Replacing your hot water system is an important decision, and for many New Zealand homeowners, the Rinnai Infinity range is a top choice for efficiency, reliability, and performance. If you’re considering replacing your Rinnai Infinity, understanding the costs involved can help you make an informed decision. In this guide, we’ll break down everything you need to know about the cost to replace a Rinnai Infinity in NZ and why it’s a worthwhile investment.


What Is a Rinnai Infinity?

The Rinnai Infinity is a continuous flow gas hot water system renowned for its ability to deliver hot water on demand. Unlike traditional storage tanks, Rinnai Infinity systems heat water as you need it, ensuring endless hot water while saving energy by avoiding heat loss in stored water.


Why Replace Your Rinnai Infinity?

Although Rinnai Infinity systems are built to last, there are several reasons you might need to replace your unit:

  1. Age and Wear: Most Rinnai systems last 10-15 years with proper maintenance. If your unit is nearing the end of its life, replacement may be more cost-effective than repairs.
  2. Efficiency Upgrade: Newer models are more energy-efficient, helping you reduce energy bills.
  3. Performance Issues: Inconsistent water temperature or reduced flow can signal the need for a replacement.

Factors That Affect the Cost of Replacing a Rinnai Infinity

The cost of replacing a Rinnai Infinity in NZ varies based on several factors:

1. Model Selection

Rinnai offers a range of Infinity models tailored to different household sizes and hot water needs. The cost of the unit itself typically ranges from $1,200 to $2,000, depending on the model’s capacity and features.

2. Installation Costs

Professional installation is essential to ensure the system operates safely and efficiently. Installation costs in NZ typically range from $1000 to $1,500, depending on the complexity of the job.

3. Gas Line and Plumbing Requirements

If modifications to your existing gas lines or plumbing are needed, this can increase the overall cost. For example, upgrading to a higher-capacity model might require additional work.

4. Location and Accessibility

The ease of accessing your current system can also affect the installation cost. Hard-to-reach areas or tight spaces may require more time and effort.


Average Total Cost to Replace a Rinnai Infinity in NZ
