Continuous Flow Hot Water System Installation โ Labour Only
This installation package covers the professional labour required to replace an existing external continuous-flow gas hot water system with your purchased replacement unit, subject to the existing plumbing, gas supply, electrical supply and installation location being suitable.
The hot water system, valve kits, additional fittings, pipework and upgrade components are purchased separately. If you have added the required products to your Installed Today order, our installation team fits them as part of the applicable installation scope.
This standard service is designed around a like-for-like, ground-floor external replacement. Relocations, undersized gas services, new electrical circuits, new power points, major pipework changes and other non-standard work require the matching add-on or prior approval.
Where a valve kit is purchased with the installation, the package also includes up to 2 metres of associated pipework installed as part of fitting the purchased valve kit.
What Is Included in the Continuous Flow Installation?
Replacement Installation Labour
Professional installation of your purchased continuous-flow gas hot water system as a standard external replacement where the existing site and services are suitable.
Purchased Accessories Fitted
Purchased valve kits and approved accessories can be fitted as part of the installation where they are compatible with the selected system and site.
Gas Connection & Commissioning
The new appliance is connected to the existing suitable gas service, tested and commissioned by the appropriately licensed gas fitter.
Water Connections
The existing suitable hot and cold water services are connected to the replacement system, together with separately purchased valves or fittings where required.
Old Unit Removal From Position
The existing water heater is disconnected and removed from its installed position. Off-site disposal or recycling is a separate add-on unless specifically included in the order.
Compliance Process
The applicable plumbing notification and gas compliance documentation for the installation work completed are handled by the relevant licensed trades.
What Happens If You Purchase a Valve Kit?
Where the matching valve kit is purchased with the continuous-flow installation, we install the purchased valve components and include up to 2 metres of associated pipework installed as part of that valve-kit installation.
This can help provide a neat replacement arrangement where the existing valves need to be replaced or the new continuous-flow unit has connection points that differ slightly from the old unit.
What Counts as a Like-for-Like Continuous Flow Replacement?
For this installation package, a like-for-like replacement means an existing continuous-flow gas water heater is being replaced with another compatible continuous-flow gas water heater in the same external installation area, using the existing service routes where they remain suitable.
- Continuous flow replaced with continuous flow
- Same general external installation location
- Ground-floor installation
- Existing gas service is suitable for the replacement appliance
- Existing water services are reasonably accessible

Does the Existing Gas Supply Need to Suit the New System?
Yes. A continuous-flow water heater can require a substantial gas input, and the existing gas system must be capable of supplying the selected appliance correctly.
The licensed gas fitter needs to consider the existing gas pipework, available gas pressure, meter or LPG supply arrangement and the gas demand of the new appliance.
A replacement system with a higher gas demand should not simply be connected because the existing water heater previously worked from the same pipe.
Is Gas Compliance Certification Included?
The gas work associated with installing the replacement continuous-flow appliance is completed by an appropriately licensed gas fitter.
For applicable Queensland gas-system installation or alteration work, the gas fitter completes the required gas compliance process and provides the applicable gas system compliance certificate for the work performed.
If an existing gas defect or unsafe condition is identified, additional rectification can be required before the new appliance can be safely commissioned.
Is a QBCC Form 4 Required?
In Queensland, installing or replacing a water heater in an existing building is generally classified as notifiable plumbing work.
For work completed under this category, the licensed plumber registers the work with the QBCC using the applicable Form 4 process after the work is completed.
For a standard Installed Today replacement where the work is classified as notifiable, the applicable Form 4 registration process and relevant lodgement fee are included within the installation package.
Does Every Continuous Flow Installation Need a New Tempering Valve?
Not automatically.
The completed hot-water installation must provide compliant delivery temperatures at the outlets that require temperature control, but the method used depends on the selected water heater and the property's existing plumbing arrangement.
Some installations may already have a suitable compliant temperature-control device. Other installations may require a new tempering or temperature-control valve because of the temperature delivered by the new appliance or the condition of the existing plumbing.
If a new temperature-control device is required and is not already included in your purchased products, it must be added to the installation scope.
Can the Existing Valves Be Reused?
Existing valves and fittings can only remain where they are suitable, serviceable and compatible with the replacement installation.
Depending on the appliance, property and incoming water pressure, the installation may require items such as:
- Water isolation valve
- Gas isolation valve
- Required non-return protection
- Pressure-control equipment where required
- Temperature-control equipment where required
- Manufacturer-specified connection fittings
If existing components are leaking, seized, damaged, incorrectly positioned or otherwise unsuitable, the relevant replacement components need to be purchased before the installation can be completed within the agreed scope.
Does the Existing Installation Location Need to Be Compliant?
Yes. Reusing the old location does not automatically mean the location is suitable for the replacement appliance.
The new continuous-flow system must be capable of being installed in accordance with its manufacturer instructions and the applicable gas-installation requirements.
The installer needs to consider matters including:
- Required clearance from building openings
- Air intake and exhaust requirements
- Clearance from windows and doors
- Clearance from vents and other building features
- Service and maintenance access
- Gas and water connection access
- Electrical access where applicable
- Manufacturer installation requirements
Is This Package for External Continuous Flow Systems?
Yes. The standard installation package is based on a ground-floor external continuous-flow replacement.
Where an approved internal continuous-flow installation pathway is available, it must be separately selected and must account for the appliance's flue, combustion-air, clearance and other installation requirements.
An external water heater should not be installed internally simply because it physically fits inside the proposed space.
What If the Continuous Flow System Needs Electricity?
Many continuous-flow gas water heaters use mains electricity for ignition, controls, fans or other appliance functions.
For a standard replacement, the existing electrical supply must be suitable for the new appliance and located where the manufacturer permits.
Where electrical disconnect and reconnect work is required, it can only be performed by a person whose electrical licence authorises that work.
Restricted electrical licences can authorise certain incidental disconnect and reconnect work associated with hot water or gas-appliance trades, subject to the specific conditions on the licence.
What If the Old Continuous Flow Unit Did Not Need Power?
If the replacement system requires mains electricity and the existing installation does not already have a suitable electrical supply, separate electrical work is required.
Depending on the selected appliance and property, this may mean adding a new suitable power point, extending an existing circuit or installing another appliance-specific electrical arrangement.
The electrical requirement should be identified before installation wherever possible so the correct electrical package can be purchased with the order.
What Access Is Included in the Standard Installation?
The standard installation assumes the existing and replacement water heater positions are ground-floor, external and reasonably accessible.
The installer needs a safe route to move tools, equipment and the replacement appliance between the service vehicle and installation position.
A prepaid $300 two-person handling and difficult-access fee applies where the job requires additional labour because of conditions such as:
- Stairs
- Steep driveways
- Steep blocks
- Restricted side access
- Difficult carrying routes
- Awkward lifting or positioning
- Additional manual handling
- Other pre-approved difficult-access conditions
If you are unsure whether the standard-access conditions apply, send clear photos of the existing water heater, access route and proposed replacement position to help@installedtoday.com.au before ordering.
Is Removal of the Existing Water Heater Included?
Yes. The labour package includes disconnecting the existing unit and removing it from the installation position as part of the replacement work.
Off-site disposal and recycling are separate. If you want the old water heater taken away from the property for disposal or recycling, select the applicable disposal add-on at checkout.
What Can Turn a Standard Replacement Into Additional Work?
Gas Supply Changes
The new unit requires more gas than the existing service can provide, or the existing gas pipework is damaged, undersized or otherwise unsuitable.
Electrical Changes
The replacement unit needs a new GPO, circuit extension, dedicated circuit, switchboard work or other fixed electrical installation work.
Plumbing Changes
Major rerouting, relocation, additional pipework or replacement of defective existing plumbing is required.
Location Changes
The existing location cannot satisfy the new appliance's clearances, or the customer wants the system installed elsewhere.
Compliance Upgrades
Existing valves, temperature-control arrangements, gas equipment or plumbing components cannot be reused compliantly.
Difficult Access
The job requires additional people, carrying, lifting or access arrangements beyond the standard ground-floor external installation.
We Install What You Buy
The continuous-flow labour package is designed to make the installation scope clear before the technician arrives.
You purchase the water heater and any required valve kit, accessory, gas upgrade, electrical work, disposal or other add-on separately. The installation team then completes the purchased installation scope using appropriately licensed trades.
For a straightforward external continuous-flow replacement with suitable existing gas, plumbing, electrical supply and access, this creates a simple pathway from online purchase to completed installation without automatically bundling materials or upgrades that the property may not need.
What Should Be Checked Before You Purchase Installation?
- The existing system is a continuous-flow gas water heater
- The replacement is suitable for the same external location
- The gas type matches the intended installation
- The existing gas service can support the new appliance
- The new system can meet required clearances

Can You Install a Different Type of Hot Water System Under This Package?
No. This specific package is for a standard continuous-flow replacement. Converting to gas storage, electric storage or heat-pump hot water requires the appropriate installation package and any necessary gas, electrical, plumbing or base work.
What If the Existing System Is Non-Compliant?
The new installation cannot simply reproduce a defective or unsuitable existing arrangement. Any work necessary to provide a suitable new installation must be completed or added to the scope.
Does the New Unit Have to Fit in Exactly the Same Position?
The package assumes the same general external installation area. Minor connection differences can be accommodated within the purchased scope where practical, but a genuine relocation is additional work.
What If the New Unit Is Larger Than the Old Unit?
The replacement still needs to satisfy its manufacturer clearances, access requirements and service needs. If the existing location cannot accommodate those requirements, additional work may be necessary.
Is This Continuous Flow Installation Package Right for Your Job?
Choose this installation package where you are replacing an existing continuous-flow gas hot water system with another compatible continuous-flow unit in the same ground-floor external installation area.
The standard labour scope covers professional installation of the purchased system, fitting purchased accessories, connection to suitable existing services, commissioning, removal of the old unit from its installed position and the applicable plumbing and gas compliance process.
Required valves, fittings and materials remain separate purchases. A purchased valve kit includes up to 2 metres of associated pipework installed under the package terms.
Before ordering, confirm that the existing gas supply, water services, appliance clearances, electrical supply and access are suitable. If gas upgrades, electrical work, relocation, difficult access, disposal or additional materials are required, add the matching service before installation.
