Constructed from high grade duplex stainless steel and packed with features to benefit specifiers, installers and homeowners, making them exceptional value for money.
The 250 L and 300 L cylinders have the option of a second element making recovery times quicker and making it less likely you'll run out of water.
Install as a low pressure system then connect, without replacing your cylinder, to the luxury of mains pressure when you are ready.
Not suitable as a pool or spa heater.
Rinnai cylinders are manufactured to suit most NZ council water supplies. However some supplies can have a detrimental effect on the cylinder, its operation and life expectancy. Stainless steel cylinders are not suitable for bore or tank water.
Water supplies with a high level of calcium carbonate (hard water) can cause scaling on hot surfaces. We recommend a temperature of no more than 65 °C to minimise scale buildup. Scale reducing or water softening devices should be considered in hard water areas. The unit is not guaranteed against damage due to scaling.

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
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. Give us a call: 0800 RINNAI (0800 746 624)
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 contact a plumber/gas fitter who will be able to explain all the options to you.
