Build Your Optional Supply & Install Package

Answer a few quick questions to confirm whether you can order this package online or need a quick install check first.

Are you replacing an existing hot water system?
This helps us work out whether this looks like a standard replacement.
Are you replacing the same hot water system, identical make and model?
If yes, the valve kit is recommended. If not, it is required at the end.
Is it going in an existing location?
Existing location means the new system goes back in the same general position.
Where is the system located?
If outside, continue. If inside or under a house, complete the 60sec Check first.
Are you changing system type, electrical connection type or needing to extend your electrical connection?
If yes, an electrical extension or new circuit may be needed, or you can organise your own electrician.

Do any site access issues apply?
If any access issue applies, we will add the 2-man install option and continue.
Does your current installation meet current compliance requirements?
If no or unsure, we will recommend a valve kit or extra works as the safer starting point.

      Frequently Asked Questions

      Can I buy the AquaMAX 315L supply only?

      Yes. You can buy the AquaMAX 315L as a supply-only product if you already have a licensed installer arranged. The unit-only price does not include installation, old system removal, disposal, valve kits, electrical work, plumbing alterations or compliance upgrades unless selected separately.

      Yes. Supply and install options are available in selected Brisbane service areas. Complete the installation check to confirm whether the standard installation option suits your property and whether additional add-ons may be required.

      Can I get the AquaMAX 315L installed in Gold Coast?

      Yes. Selected Gold Coast service areas are available. Installation suitability depends on access, existing plumbing, electrical requirements, drainage, valve condition, compliance and selected add-ons.

      Is installation included in the product price?

      No. The main product price is the unit-only price. The installed-from price is shown separately so you can compare supply only against supply and install.

      What does the installed-from price include?

      The installed-from price is based on the AquaMAX 315L unit plus the matching standard installation option. Final pricing may vary depending on valve kits, removal or disposal selections, pipework, electrical work, access, compliance and other selected add-ons.

      Do I need a valve kit?

      Many hot water replacements require compatible valves to meet installation and compliance requirements. The installation check helps identify whether a valve kit is recommended for your order.

      How many people is the AquaMAX 315L suitable for?

      AquaMAX lists the 315L VE electric water heater as suitable for up to 9 people, based on 7-minute showers at 42°C mixed water temperature in a moderate climate on a time-of-use tariff. Actual suitability can vary depending on shower length, water usage, tariff setup, climate and household habits.

      Can the AquaMAX 315L be installed outside?

      Yes. AquaMAX lists the 315L VE electric water heater as suitable for indoor and outdoor installation, provided the installation location is compliant and suitable.

      What is the warranty on the AquaMAX 315L?

      AquaMAX lists a 10-year cylinder warranty and 12 months parts and labour warranty for the AquaMAX 315L VE electric water heater, subject to warranty terms and conditions.

      Is the AquaMAX 315L good for replacing an old electric hot water system?

      Yes. The AquaMAX 315L is designed as a practical electric water heater replacement for medium to large families with a big demand for hot water. It is a good option where the existing system size, location, plumbing and electrical setup are suitable for a 315L electric storage hot water system.

      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.

      Installed Today supplies the product and helps arrange installation through licensed installation partners where available. Installation is only available on selected products and in eligible service areas.

      The install package price applies to the selected installation scope shown at checkout. Final suitability still depends on site access, existing plumbing or electrical setup, valves, drainage, compliance requirements, product suitability and any extra work required.

      If something outside the selected package is needed, it will be discussed before proceeding.

      Supply-only orders do not include installation, old unit removal, disposal, valve kits, electrical work, plumbing alterations or compliance upgrades unless these are clearly selected or included in your order.

      Buying a new hot water system, water filter, pump or plumbing product should be clear, simple and easy to organise.

      Installed Today helps you compare products, check supply-only pricing and, where available, build an optional installation package before checkout.

      Whether you already know exactly what you need or you are still comparing options, Installed Today gives you a clearer way to buy the right product for your home, budget and timing.

      Why Customers Choose Installed Today

      Clear Pricing Before Checkout

      See the product price upfront, then review available installation options and common add-ons before placing your order. You can check the package total before checkout, instead of waiting on basic pricing just to get started.

      Common Installation Add-Ons Available

      Designed to Make Your Decision Easier

      Choose an optional supplied and installed package where installation is available and you want the product and selected install options organised in one order.

      It is a simpler way to organise the product, the selected extras and the parts of the job that matter most.

      Important Installation Note

      Installation availability, inclusions and add-ons vary by product type, service area, site access, existing services, selected options and property requirements.

      Some jobs may require additional work, upgrades or checks before installation can proceed. Final suitability may need to be confirmed based on site conditions, plumbing, electrical requirements, valves, drainage, access and compliance requirements.

      Supply-only orders do not include installation, old unit removal, disposal, valve kits, electrical work, plumbing alterations or compliance upgrades unless these are clearly selected or included in your order.

      Fast Delivery and Install-Aligned Shipping

      Installed Today makes delivery simple, whether you are ordering supply-only or choosing an optional install package.

      Delivery Options

      Same Day Delivery

      Same day delivery may be available for selected hot water systems in Brisbane and Gold Coast metro areas when ordered before 8:00am.

      Availability depends on stock, courier capacity, delivery location, product type and safe transport conditions.

      Express Delivery

      Express delivery is available on selected products and locations, with an estimated delivery timeframe of 1–4 business days.

      Standard Delivery

      Standard delivery is available on selected products, with an estimated delivery timeframe of 2–8 business days.

      Free Shipping with Installation

      When you select an eligible installation package, delivery is included as part of the supplied and installed order.

      Your product delivery will be organised to align with your selected installation period where possible, helping avoid separate courier timing, storage issues or delays between delivery and installation.

      Fast Metro Delivery

      Most hot water orders in metro areas are delivered quickly, with many arriving within 1 business day depending on stock, location, order time and courier availability.

      Weather and Transport Delays

      Hot water systems are large, heavy products and cannot always be transported safely during rain or unsafe handling conditions.

      Delivery timeframes may be affected if wet weather impacts loading, unloading, transport access or safe delivery conditions.

      Express Delivery Refund

      If your express delivery order takes longer than the estimated 1–4 business day express timeframe, your order will move to the standard 2–8 business day delivery timeframe and your express shipping charge will be refunded automatically.

      Order Tracking

      We will send your delivery details once your order has been dispatched or scheduled.

      For supplied and installed orders, delivery timing may be coordinated around your selected installation period rather than sent as a separate courier-only delivery.
