Hot water help for Logan homes
A hot water problem rarely arrives at a convenient moment. One morning the shower runs cold, or you find a damp patch spreading out from under the unit on the side of the house. Whatever has gone wrong, the first job is a proper diagnosis — not a guess and a replacement part.
We look after hot water work for households right across Logan. That covers straightforward repairs, full system replacement when a unit has reached the end of its life, and new installations. Everything is carried out by licensed tradespeople, and gas work is completed by a qualified gas fitter.
Hot water repairs
Elements, thermostats, valves, ignition faults and leaking connections. We test the unit first and explain what we have found before any work goes ahead.
Replacement
When a tank has failed there is no repair available. We remove the old unit, make good the connections and commission the new system properly.
New installation
Installing a hot water system where none exists, or relocating one during a renovation, including the associated gas or water pipework.
Signs your hot water system needs attention
Hot water units usually give warning before they fail completely. Acting on the early signs often keeps the job in repair territory rather than replacement.
- No hot water at any tap in the house
- Water that starts hot and turns cold within minutes
- Temperature that swings between scalding and lukewarm
- Water pooling underneath or around the unit
- Rust-coloured or discoloured hot water
- Rumbling, knocking or hissing from the tank
- A pilot light or ignition that will not stay lit
- A relief valve that constantly drips or discharges
If you can smell gas near a gas hot water unit, do not attempt to relight it. Turn the gas off at the meter if it is safe to do so, keep the area ventilated and call us straight away.
Repair or replace?
This is the question almost every customer asks, and the honest answer depends on what has actually failed and how old the unit is.
Repair usually makes sense when
- • The unit is comfortably within its expected service life
- • The fault is an element, thermostat, valve or ignition part
- • The tank body itself is sound and not weeping
- • The system still suits the size of your household
- • It is the first significant fault the unit has had
Replacement is the better call when
- • The cylinder is leaking from the body rather than a fitting
- • The unit is well past its expected life and failing repeatedly
- • Repair costs are approaching the price of a new system
- • The tank can no longer keep up with the household
- • Parts for an older model are no longer readily available
We will give you the realistic picture either way. If a repair will genuinely buy you several more years, we will say so. If you are about to spend good money on a tank that is on borrowed time, we will say that too.
Gas and electric hot water
Gas hot water
Common in Logan homes with an existing gas connection. Faults tend to sit around ignition, the pilot assembly, the gas supply or the valve. Any work on the gas side must be carried out by a qualified gas fitter, which is work we handle in-house alongside our gas fitting services.
Electric hot water
Still the most widespread type across the region. Electric storage units are generally simple to diagnose, and element or thermostat faults are among the most frequent repairs we attend. Sizing matters here — an undersized tank will always feel like it is running out.
We will work with what your home already has connected and recommend the practical option rather than pushing a particular product.

Hot water FAQs
Why has my hot water suddenly stopped working?
On an electric unit it is usually a tripped circuit, a failed element or a faulty thermostat. On a gas unit it is more often a pilot or ignition fault, a gas supply problem or a failed thermocouple. A licensed plumber can test the unit and tell you which fault you are dealing with before any parts are ordered.
Is it worth repairing an older hot water system?
If the tank itself is sound and the fault is an element, thermostat, valve or ignition component, a repair is usually the sensible choice. Once the cylinder is leaking from the body, repair is no longer possible and replacement is the only safe option.
How long should a hot water system last?
Most storage systems in South East Queensland give around eight to twelve years of service. Water quality, tank material and whether the sacrificial anode has ever been replaced all shift that figure either way.
Why does my hot water run out so quickly?
Common reasons are a failed lower element on an electric unit, a thermostat set too low, sediment reducing the usable volume in the tank, or a household that has simply outgrown the tank size it was fitted with years ago.
