About Peter Cocks
Having been a Christchurch manufacturer for over 50 years, Peter Cocks drew attention from buyer and competitor ‘Rheem’ and has operated underneath that umbrella since 2016. Rheem and Peter Cocks together are committed to keeping the legacy of supreme quality going strong for customers all over New Zealand.
This impressive reputation grew as Peter Cocks refused to sink an inch below impeccable quality standards, promising a lasting and reliable product to heat water in homes, businesses, farms and other properties all over the country. Proudly Kiwi, Peter Cocks takes pride in supporting manufacturing in the Canterbury region!

Introducing Peter Cocks’ Hot Water Cylinders!
Attached directly to your mains water pressure, these hot water cylinders are reliable, delivering optimum water temperature and sustained performance all year round! Proudly cost-efficient, Peter Cocks hot water cylinders are built to last – with their stainless steel cylinder component guaranteed under a 10-year warranty – provided it was installed in accordance with all the relevant building codes and standards applicable to your building. Boasting an adjustable thermostat to control the temperature of your hot water, you never have to worry about scaldings every again!
Peter Cocks is known for its long-lasting quality, due to the strength of the barrels that they manufacture for their hot water cylinders. Corrugated barrels (swaged barrels) provide increased strength and far better resistance to negative/positive pressure.
The barrels can sustain high temperatures and not sustain damage to their cylinders, meaning you can go as hot as you like without wrecking your unit (within reason, of course – don’t start a fire in there!) Being a strong, more hardy barrel, these hot cylinders naturally last longer!
Using specifically designed stainless steel, the units are designed to hold water, which makes them less resistant to corrosion over time. Add all that to a futureproofed design, and you’ve got a market favourite! Additional ports were added to the cylinders to allow for future connection and compatibility options, Peter Cocks really wanted to go the extra mile to ensure customers didn’t have to replace their cylinders when technology inevitably changes down the line!
This hot water cylinder won’t be added to any scrap pile of waste any time soon, futureproofing environmental waste as well!
