We install all types of hot water systems for Melbourne homes
There’s no single hot water system that suits every home. That’s why Outright Plumbing installs a full range of options, so you can choose the system that fits your household, budget, and long-term needs.
Electric hot water systems for reliable supply
Electric storage tanks remain a practical choice for smaller households or properties without gas access. Our plumbers install new units safely, remove old systems, and ensure your home has steady hot water from day one.
Gas hot water systems for families and businesses
Gas hot water systems (both storage and continuous flow) are a popular option for homes that use a lot of hot water. We install gas units that deliver quick recovery, strong flow rates, and lower running costs compared to many electric systems.
Continuous flow hot water systems for on-demand hot water
Continuous flow units heat water only as you need it, so you’ll never run out mid-shower. They’re compact, energy-efficient, and perfect for households that want a modern system that saves space without sacrificing reliability.
Solar hot water systems for energy efficiency
Solar systems combine roof-mounted panels with a booster for cloudy days, giving you reliable hot water while reducing energy bills. Our team installs solar hot water units that are built for Melbourne’s conditions and long-term performance.
Our plumbers share their insights on hot water installations
Installing a new hot water system isn’t just about connecting pipes and turning it on. The choices made at installation can affect performance, running costs, and how long the unit lasts. Here are some of the key things we think every homeowner should know before getting a new system.
Correct system sizing is critical for hot water installations
One of the biggest mistakes we see is households installing systems that don’t match their needs. Oversized units heat more water than necessary, wasting energy and pushing up bills. Undersized systems run out of hot water during peak times and wear out quickly because they’re always running.
Our plumbers look at more than just household size. We factor in the number of bathrooms, how often appliances like washing machines and dishwashers run, and when your family typically uses the most hot water. Getting the size right means you’ll always have enough hot water without paying for more than you need.
Installation location affects performance and lifespan
Where a hot water unit is installed makes a bigger difference than most people realise. A system placed too far from the bathroom or kitchen wastes water and makes you wait longer for it to run hot. Poor placement can also expose tanks or pipework to the weather, leading to faster corrosion or more frequent maintenance.
Indoor vs. outdoor placement matters too. Indoor units need proper ventilation, while outdoor units should be protected from extreme weather. A well-chosen location improves efficiency, reduces heat loss, and makes the system easier to service in the future.
Water quality in Melbourne matters for new hot water systems
Not all suburbs in Melbourne have the same water quality. Some areas have higher mineral content or sediment levels that can build up inside tanks and fittings. This speeds up corrosion, reduces efficiency, and shortens the system’s lifespan.
We often recommend protective measures like sacrificial anodes, tempering valves, or filters to suit local conditions. These small additions can add years to the life of a system and help avoid costly repairs.
Compliance and safety checks protect your home
Every hot water installation must meet strict Australian standards. Gas systems need correct fluing and ventilation, while electric systems require safe electrical connections and earthing. Temperature and pressure relief valves are installed to prevent dangerous faults.
Licensed plumbers pressure-test the system, confirm the thermostat is set to the correct temperature, and make sure safety valves are functioning before the unit is commissioned. These checks not only protect your home but also keep the manufacturer’s warranty valid. Skipping them can leave you with unsafe plumbing and no coverage if something goes wrong.

Hot water installations for commercial and managed properties
Installing hot water systems in commercial settings comes with higher stakes.

- Builders and developers: We install hot water systems for new builds and renovations, coordinating with other trades to keep projects on schedule. Our team ensures every system is compliant, pressure-tested, and ready for inspection at handover.

- Schools and community facilities: Larger properties need systems designed for high-volume use at peak times. We install storage and continuous flow systems that provide reliable hot water where it’s needed most.

We know Melbourne’s hot water systems inside out
Across Melbourne’s southern suburbs, we’ve installed and replaced every type of system: old electric tanks tucked away in Brighton garages, solar units in Sandringham homes, and continuous flow gas heaters in Cheltenham apartments. Whatever system you’re moving to, we know the quirks and the right way to set it up.
We focus on long-lasting hot water installations
Installing a new hot water unit is an investment, and we don’t cut corners. We use quality valves, fittings, and insulation that protect your system for years, not months. Our plumbers also test pressure and flow to make sure the system won’t be put under unnecessary strain.
We can take care of other plumbing while we’re on site
Hot water installation is often a good time to sort out other jobs. If you’ve got an old tap that’s dripping, a toilet that needs attention, or outdoor plumbing that’s starting to wear, we can take care of it during the same visit, so you don’t need to book a second call-out.
We keep everything clear and upfront
There’s no jargon or surprises. We’ll show you what needs doing, explain your options for different systems, and give you a fixed price before starting. That way, you know exactly what’s happening from start to finish.
We work across Melbourne’s southern suburbs
Our base is in Bayside, but we cover the lot from Caulfield East down to Mordialloc, across to Hampton and Keysborough. If you’re in range, we can usually be there the same day.

Frequently asked questions about hot water systems
From how long a system should last to whether it’s worth repairing instead of replacing, we’ve heard it all. Our FAQs cover the most common hot water supply queries so you can get clear, practical answers before we even step through the door.
How much does it cost to replace a hot water system in Melbourne?
The cost of replacing a hot water system in Melbourne can vary a lot depending on the type, size, and brand you choose. As a ballpark, you might be looking at anywhere from $1,200 to $3,500 for supply and installation. Continuous flow hot water systems are generally cheaper upfront than large storage hot water tanks, while solar and heat pump units can be more of an investment but cheaper to run long-term.
When we handle a hot water system installation, we’ll talk you through the options, explain the running costs, and give you a clear, fixed price before we start. If we spot any other plumbing issues while we’re there (like leaks that could shorten your system’s lifespan), we can also take care of them on the spot with our leak detection service.
What types of hot water systems do you repair and install?
We work on all major types of hot water heaters: electric storage, gas storage, continuous flow (instantaneous), solar, and heat pump systems. Whether your unit’s tucked away in the roof cavity, mounted outside, or sitting in the laundry, we’ve seen it all.
Our hot water system maintenance plumbers can repair faulty components, replace worn-out units, or keep things running smoothly. If you’re upgrading, we’ll make sure your new system is sized correctly for your household and installed to manufacturer standards. And because hot water problems can sometimes be linked to other plumbing issues, we can also handle related jobs like low water pressure fixes or tempering valve installation and repair.
How long does a new hot water system installation take?
In most cases, we can remove your old unit and install the new one in about 3–5 hours. If we’re switching types (for example, from gas hot water systems to an electric hot water unit) or moving the system to a different location, it can take a bit longer. We’ll let you know exactly how much time to allow when we quote the job. Our goal is to have your hot water back the same day.
What’s the average lifespan of a hot water system?
Most hot water systems last between 8 and 12 years, depending on the type, brand, and how well they’ve been maintained. Gas and electric hot water systems often start showing wear after 10 years, while continuous flow units can last longer with regular servicing.
You can extend your system’s lifespan with annual hot water system maintenance. This helps prevent sediment build-up, catches small leaks early, and ensures safety components are working properly. We can also give the rest of your plumbing a quick once-over to make sure there aren’t other issues, like leaking taps, that could waste hot water and put extra load on your system.
What brand of hot water system is most reliable?
Reliability often comes down to matching the right brand and model to your household’s needs. We’ve had good results with quality hot water brands like Rinnai, Rheem, Vulcan, and Bosch for gas and continuous flow units, and Thermann for electric systems. For solar and heat pump setups, brands like Apricus and Reclaim Energy are solid choices.
We’ll always recommend an efficient hot water system we’d happily install in our own homes. We’ll walk you through the pros, cons, and warranty terms so you can make an informed decision.
Is solar hot water worth it in Melbourne?
It can be, especially if you’ve got good roof space facing north and want to cut your energy bills. Solar hot water systems can cover most of your hot water needs in summer, with a gas or electric booster kicking in during cloudy winter stretches.
The upfront cost is higher than a standard system, but government rebates and lower running costs can make up for it over time. If you’re thinking about going solar, we can assess your home’s setup, check your roof for suitability (alongside our roof plumbing service), and give you a clear picture of the savings you can expect.
