Low and Medium Pressure Hot Water Cylinders
Peter Cocks has been market leaders in the field of manufacturing low pressure and medium pressure cylinders for over 50 years. We were the first manufacturer to achieve the high installation standards required for the A grade watermark, which is determined by a standard heat loss test and shows the thermal efficiency of a cylinder.
Cylinders from Peter Cocks Ltd are renowned for their durability and solid performance, so it pays to think of your long-term requirements when choosing your cylinder.
We have a size to suit every situation, ranging from 13 Litre Undersinks to 450 Litre models:
- Mains Pressure 500-800 kPa
- Medium Pressure 120 kPa
- Low Pressure 76 kPa
We manufacture Low/Medium pressure cylinders in both Light Weight Duplex Stainless Steel and High Grade Swaged Copper. Options are available for solar, wetback, heat pump, coil & more

Due to localised water conditions, Rheem New Zealand advise that any of its “Rheem” or “Peter Cocks” branded Low Pressure Copper hot water cylinders are not suitable for installation in the postcode areas 4120 and 4122 in the Hastings district. We confirm that these cylinders are outside of our Rheem Warranty water chemistry terms based upon recent testing and may result in subsequent pinhole corrosion. Despite not being covered under the Rheem warranty policy, on occasion, Rheem has voluntarily chosen to replace affected cylinders. This practice will cease for cylinders installed in the affected areas after 1 April 2022.
We would therefore recommend our Rheem vitreous enamel or alternately Rheem or Peter Cocks stainless steel cylinders for installation in these areas assuming localised conditions remain as per the recent water testing. Should you have any questions, please feel free to contact your local representative or Customer Services on 0800 657 336.
