Domestic Hot Water Cylinders

We design and manufacture high quality domestic copper and stainless steel hot water cylinders in New Zealand to meet New Zealand and Australia’s performance standards. All of our domestic hot water cylinders are easy to install and require minimal maintenance, designed to be both energy and cost efficient to ensure your investment stands the test of time.

Mains Pressure Hot Water Cylinders

Stainless steel mains hot water cylinders have become a popular choice because of the material’s unmatched strength and ability to withstand high pressure and water temperatures. They are lighter and can be more energy efficient than other available options.
