AquaMAX 125L Electric Hot Water System – 981125G4 & 981125G7
The AquaMAX 125L Electric Hot Water System is a compact mains-pressure electric storage water heater designed for smaller households, units, townhouses and replacement installations where a larger storage cylinder is unnecessary.
The current AquaMAX public range lists the 981125G4 with a 1.8kW element and the 981125G7 with a 3.6kW element. Both provide 125 litres of hot-water delivery, single-element operation, dual-handed water connections and suitability for indoor or outdoor installation.
Installed Today offers the AquaMAX 125L as a supply-only water heater or with supply and installation across eligible Brisbane and Gold Coast service areas.
About the AquaMAX 125L VE Electric Water Heater
The AquaMAX 125L forms part of the manufacturer's vitreous-enamel electric storage range. It stores electrically heated water ready for use and operates as a conventional mains-pressure storage water heater.
AquaMAX positions the 125L as a practical option for smaller families and warmer climates, providing more stored hot water than compact 50L and 80L systems without moving into the larger 160L class.
The current models are single element and use dual-handed hot and cold water connections to provide flexibility on compatible replacement installations.

The supplied Installed Today page also referenced model 981125G4/BL. AquaMAX's current public 125L product page lists 981125G4 and 981125G7 as the current model options, so availability of any additional suffix variant should be confirmed before ordering.
Who Is the AquaMAX 125L Best For?
Smaller Households
AquaMAX publishes a maximum guide of up to four people under the manufacturer's stated household-use assumptions.
Compact Electric Replacements
The 125L can suit replacement of a compatible smaller electric storage water heater where the location, plumbing, electrical supply and pressure requirements remain suitable.
Units & Townhouses
Its relatively narrow upright footprint can suit selected apartments, townhouses, granny flats and rental properties with moderate hot-water demand.
How Many People Is the AquaMAX 125L Suitable For?
AquaMAX publishes a maximum household guide of up to 4 people.
The manufacturer's feature information bases this figure on seven-minute showers at 42°C mixed-water temperature in a moderate climate on a time-of-use tariff.
The current AquaMAX specification table labels its four-person figure as based on a continuous tariff, so the published tariff descriptions are not completely consistent.
For that reason, the four-person figure should be treated as a manufacturer sizing guide rather than a guarantee. Actual suitability depends on shower duration, baths, fixture flow rates, appliance use, climate and the hours of electricity available for reheating.
AquaMAX 125L Key Details
*Household sizing depends on actual usage. AquaMAX currently advertises a 10-year cylinder warranty and 12 months parts-and-labour warranty, with full manufacturer conditions applying.
Key Features of the AquaMAX 125L
Vitreous Enamel Cylinder
The steel storage cylinder uses an internal vitreous-enamel lining as part of AquaMAX's cylinder-protection system.
Dual-Handed Plumbing
Hot and cold water connections are provided to assist compatible left- or right-side replacement installations.
Mains-Pressure Operation
AquaMAX identifies its electric vitreous-enamel range as mains-pressure water heaters for conventional household hot-water delivery.
Single Element
The current 125L models use a single heating element, with 1.8kW and 3.6kW configurations available.
Indoor or Outdoor
AquaMAX specifies the current 125L VE water heater as suitable for indoor or outdoor installation.
Compact Upright Format
The 1250mm-high, 480mm-wide cabinet can suit selected replacement locations where larger electric cylinders are unsuitable.

Allow additional space for water valves, pipework, electrical access, drainage and future servicing rather than relying only on the cabinet dimensions.
AquaMAX 125L Water Pressure Requirements
AquaMAX specifies a 1000 kPa relief-valve pressure for the current 125L models.
Where an expansion-control valve is required, AquaMAX specifies an 850 kPa ECV and a maximum water-supply pressure of 680 kPa.
Without an ECV, the maximum published water-supply pressure is 800 kPa.
Where the property's water pressure can exceed the permitted limit, suitable pressure-control equipment must be selected as part of the installation.
Flexible Replacement Plumbing
AquaMAX describes the 125L VE as dual handed, with inlets and outlets arranged to simplify compatible replacement installations.
This can reduce unnecessary plumbing changes where the existing hot and cold pipework approaches from a particular side of the water heater.
Dual-handed connections do not guarantee a direct replacement. Existing valves, pipe locations, drainage, pressure controls and service access still need to be assessed.
1.8kW or 3.6kW?
981125G4 – 1.8kW
The lower-output configuration has a maximum loading of 1800W and will recover more slowly than the 3.6kW version.
981125G7 – 3.6kW
The higher-output configuration has a maximum loading of 3600W and provides faster reheating where the electrical installation can support it.
Do not change element rating solely to increase recovery speed. The electrical circuit, cabling, protective devices and tariff arrangement must suit the selected model.
Can the AquaMAX 125L Be Installed Indoors or Outdoors?
Yes. AquaMAX lists the 125L VE electric water heater as suitable for indoor or outdoor installation.
The installation position must provide suitable structural support, plumbing, electrical connection, drainage and service access.
Where leakage could cause property damage, appropriate tray and drainage arrangements may be required as part of the compliant installation.
Check the Electricity Tariff Before Sizing
The AquaMAX 125L household guide should be considered together with the property's electricity tariff and actual daily demand.
A continuously powered water heater can reheat as hot water is used, while a time-controlled or off-peak installation may only have electricity available during nominated periods.
Where electricity availability is restricted, the stored hot-water volume must cover household demand between heating cycles.
What Is Required to Install the AquaMAX 125L?
AquaMAX states that installation requires a plumber, and all plumbing and electrical work should be completed by appropriately qualified trades in accordance with the manufacturer's instructions and applicable requirements.
- Correct 981125G4 or 981125G7 model selected
- Suitable level and stable installation position
- Rp 3/4 compatible water pipework
- Correct 1000 kPa relief-valve arrangement
- 850 kPa expansion-control valve where required
- Pressure limiting where incoming supply pressure requires it
- Suitable isolation and non-return valve arrangement
- Compliant relief-valve drainage
- Tray and drainage where required by the installation
- Suitable delivery-temperature control where required
- Electrical circuit matched to the selected element load
- Permanent electrical work by a qualified electrical worker
- Suitable access to valves and service components
- Indoor or outdoor installation position that meets current requirements
AquaMAX 125L vs 160L Electric Storage
| Feature | AquaMAX 125L | AquaMAX 160L |
|---|---|---|
| Hot Water Delivery | 125L | 160L |
| Maximum Household Guide | Up to 4 people | Up to 5 people |
| Height | 1250mm | 1610mm |
| Width | 480mm | 480mm |
| Depth | 515mm | 515mm |
| Element Options | 1.8kW / 3.6kW | 1.8kW / 2.4kW / 3.6kW |
The 160L offers more stored hot-water delivery but is significantly taller. Actual household demand and tariff should determine sizing rather than occupant count alone.

Tempering Valve and Element Information
*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.
If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.
Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.
Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.
1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.
This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.
Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.
**Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.
A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.
If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.
If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.
Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.
It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
