No one enjoys having a cold shower during the winter. If you need reliable installation or servicing, Gas chill can ensure your hot water system work reliably with a consistent stream of hot water and more importantly, safely.
There are very few household inconveniences quite as jarring as turning on the shower and realising the hot water is gone. Whether your existing system has packed it in unexpectedly or you’re planning for a replacement, getting the right gas hot water system installed properly in your Melbourne home makes all the difference to how reliably it performs over the years that follow. At Gaschill, hot water system installation and servicing is something our licensed technicians handle every day across Melbourne’s inner suburbs, the southeast and the Mornington Peninsula and we bring the same care to a hot water job as we do to any of our other services.
Walk down most streets in Melbourne’s established suburbs and you’ll find a gas hot water system out the back of many homes and there are good reasons that’s been the case for decades. A gas hot water system heats water quickly and continuously, which means there’s no waiting around for a storage tank to warm up before you can run a bath or get the dishes done. For families with a few people moving through the bathroom in the mornings, that responsiveness matters more than most people realise until they switch to something slower.
Gas hot water in Melbourne also tends to have a lower cost per litre of hot water heated compared to standard electric resistance systems, which is why households with higher daily hot water demand generally find gas makes more financial sense over the life of the unit. The upfront cost of a quality gas system is a bit higher than a basic electric storage unit, but the ongoing running costs typically offset that difference within a reasonable number of years, particularly in a city like Melbourne where hot water usage peaks noticeably through the colder months.
The first decision most Melbourne homeowners face when looking at a gas hot water system is whether to go with a storage unit or a continuous flow system and the right answer depends on how your household uses hot water day to day.
A gas storage system keeps a tank of water heated and ready to always go, drawing on that reserve whenever a tap is opened. They’re straightforward, reliable and well suited to households where hot water demand is predictable and doesn’t tend to come in multiple simultaneous bursts. The trade-off is that if the stored volume runs out during a heavy-use period, you’ll need to wait for the tank to reheat and some energy is always being used to keep the stored water warm even when nobody is home. Tank sizes for residential gas systems in Melbourne typically range from around 90 litres up to 315 litres or more, so matching the tank capacity to your household size is an important part of getting the installation right.
A continuous flow system, sometimes called an instantaneous or on-demand system, heats water only when a tap is turned on, with no storage tank involved at all. Cold water passes through a heat exchanger where a gas burner fires up and brings it to temperature before it reaches the tap. The practical advantage is that you can’t run out because there’s no stored volume to exhaust and you’re not paying to keep water hot when the house is empty. These systems suit larger households well and they’re also a popular choice for Melbourne homes where outdoor space for a tank is limited. The main consideration is that the flow rate at which hot water can be delivered has limits, so it’s worth talking through your peak usage scenarios before choosing a unit and size.
Choosing a gas hot water system for your Melbourne home isn’t just about picking a brand from a list. There are a few practical factors that shape which unit will serve you well.
The first is household size and demand. A family of five with two bathrooms running simultaneously needs something quite different from a single person in a two-bedroom apartment and getting the sizing right avoids the frustration of running short during morning routines or paying more to heat more water than you ever use.
The second is the location of the installation. In most Melbourne homes, gas hot water systems are installed outdoors, which means the unit will be exposed to whatever the weather brings. Units with quality components and corrosion-resistant construction tend to perform better over time, particularly in bayside areas where salt air accelerates wear on lower-grade hardware.
The third factor is energy star ratings. Gas hot water systems are rated for energy efficiency and a higher-rated unit will cost less to run over time even if the purchase price is marginally higher. For households running a system twelve months a year, those efficiency differences add up in a meaningful way across the life of the unit.
Finally, there’s installation quality itself. A gas hot water system that is correctly sized, properly connected and compliant with Australian standards will operate more safely and reliably than one that’s been rushed or installed without due care. This is one area where cutting corners genuinely has consequences, which is why using a licensed and experienced installer matters.
With Melbourne’s ongoing shift toward electrification, the comparison between gas hot water and heat pump hot water systems comes up more often than it used to and it’s a fair question to consider. A heat pump hot water system works similarly to a reverse cycle air conditioner in that it extracts heat from the surrounding air rather than generating it directly from a fuel source, which makes it very efficient electrically. Where heat pump systems shine particularly brightly is for households with rooftop solar, because running the system during daylight hours can bring the effective cost of heating water down considerably.
Gas hot water remains the stronger option for households without solar, those in areas where gas supply is reliable and electricity tariffs are high, or situations where the hot water demand is significant enough that the immediate performance of a continuous flow gas system is genuinely preferable. Gaschill installs both and we’re happy to walk you through the comparison honestly based on your property and usage rather than pointing you toward whichever product carries a higher margin. If you’re also interested in government rebates that may apply to certain hot water upgrades, you can find current details on our heat pump hot water rebates page.

Gas hot water systems are extremely popular for being affordable and effective. They cost a bit more upfront but have lower running costs and save you money in the long run. They’re also fast, so that you have instant access to hot water when you want it without having to wait for the water to heat up.
Electric water systems cost less upfront compared to gas. They are effective and will heat your water well but there is a waiting time involved. It’s not as popular as the gas option, but there are many households that still use electric water heating systems.
Our technicians are trained professionals and can assist you with everything from air conditioning installations to servicing and repair work. If you choose Gas Chill, be rest assured that you will get:
Most residential gas hot water installations are completed within a few hours, though this can vary depending on whether pipework needs to be modified, the accessibility of the installation location, or whether additional gas fitting work is required at the meter. We’ll give you a realistic expectation of timeframe when you book.
As a rough guide, a household of two to three people typically suits a continuous flow system with a flow rate of around 16 to 20 litres per minute, or a storage system in the 130 to 160 litre range. Larger households of four or more generally benefit from a higher-output continuous flow unit or a larger storage tank. The most reliable way to get this right is to have one of our team assess your property and talk through your usage patterns.
Most manufacturers recommend a service every two to three years for standard residential use, though systems that are working harder or operating in coastal environments with higher salt exposure may benefit from more frequent checks. Regular servicing extends the life of the unit and gives you early warning of any components that are wearing or approaching failure.
Yes and it’s a conversion we carry out regularly in Melbourne homes. The main requirement is that a natural gas supply is available at the property, which is the case for many established Melbourne suburbs. If your property doesn’t currently have a gas connection, we can advise on what would be involved in getting one established.

They recently installed a heat pump water heater for me and I couldn’t be happier with the experience. I spent time researching both price and model, and this company offered the best option. After finalizing my rebate application, they were able to replace my old water heater within just two days, which was much faster than what I had read in reviews about other companies where customers waited much longer. The installation was smooth, the workmanship was excellent, and the team was friendly and professional throughout the process. Highly recommended!

The team at Gaschill are amazing to work with! From my initial enquiry with Tee about air conditioning, he provided excellent customer service explaining what would best suit our needs and responding promptly to all our emails.
Liam, Jack, and Brandon did an incredible job installing our multihead split system a few days ago. They arrived on time, were polite, thorough, and worked efficiently. They even cleaned up all the mess after finishing the job! You can really see how experienced and dedicated they are in what they do.
I would highly recommend Gaschill to anyone looking to install a split system for heating or cooling. Fantastic service from start to finish, thank you guys! My dad is a very happy man!

Gaschill did a great job of fitting 3 split systems to my property in a very timely fashion. I was impressed by their good-natured professionalism. Luke and the lads knew what was needed but also had an ear to my thoughts and adjusted where they could. Great work. I am now ready for summer.

Luke’s team recently installed a new Braemar ducted heater for us. After being quoted double the price from other companies and receiving rough service finding Luke has been a dream. I would highly recommend these guys. The communication, time management and customer service has been outstanding.
It’s nice to see a tradie care about their customers.
