Rinnai Tankless Water Heaters: A Comprehensive Guide

As anyone living in a temperate climate knows, having consistent access to hot water is essential for modern living. A crucial piece of this comfort lies within your home’s hot water system, and few names are as synonymous with these systems as Rinnai. In this article, we take a look at Rinnai tankless water heaters, exploring various models, their benefits, and key features.

Understand the Rinnai Brand

Why Choose Rinnai Tankless Water Heaters?

Rinnai tankless water heaters stand out for numerous reasons:

Endless Hot Water

Firstly, their expertise in tankless technology ensures continuous hot water supply, no matter your household needs.


Rinnai’s tankless water heaters help reduce energy usage, as they heat only the water needed in real-time, consequently lowering your utility bills.


Rinnai heaters are built to last, with a longer-than-average lifespan compared to traditional tank water heaters.

Space-Saving Design

These units are designed for compact living spaces, with their small, wall-mounted design saving valuable space compared to bulky traditional tank units.

Popular Rinnai Tankless Water Heater Models

Rinnai’s range of tankless water heaters includes several models, each catering to different needs and lifestyle. Some of the popular models are Rinnai Infinity 26, Rinnai Infinity 16, and Rinnai Infinity 32.

Rinnai Infinity 26 is ideal for two-bathroom houses, delivering 26 litres of hot water per minute. This model ensures an endless hot water supply for your entire household.

Rinnai Infinity 16 is perfect for small apartments with less demand for hot water. It’s capable of supplying 16 litres per minute, sufficient for a single-bathroom home.

Rinnai Infinity 32 is designed for larger properties with high demand, providing a whopping 32 litres of hot water per minute. This industry-leading performance ensures everyone in the house can access hot water without interruptions.

Installation of Rinnai Tankless Water Heaters

While some plumbing tasks might lend themselves to the DIY approach, Rinnai tankless water heater installations are not one of them. It’s a complex process that requires professional expertise. Certified professionals handle the process, ensuring all safety guidelines are followed diligently. 

Correct installation is crucial with gas tankless water heaters due to the need for specific exhaust and intake venting requirements. Furthermore, the location of the water heater can significantly impact its performance and efficiency – another reason why the installation process is best left to the pros.

Another critical factor to consider is the sizing of your Rinnai tankless water heater. It’s essential to pick the right size based on the number of bathrooms, appliances, and people in your home – factors that determine your hot water needs. 

Maintaining your Rinnai Tankless Water Heater

To ensure your Rinnai tankless water heater delivers peak performance, proper maintenance is necessary. Regular inspections and cleaning keep your system functioning efficiently. Manufacturers often suggest annual professional servicing to check for any issues in heating elements, inspect for leaks, and clear out any build-up inside the unit.

However, there are other routine maintenance tasks you can carry out yourself, like monitoring the system for any drops in performance or temperature changes. If you notice anything unusual, it’s best to schedule a professional inspection immediately to avoid causing further damage or reducing your system’s lifespan.
