The days are gone when it was just a low pressure or high pressure cylinder, these day we have choice and lots of it. The question is which is best for you.

We ask Rinnai National sale manager Gavin Brown what he thinks the market is crying out for.

For an endless supply of hot water and to achieve the most savings on heating your hot water you can’t go past natural gas. The Rinnai INFINITY ® VT continuous flow gas hot water range delivers your hot water on demand only when you need it. If you’re lucky enough to be able to connect to natural gas the standard Rinnai VT gas hot water range can achieve savings of up to 60% on your running costs when compared to an electric hot water cylinder!

And if you’re not, LPG is a great alternative and still saves you up to 15% on your running costs.

If you’re not one of the lucky ones to reap those running cost savings from gas, the next best thing is the new Rinnai Smart Cylinder™ – easy to use and once installed it is an electric hot water solution that learns your hot water use habits and automatically adjusts when it heats hot water to save you money by not heating water 24/7 like a standard electric hot water cylinder. Incredibly energy efficient, the new Rinnai Smart Cylinder™ typically saves 10-15 percent on water heating costs* – leaving you more money to spend on the things you love.

Available in a range of sizes from 135L – 250L, you truly will find the perfect Rinnai Smart Cylinder™ to match you and your household’s needs. If you don’t want to invest in the future to save with the Rinnai Smart cylinder technology, the HJ Cooper by Rinnai Mains Pressure range of hot water cylinders are a good alternative.
