Why accessories matter
Accessories complete the install and improve day-to-day use. A recess box protects and conceals a continuous flow unit for a tidy façade. Pipe covers shield and tidy exposed connections. Controllers give you set temperatures at the tap and flexibility for different rooms. Sensors help maintain stable output and smarter control. With the right hot water system accessories you save install time, protect components, and get consistent hot water.
Recess boxes for a clean finish
Rinnai recess boxes are a popular choice for new builds and tidy upgrades. Models are sized to match common continuous flow capacities from 16 to 32 litres per minute, so the unit sits flush with the wall and hardware stays protected. The Rinnai Enviro 16–26L Recess Box and Rinnai Enviro 26–32L Recess Box are built for their respective output ranges and arrive ready for installer fit-off. For Rinnai Infinity models, pick from the Infinity B Recess Box – White or the Infinity Recess Lockable Box – White for extra security on exposed sites. Where coastal air or public access is a factor, the Rinnai Lockable 16–26L Galvanised Recess Box and the Dune colour variant add corrosion resistance and a neutral finish that blends with rendered walls.
A smart recess install protects the appliance from knocks, keeps pipework contained, and reduces visual clutter. It also helps service teams access valves and filters without disturbing cladding or landscaping.
Pipe covers that protect and tidy
Pipe covers do a simple job well. They protect insulation, union joints, and valves from weather and UV. They also make the wall look clean. Choose the Rinnai Infinity Pipe Cover – White, Infinity B Pipe Cover – White, or the Pipe Cover – Dune to match exteriors and other hardware. Good covers reduce debris build-up around unions and help extend the life of lagging on exposed hot lines.
Smart control for comfort and savings
If you want stable shower temperatures and easy adjustments, consider controls at the point of use. Rinnai Wired Controllers in Black or White give direct, reliable set-point control and suit family bathrooms and kitchens. For flexible installs and retrofits, Rinnai Wireless Controllers in Silver remove the need for new cable runs. Add the Rinnai Wireless Sensors in Black or White where remote temperature feedback improves comfort or where rooms sit far from the unit. Whole-home setups benefit from the Rinnai Home Control System Kit in Black or White, giving a consistent interface across rooms.
Controllers help you pick a single comfortable temperature, so you avoid mixing at the tap and reduce hot water wastage. They also make it easier for children and guests to use taps safely.
Matching accessories to your system
Continuous flow gas units gain the most from recess boxes, pipe covers, and room controllers. Storage systems benefit from valves, trays, and insulation. If you are pairing with Rinnai continuous flow, check model compatibility on each accessory page. The Enviro and Infinity families have dedicated recess boxes and pipe covers sized to the chassis and flue position. Where a lockable front is preferred, choose a lockable variant to help protect controls in shared access areas.
If you need a complete upgrade rather than just accessories, Renovation Kingdom also stocks electric hot water units. The Rinnai Efinity Electric Continuous Flow Hot Water Unit gives compact, on-demand hot water where gas is not available. For energy-efficient storage, Rinnai Enviroflo AR Series and GR Series Electric Heat Pump Hot Water Systems provide strong performance with lower input power than conventional elements. For straightforward replacements, Rinnai Hotflo Compact and Hotflo Electric Storage Hot Water Heater ranges cover common sizes used across Australian homes.
Planning your order
Think through the location first. If the unit sits on an external wall near a pathway or in view from the street, a recess box will tidy the wall and protect connections. Select the pipe cover that suits the unit family and your wall colour. If you want set-temperature showers without mixing at the tap, add wired controllers to bathrooms and the kitchen. If running cables is impractical, pick wireless controllers and sensors. Note any local compliance requirements for safe trays and drains on indoor installs and tempering valves for bathroom outlets.
Order accessories at the same time as the unit to save time on site. Your installer can arrive with a complete kit, fit everything in one visit, and commission the system without delays.
Installation notes
All hot water work must be carried out by licensed trades. Recess boxes mount in accordance with manufacturer spacing and clearance guidelines, with fixings suited to the wall substrate. Pipe covers attach after final pressure testing and lagging. Controllers follow wiring or pairing steps set out in the manual, with power supply and low-voltage runs handled by the installer. Wireless options need pairing and a simple test at the tap to confirm stable set temperature.
Maintenance and care
Keep vents and covers clear of leaves and dust. Wipe recess box doors and pipe covers with mild detergent as part of seasonal home maintenance. For controllers, check buttons and screens operate smoothly and update batteries in wireless units as required. Routine servicing of the appliance itself should include checks of filters, valves, and seals. Good accessories make this faster because pipework is accessible and protected.

Hot Water System Accessories FAQs
Which recess box fits my unit?
Match the recess box to both the brand family and the flow rating. For Rinnai continuous flow, the Enviro 16–26L box suits 16 to 26 L/min units, while the Enviro 26–32L box suits higher outputs. Infinity models use dedicated Infinity boxes. Check the product page for the exact model list.
Do I need a pipe cover if the unit is recessed?
A recess box tidies and protects the main body, but a pipe cover can still help shield exposed unions and lagging below the box. It gives a cleaner finish and extra protection in high-traffic or coastal areas.
Are wired controllers better than wireless?
Wired controllers offer a fixed, robust connection and are ideal for new builds or planned renovations. Wireless controllers are faster to install and suit retrofits where running cables is difficult. Performance is strong with both when installed as specified.
Can I add controllers to an existing gas hot water system?
In many cases yes, provided the appliance supports remote controls. Check the unit’s manual or product page, then select wired or wireless options that list your model as compatible.
What colour should I pick for boxes and covers?
White suits most fascias and keeps a clean look near windows and eaves. Dune blends with rendered and neutral walls. Galvanised lockable boxes add durability on exposed or coastal sites. The choice is practical and aesthetic, so match your wall and other fixtures.
Do accessories affect warranty or compliance?
Using approved accessories that match the unit model supports compliance and can simplify warranty claims. Always install to the manufacturer instructions and local regulations, and keep invoices and manuals for your records.
