A hot water system usually gets attention when it stops working, starts leaking or no longer keeps up with the household. Coffison Plumbing, Electrical & Air installs, repairs and replaces gas, electric, heat pump and solar hot water systems across the Redcliffe Peninsula, Moreton Bay and North Brisbane, for houses, units and managed buildings.
Hot water system replacements are completed by licensed trades, with the required compliance paperwork handled as part of the job.
Every hot water call starts with an assessment of the existing unit before repair or replacement options are recommended. Our vans carry common elements, thermostats, valves and fittings, helping the team complete many repairs on the first visit. A temporary hot water unit may also be available where a full replacement takes longer.
Related work such as gas appliance installation and water leak detection is handled by the same licensed team, so related plumbing or gas issues can be assessed at the same time.
New systems sized to the household, supplied and installed with the old unit removed.
Elements, thermostats, gas control valves, thermostatic mixing valves, relief valves and leaking connections.
Anode inspection, relief valve checks and flushing to help maintain the system and identify developing faults.
Storage to continuous flow, electric to heat pump, or a like-for-like swap on the same day where stock allows.
Failed units, no hot water, scalding water or leaking cylinders, with 24/7 service available.
Staged replacement programs and access coordination for tenanted and shared buildings.
Gas, electric storage, heat pump and solar systems each suit different properties. The right option depends on the energy available at the property, installation space, household hot water demand and budget.
Gas continuous flow can suit households with higher or frequent hot water demand. Electric storage offers a straightforward replacement option for many existing systems. Heat pumps can reduce electricity use compared with conventional electric storage, while solar hot water can suit properties with suitable roof space and solar exposure.
| System Type | Often Suits | Things to Consider |
|---|---|---|
| Gas continuous flow | Homes with a suitable natural gas or LPG supply and regular hot water demand | Gas supply, flow rate and household demand |
| Electric storage | Smaller households, unit blocks and properties without gas | Tank size, tariff and available installation space |
| Heat pump | Households looking to reduce electricity use for water heating | Outdoor position, airflow, noise and upfront cost |
| Solar with boost | Properties with suitable roof space and solar exposure | Roof orientation, collector condition and backup heating |
Gas continuous flow units heat water as it passes through, so there is no storage cylinder holding a fixed volume of hot water. They can suit larger households and homes with regular hot water demand, provided the gas supply is suitable.
The existing gas line and supply need to be checked when sizing a new system, particularly when replacing a different type or capacity of unit.
An electric storage system can be a straightforward replacement where the property already has an electric cylinder. It remains common across units and older homes in Clontarf, Margate and Woody Point.
Tank size, household demand and the electricity tariff all need to be considered when choosing a replacement.
A heat pump moves heat from the outside air into the cylinder instead of relying solely on a conventional electric element. This can substantially reduce the electricity used for water heating compared with a standard electric storage system.
It needs an outdoor position with suitable airflow, and placement should also consider operating noise and nearby windows or living areas.
Solar hot water systems use roof-mounted collectors, generally with gas or electric boosting when required. The condition and position of the collectors, roof space and existing plumbing all need to be considered when repairing or replacing a system.
Our licensed plumbers install new solar hot water systems and repair existing systems, including boost element and valve faults.
Whether a hot water system should be repaired or replaced depends on its age, condition, fault history and the cost of the repair. A failed element, thermostat, valve or connection may be repairable, while a leaking cylinder or repeated faults can make replacement the more practical option.
We assess the existing unit and explain the available options before work begins, so you can compare repair and replacement where both are viable.
| What to check | Usually repair | Usually replace |
|---|---|---|
| Age of unit | Relatively new and otherwise in good condition | Older and approaching the end of its service life |
| Where the water is coming from | A valve, fitting or connection | The cylinder body itself |
| Fault history | Isolated fault | Repeated faults or callouts |
| Water quality | Clear | Rusty or discoloured at the hot tap |
| Parts | Parts remain available | Superseded or unavailable |
No hot water, scalding water and a leaking tank may need urgent attention, and our team provides 24/7 plumbing service across the Redcliffe Peninsula.
Common faults can often be diagnosed and repaired during the initial visit, depending on the problem and parts required. Every system is tested after the repair before the job is completed.
Where a tank has split and caused water damage, the same visit can also address the burst pipe and water damage side of the problem. The wider 24/7 emergency plumbing service covers other urgent plumbing issues around the property.
We work across a range of major hot water brands, giving property owners options when repairing or replacing an existing system.
The team installs and services Rheem, Rinnai, Dux, Thermann, Bosch, Aquamax, Everhot, Solahart and Saxon. If your existing unit is one of these, have the model number from the data plate ready when you call to help identify the system and required parts.
Hot water installation and replacement work needs to meet Queensland plumbing requirements. Our licensed plumbers complete the applicable compliance requirements and paperwork as part of the installation.
Where the installation is classed as notifiable work, the required documentation is lodged following completion.
Storage systems require appropriate pressure and temperature relief provisions as part of a compliant installation.
Where required, temperature control is installed and checked as part of the changeover.
Gas hot water installations are completed by licensed gas fitters with the applicable gas compliance requirements completed.
If a gas fault is identified during a hot water job, such as a suspected leak or appliance fault, it can be handled through our gas repairs service rather than left for another visit.
A straightforward like-for-like replacement can often be completed on the same day, subject to the required unit being available. A changeover between system types can take longer because it may involve new gas or electrical connection points, changes to the installation area or relocation of the unit.

Installation time depends on the system and whether the existing connections can be reused. A straightforward like-for-like replacement can often be completed on the same day, while changing system type may require additional plumbing, gas or electrical work.
Often, depending on the system required, stock availability and the work involved. We can advise what is possible after assessing the existing unit and replacement requirements.
Sizing depends on household size, peak hot water demand and the type of system being installed. Our team assesses these requirements before recommending a replacement.
It depends on the system type, brand, installation requirements and how accessible the location is. We quote in writing before any work begins, so you know the scope and cost before approving the installation.
