Cold showers. Dishes piling up. A system that’s leaking, making strange noises, or just stopped without warning. When your hot water goes out, it affects everything. You need it sorted fast, by someone who knows what they’re doing.
We’re SOS Plumbing and Gas, a small, local team based in Seaton, and hot water repairs are a big part of what we do every day. We work on gas, electric, solar, heat pump, continuous flow and gravity fed systems, across all major brands. With same-day service and our 1-Hour Arrival Guarantee, you won’t be waiting long.
Signs your hot water system needs repairs
Don’t wait until the system fails completely. Watch for these warning signs:
- No hot water, or water that goes cold quickly in the shower
- Water leaking from the base of the tank or around the fittings
- Water running constantly from the relief valve, rather than the occasional drip while it heats
- Hissing, rumbling, popping or knocking sounds from the unit
- Rusty or discoloured water from the hot taps only
- Lower pressure on the hot tap than the cold
- A pilot light that keeps going out on a gas system
- Energy bills climbing with no change in how you use hot water
- A system over 10 years old that keeps needing attention
Any of these means your system needs a professional look. The sooner you call, the cheaper the fix is likely to be.
Smell gas near your hot water system? Turn off the gas at the meter, don’t use switches or naked flames, open doors and windows, and call us or your gas emergency line straight away.
Hot water repairs for all system types in Adelaide
Gas hot water repairs Adelaide
Gas storage and gas continuous flow systems are found in homes right across Adelaide. Pilot light faults, thermostat failures, gas valve issues and ignition problems all need a licensed gas fitter. We repair both gas storage tanks and gas continuous flow systems across the whole metro area.
Electric hot water repairs Adelaide
Electric storage systems are reliable, but they do wear out. A failed heating element is the most common cause of no hot water on an electric system. We diagnose and replace faulty elements and thermostats, and check the anode while we’re there.
Solar hot water repairs Adelaide
Solar systems have more parts than a standard unit: roof-mounted collectors (the panels), a storage tank, a gas or electric booster, valves, and on many systems a pump and controller. When one part fails, the whole system underperforms. We repair solar hot water systems across Adelaide, from boosters and tanks to valves and collector connections.
Heat pump hot water repairs Adelaide
Heat pumps are popular in Adelaide because they use far less electricity than a standard electric system. They work like a fridge in reverse, so repairs need someone who understands the whole system. We repair heat pump hot water systems, including controller faults, fan and compressor problems, and refrigerant issues.
Continuous flow hot water repairs Adelaide
Continuous flow systems (also called instant or tankless) heat water on demand, so they never run out. They have their own weak points: flow sensors, heat exchangers, burners and ignition systems. We repair Rinnai, Bosch, Rheem and other continuous flow units across Adelaide.
Gravity fed hot water repairs Adelaide
Gravity fed (low pressure) systems are still found in many older Adelaide homes. The hot water cylinder usually sits in the roof space and is fed by a small cold water header tank, which is why the pressure at the tap is low. Repairs need someone who understands the original setup, and we work on these systems regularly.

Repair or replace your hot water system?
Sometimes a repair isn’t the right answer. Here’s how we think about it:
- Repair if the system is under 10 years old, the fault is isolated (one element, valve or thermostat), and the rest of the unit is in good condition.
- Replace if the system is over 10 to 12 years old, has been repaired several times, has a corroded or leaking tank, or the repair would cost close to half the price of a new unit.
We’ll always be straight with you. If a repair is the right call, we’ll say so. If replacement makes more sense over the next few years, we’ll tell you that too, and walk you through the options without pushing the most expensive one. Hot Water Systems Adelaide
Replacing a hot water system in SA: what the rules say
South Australia has had rules about water heater installations since 2008. For most homes, a new or replacement water heater must be a low emission type, such as a high efficiency gas, solar or heat pump system. That means you often can’t simply swap an old electric tank for a new one.
A few things to know:
- Repairs aren’t affected. Fixing your current system, replacing it under warranty, or replacing a single faulty part in a solar or heat pump system doesn’t trigger the rules.
- Rebates can help. Eligible solar and heat pump systems attract small-scale technology certificates (STCs), which reduce the upfront cost.
- You’ll get a Certificate of Compliance. Only licensed plumbers can install water heaters in SA, and your plumber must give you one for the work.
- Switching from gas to electric? You don’t have to remove your other gas appliances. If gas is connected to your property, the new electric system just needs to be a low emission type, like a heat pump.
We’ll tell you exactly which systems your home can have before you choose.
How much does hot water repair cost in Adelaide?
It’s one of the most common questions we get, and the honest answer is: it depends on what’s wrong.
- Simple repairs (element, thermostat or valve replacement) are usually straightforward and often finished in one visit.
- Gas system repairs (ignition, burner, pilot or gas control faults) vary with the fault and the parts needed.
- Solar and heat pump repairs involve more components, so diagnosis can take longer and parts are more specific.
- Urgent callouts are charged at the same rates as any other time. That’s our same rates, all day promise.
We give you a price before we start, and we don’t charge a call-out fee on hot water quotes. You’ll know what it costs before we touch anything.
How long do hot water systems last?
A well-maintained hot water system should last anywhere from 8 to 20 years, depending on the type:
| System type | Typical lifespan |
|---|---|
| Electric storage | 8 to 12 years |
| Gas storage | 8 to 12 years |
| Continuous flow (instant) | 15 to 20 years with regular servicing |
| Solar | 15 to 20 years for the tank; collectors can last longer |
| Heat pump | 10 to 15 years |
The biggest factors are water quality, how hard the system works, and maintenance. Adelaide’s water is moderately hard, so scale can build up on elements and valves over time. Storage tanks also have a sacrificial anode, a metal rod that corrodes so the tank doesn’t. Having it checked about every 5 years, and replaced when it’s worn, can add years to the life of a tank.
How to make your hot water system last longer
- Ease the relief valve lever every 6 months, as most manufacturers recommend. Check your manual first.
- Have the anode checked on storage tanks about every 5 years.
- Service gas and continuous flow units on the schedule in the manual.
- Keep the area around the unit clear, especially gas flues and heat pump air vents.
If your system is near or past the ages above and starting to play up, we’ll assess whether repair or replacement is the smarter call.
What size hot water system do I need?
Getting the size right matters. Too small and you run out. Too big and you pay to heat water you don’t use. Gas storage heats water much faster than electric, so it needs a smaller tank for the same household.
A rough guide for Adelaide households:
| Household | Electric or heat pump storage | Gas storage |
|---|---|---|
| 1 to 2 people | 125 to 160 litres | 90 to 135 litres |
| 3 to 4 people | 250 to 315 litres | 135 to 170 litres |
| 5 or more people | 315 to 400 litres | 170 litres or more |
Sizes vary by brand, tariff and how your household uses water, so treat this as a starting point.
Continuous flow systems don’t have a tank. They’re sized by flow rate in litres per minute, based on how many outlets run at once. A home with one bathroom usually suits around 16 litres per minute, and two bathrooms around 20 to 26.
When we quote a new system, we ask the right questions first: how many people, how many bathrooms, your morning routine, and whether you have solar. That’s how you get a system that suits your home.
Are heat pump hot water systems worth it in Adelaide?
For many Adelaide homes, yes. A heat pump pulls heat from the surrounding air to warm the water, rather than heating it directly with an element. It uses around a third of the electricity of a standard electric storage system.
Adelaide’s mild climate suits heat pumps well. In the colder parts of the Hills, choose a model rated for low temperatures. The upfront cost is higher than a basic electric tank, but STC rebates reduce it, and the lower running costs keep saving you money every year. If you have rooftop solar, setting the heat pump to run during the day makes it even cheaper to run.
We install, service and repair heat pump hot water systems from all major brands across Adelaide.
Does home insurance cover hot water repairs?
Policies vary, but as a general rule, damage caused by a failed hot water system (water damage to floors and walls, for example) may be covered under building insurance. The cost of repairing or replacing the system itself usually isn’t covered by standard policies.
Some policies do include hot water system replacement in specific situations. Check your Product Disclosure Statement, or call your insurer before assuming either way.
Insurers often ask for a written report on the cause of failure and the work carried out. We can prepare one on request.

- FAQ
Hot water repair FAQs
It depends on the system type, the unit you choose, and your existing setup, including whether any gas, electrical or plumbing changes are needed. SA’s water heater rules also affect which systems your home can have, and STC rebates can reduce the cost of eligible solar and heat pump systems. We’ll give you a free, no-obligation quote before any work starts.
Often not. Under SA’s water heater rules, most homes must install a low emission system, such as high efficiency gas, solar or a heat pump, when replacing. A heat pump is the usual choice if you want to stay electric. We’ll confirm what your home can have before you buy anything.
Electric and gas storage tanks usually last 8 to 12 years. Continuous flow systems can last 15 to 20 years with regular servicing. Solar systems last 15 to 20 years, and heat pumps 10 to 15. Regular maintenance, especially checking the anode on storage tanks, helps them last longer.
For most of metro Adelaide, yes, we can get to you the same day, and many repairs are finished in one visit. If a part needs to be ordered, we’ll tell you how long it will take.
If the system is under 10 years old and the fault is isolated, repair is usually the right call. If it’s over 10 to 12 years old, has been repaired several times, or the repair costs close to half the price of a new unit, we’ll recommend replacement and explain why. We won’t push you into a new system you don’t need.
As a rough guide, a 250 to 315 litre electric or heat pump tank, or a 135 to 170 litre gas storage tank. A continuous flow unit is sized by flow rate instead: around 20 to 26 litres per minute for a home with two bathrooms. We’ll size it properly when we come out.
Yes. Gravity fed systems are common in older Adelaide homes, and we repair them regularly.
Water heating is usually the second-largest energy use in an Australian home after heating and cooling, at roughly 15 to 27% of household energy. A heat pump uses around a third of the electricity of a standard electric tank. Solar hot water uses the sun for most of the heating, with a gas or electric booster for cloudy days.
Yes. Let us know when you call and we’ll apply the pensioner discount to your quote.
