FAQs

In all Rinnai cylinder instructions, we mandate the use of a drip tray. This is because all cylinders have the potential to leak water and cause extensive damage.

Our instructions state:
The Rinnai warranty does not cover any consequential loss from leaks to the cylinder, so it’s important a suitably drained drip tray/catch pan is fitted as per AS/NZ 3500.4:2015 5.4 and G12/AS1 6.11.3.

Like-for-like replacements are a grey area as most installers will only replace the cylinder to the same configuration as the cylinder that is being replaced. In these instances, Rinnai still maintains that a drip tray should be fitted. This protects the homeowner and the building from any future problems should a leak occur. If a drip tray cannot be fitted, then look at other possible options such as:

• Locating the cylinder outside
• Using a continuous flow gas hot water heater
* As the world’s largest gas appliance manufacturer, Rinnai is widely regarded as the industry leader.
* Rinnai products are known throughout the world for their superior quality, safety, technology and sophisticated control systems, all factories are ISO 9001 and/or ISO 14001 certified.
* We have an established 40 year history in New Zealand.
* Rinnai are happy to advise that we now have an IANZ accredited Test Lab for MEPS testing on Hot Water Cylinders. The lab uses the latest in test equipment and can test all type of Hot Water Cylinders for MEPS heat loss testing.
We realise there's a lot of information out there. Water heating is important and it's better to spend the time up front deciding on what you need and what's important. We have an experienced customer service team that can walk you through the process. For those more complicated projects we also have a free specification service.

Installation costs are difficult to provide as every installation is different. Factors such as the length of pipe required , whether you have accessories fitted, how far away you live and choosing an internal or an external unit all influence the overall cost.

If you’re interested in a Rinnai hot water heating solution, we highly recommend you get an installer to come on site and provide a quote. Call our customer service team (0800 746 624) who can provide options for installers in your area.
