. He was communicative, clear about the potential cost of the project, offered helpful suggestions and turned up bang on time. He was honest about the work that would be involved, to the point of recommending a completely different approach, which was very refreshing. I’ll definitely be asking for him for future plumbing work!
Outstanding service by Tampenny. Very helpful and obliging. I very happy with my service today. I highly recommend Tampenny.

Tom and Jad did a wonderful job, punctual, efficient and personable. Thanks guys! Highly recommend.
I want to thank Oliver, the plumber who came in for a complimentary check. He was very professional , courteous and did a thorough check. Thank you Oliver.
I could not recommend Network Plumbing, Electrical and Air Conditioning more highly! These people were incredible in their service, workmanship and remarkable turnaround time and everyone I dealt with was wonderful! After the first company I called to replace our broken water heater charged me to send someone to check it and then couldn’t even give me an estimate of when they could install a new one, I called Network at 2pm and had a new water heater in by 8pm. Could not be more impressed with Will, Bill and Ryan for their amazing work and professionalism! It was a great experience dealing with this company and I will definitely use them again.
Andrew , Liam and Phil were fantastic , really hard workers and did a excellent job. Highly recommended!
Good communication and response to problem
I had Jake and Sandro do two seperate jobs in quick succession and they were both excellent, speedy, clear communication, good workmanship. Would recommend
I have 4 kids and our air conditioning broke down on a really hot day — total chaos! I called Network Plumbing Services and Sally was so lovely taking my booking, super understanding and helpful. Sarkis arrived within the hour and had everything up and running so quickly. He was friendly, professional, and explained everything clearly. Couldn’t be more grateful for such fast and reliable service — highly recommend!
After a very satisfactory resolution by Network Plumbing, I wish to upgrade the rating I gave them earlier about their somewhat excessive charge. Network Plumbing acknowledged their over-estimation and met all my demands promptly, generously and with integrity. Impressive 5-star performance in this case. Thank you!
Sandro came this morning to replace a toilet. He was extremely professional and efficient. He was punctual and very courteous.
Peter responded promptly to our emergency call out and in addition to fixing the issue was very friendly and offered good advice
Fasts and reliable. Jake magic hands did a great job.
Matt, Joey & Levi did an excellent job replacing our damaged sewer pipe & leaving the dug up area in great condition. Thanks guys. Today Cameron installed our .new laundry cabinet. Looks great thanks.
I had Scott and the boys out to do a re-line. Very helpful and explained what was happening. They were all very polite and left my place clean and tidy. I would recommend them to anyone.
Team Tom and Cameron is absolutely amazing! Quickly identified the cause of blockage and cleared it up thoroughly. I really appreciated them for explaining the problem and their solution in plain words as I had no idea how the plumbings work; my 6 yo son was all ears as Tom described how they tackle the problem and now he is totally fascinated. 100% recommend Network Plumbing.
Great service. I really appreciated the thorough job and explanation of problem.
Tristan was punctual and absolutely helpful resolving the issue. Initially thought the issue is a damp motor failure. However, Tristan thoroughly tested other scenarios may be causing the issue, and diagnosed the underlying problem without having to replace any parts. Thank you Tristan for the great work and honesty. Highly recommend this business and will use them again for sure!
Excellent service and attitude. Very patient and understanding working around my 97 year old mother. On time, polite and courteous. Thank you Sandro, Reece and Rob for your work , both plumbing and electrical.

Frequently asked questions
Have more questions about your gas heater, heating system, or gas appliances? Our team has the answers and reliable solutions to keep you warm and safe.
Replacing a gas hot water system varies based on capacity, brand, installation complexity, and whether existing pipework or gas lines need modification. Rather than quoting over the phone, our Sydney technicians assess your current system, confirm what size and model fit your home best, and explain the options clearly before any work begins – so you get the most value and longevity for your investment.
Common issues include pilot light failures, burner inefficiencies, faulty thermostats, scale build-up, and pressure valve problems. These can lead to inconsistent temperatures, reduced hot water supply, or complete shutdown. Regular servicing helps catch these early, and a professional assessment will determine whether repair or replacement makes more sense.
Well-maintained gas hot water systems in Sydney typically last 10–15 years, depending on usage, water quality, and maintenance history. Systems in high-use homes or hard-water areas may see a shorter life, while regular servicing can help maximise lifespan.
For a Sydney family of four, most homes benefit from a medium to large capacity gas hot water system — typically around 160–250 litres (or the equivalent in continuous flow models). The right size depends on your showering habits, number of bathrooms, and peak demand times. Our team can assess your household needs and recommend the ideal system during an on-site visit.
Signs your gas hot water system may be failing include:
• Inconsistent hot water
• Strange noises from the tank
• Rusty or discoloured water
• Pilot light issues
• Frequent cycling or short runs
These symptoms often appear before total failure. A licensed technician can diagnose the underlying cause and recommend the best solution.
Short hot water duration can be caused by undersized systems for your household, thermostat issues, sediment build-up inside the tank, or compromised burners. Because there are multiple potential causes, it’s best to have a professional assess your system on site to pinpoint what’s limiting hot water supply.
Both types have similar lifespans, often 10-15 years – but durability depends on usage patterns, water quality, and maintenance. Gas systems heat water faster and are often more efficient for larger households, while electric models may be simpler to install but can cost more to run. A tailored assessment helps decide what’s best for your Sydney home.
If you never flush a water heater, sediment and mineral build-up accumulate inside the tank over time. This reduces efficiency, increases wear on internal components, raises energy costs, and can shorten the system’s life. Regular servicing – including flushing as required, helps keep the system performing reliably.
“Better” depends on your home’s needs:
• Gas systems typically offer faster recovery and lower running costs in high-demand households.
• Electric systems may be simpler upfront but can cost more to run.
A professional assessment considers usage, gas availability, energy costs, and your household’s daily hot water patterns to recommend the right choice.
You might consider replacement when:
• The unit is over 10–15 years old
• Frequent breakdowns occur
• Repair costs approach the value of a new system
• Efficiency drops significantly
A licensed Sydney technician can assess your system’s health and advise whether repair or replacement is the smarter long-term choice.
Before complete failure, systems often show warning signs such as:
• Reduced hot water supply
• Loud rumbling or popping noises
• Rust-coloured water
• Pilot light issues or flame irregularities
Catching these early with a professional inspection can prevent unexpected loss of hot water.
You can check for obvious signs like:
• Is the pilot light lit?
• Are there unusual noises?
• Is the water rusty or discoloured?
• Does hot water run out quickly?
However, diagnosing underlying issues or safety concerns, especially with gas systems – should be done by a licensed professional who can safely inspect combustion, pressure, and venting.
