Rinnai Hotflo 125L Electric 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.

A Simpler Way to Buy Hot Water, Filters, Pumps and Plumbing Products

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. That means you can choose the product, review the available options and order with more confidence, without the usual back and forth just to understand the starting price.

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

Supply Only or Optional Installation

Choose the product on its own, or add installation where available on selected products and in eligible service areas. This gives you the flexibility to order the way that suits you best.

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.

Product Details That Actually Help

Key specs, sizing details, warranty information, product features and suitability notes are shown clearly, making it easier to compare products properly before you buy.

Common Installation Add-Ons Available

Where relevant, you can add common installation extras such as valve kits, bases, access-related items, removal, electrical options or other site-specific upgrades before checkout.

Built Around Brisbane and Gold Coast Homes

Our product and installation options are selected with common Brisbane and Gold Coast homes in mind, including local water quality, access issues, plumbing layouts, replacement requirements and typical installation conditions.

Not sure which size, model or installation option is right? Installed Today gives you a clearer path to compare your options before you order.

Designed to Make Your Decision Easier

Installed Today is built for customers who want a faster, clearer and more convenient way to buy.

Instead of guessing what is included, waiting for basic pricing or trying to work out which extras may be needed, you can review the product, compare your options and move forward with confidence.

Choose supply only if you just need the product.

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

Add common extras before checkout if your job needs additional parts, removal, access support or site-specific options.

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.

For supply-only orders, you can select from available delivery options at checkout. For eligible orders with installation selected, shipping is included and coordinated to align with your selected installation period where possible.
