Cold shower this morning? Start here
A hot water problem announces itself in a handful of ways, and the first question is always the same: is the system failing, or has it failed?
- No hot water at all Is the symptom page for a total loss, including the make-safe steps and what to check before you call.
- Hot water repair Is for systems worth saving: a failed element, a faulty valve, a pilot light that will not stay lit.
- Hot water replacement Is for heaters winding down after decades of work, where every fix buys weeks rather than years.
- Hot water installation Is for new systems, renovations and relocations where nothing exists yet.
Guess wrong between those four and it costs money. This hub also carries the decision content: choosing gas versus electric versus instant, sizing a system to your household, and reading the signals that separate a repair from a replacement. If water is leaking from the tank body itself, treat it as urgent and call now.
Station-side flats and the shared-laundry problem
Carlton's hot water story is written in two housing eras, and the flats tell one half of it. The post-war brick blocks between the railway station and Princes Highway run ageing storage units in shared laundries, and those heaters are steadily reaching the end of their service life.
They tend to fail completely rather than fade. A whole building wakes up cold on the same morning, and suddenly strata needs a plumber who can quote, book and swap the unit with a dozen households watching.
That is routine work for us. The vans carry the popular storage models and the fittings older laundries need, and the fixed price covers the complete changeover, not just the tank.
Landlords and owners' corporations get the compliance paperwork with the invoice, and tenants get their hot shower back the same day.
The six hot water services, at a glance
- Hot water repair: elements, valves, thermostats and pilot lights on systems worth saving.
- Hot water replacement: like-for-like or upgraded swaps for heaters that have given all they have.
- Hot water installation: new systems for renovations, extensions and first-time setups.
- Gas hot water systems: tank and continuous-flow units running on natural gas.
- Electric hot water systems: storage units on continuous or off-peak tariffs.
- Instant hot water systems: continuous flow units that warm the water the moment a tap opens.
Jubilee Avenue cottages and the other half of the story
The other era lives in the Federation and interwar cottages on the older grid, and their hot water pattern is different. Many still run a storage unit retrofitted into a house built decades before indoor hot water was standard: squeezed into a corner, a cupboard or the old rear washhouse.
Unrenovated places can still have galvanised steel in the supply lines. When one of those systems dies, the replacement is a chance to fix the whole setup, not just the heater.
The cottages also suit instant systems better than most suburbs. A wall-mounted continuous flow unit frees the floor space an ageing tank has squatted on for half a century, and it sidesteps the pressure and pipe-size quirks of the older services.
That comparison, storage versus instant in an older house, is one we walk homeowners through every week.
Hot water repair
Repair suits systems with years left in them. A failed element, a leaking temperature relief valve, a thermostat cutting the heat short or a pilot light that refuses to stay lit: each is a discrete fix on a sound tank, usually finished in a single visit.
- Faults diagnosed on the spot, not guessed at over the phone
- Genuine replacement parts for the major brands
- Honest advice when the tank itself is the problem
Hot water replacement
Replacement is the right call when the maths stops working. A storage unit near the end of its life starts failing in pieces, and every repair buys weeks, not years. We assess the tank, quote the swap, and can usually change the unit over the same day.
- Like-for-like swaps or upgrades to a different fuel or format
- Old unit taken away, new one commissioned and tested
- Fixed written price covering the complete changeover
Hot water installation
Installation is for places where nothing exists yet. Renovations, extensions, garage conversions and new laundries each need a heater selected, matched to demand and piped in from the ground up, which is a different job from a swap and gets quoted as one.
- System selection matched to the household and the fuel available
- Full pipe runs, isolation taps and pressure sorted
- Compliance certificates sorted with every invoice
Gas hot water systems
Gas heats fast and recovers quickly for big households. Where natural gas is available, tank and continuous-flow gas units both earn their place, and the gas systems page compares them honestly, including the considerations that come with a gas appliance in an older house.
- Natural gas tank and continuous-flow choices
- Gas leak awareness built into every install
- Honest comparison against electric for your usage
Electric hot water systems
Electric suits smaller homes and off-peak tariffs. For units and compact cottages, an electric storage unit heating overnight at a lower tariff can be the economical choice, and the electric systems page explains when that holds and when it does not.
- Continuous and off-peak tariff setups explained
- Sizing for one-bathroom homes and flats
- Element and thermostat repairs on existing units
Instant hot water systems
Instant units never run out and never store. Continuous flow systems heat the water the instant a tap turns on, which means no storage tank to fail, no standby heat loss, and endless hot water for the households that need it.
- Endless flow for back-to-back showers
- Wall-mounted formats that free up floor space
- Sizing by simultaneous taps, not by tank litres
Choosing a system: gas, electric or instant
This is the depth question most hot water pages skip, and it is where the real money is decided. The short version: there is no best system, only the best system for your house, your household and your fuel.
Gas storage
Electric storage
The three system pages carry the full comparison. The honest advice is to read them before you buy, not after, because the biggest cost in a hot water job is choosing wrong and living with it for a decade.
Sizing a system to your household
Tank size and flow rate are where generic advice fails real families. A one-bathroom flat near the station has different needs from a four-bedroom cottage with teenagers.
Too small fails daily; too big wastes money heating water nobody uses. We size by bedrooms, bathrooms and simultaneous use, not by rule of thumb.
- Storage systems: litres and recovery rate
- Instant systems: litres per minute across the taps that run at once
The sizing conversation takes five minutes on the phone and saves years of lukewarm showers.
Repair or replace: reading the signals
Every hot water job starts with the same honest question: is this system worth saving? The signals are consistent.
Age
A storage unit near or past its typical life is on borrowed time, and repairs to it are money spent on a departure.
Leaking tank
Water from the tank body is terminal; no repair fixes corroded steel.
Repeated faults
One element in five years is a repair. Two valves in two years is a system telling you something.
Rusty or discoloured hot water
That can be the tank sacrificing its anode, which is a replacement signal, not a filter problem.
When the answer is replace, the replacement page covers the swap end to end. When the answer is repair, the repair page does the same. What we never do is sell the bigger job because it is the bigger job.

Good questions, straight answers
Hot water questions Carlton locals ask
How do I know whether to repair or replace my hot water system?
Age is the honest guide, because a storage unit past its service life costs more to keep patching than to replace, and we assess the tank, valve, element and pressure on-site before quoting either way.
Can you service the shared laundry system in our flats near the station?
Yes, strata and landlord work is routine for us, and the ageing heaters in those post-war blocks are exactly the kind of job we quote, book and complete with minimal disruption to tenants.
Which costs less to run, gas or electric hot water?
Gas generally heats for less per litre with bigger families, while electric storage suits smaller homes and off-peak tariffs, and we run the comparison against your actual usage rather than a generic answer.
Do you install instant hot water systems in older Federation houses?
We do, and the older cottages often benefit most because a wall-mounted instant unit frees the cupboard or corner an ageing tank has occupied for decades.
How long does a system swap take from start to finish?
Most straight changeovers finish the same day we begin, since our vans are stocked with the common models and their fittings, and the written price covers the whole job before a tool comes off the van.
Is a total loss of hot water an emergency?
A total loss is treated as urgent, especially with children or elderly residents in the house, and the symptom page explains the make-safe steps while a plumber is on the way.
