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.
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

Why Choose The Peter Cocks?
- Thicker, High Grade Copper – We use 0.7mm for our barrels and 0.9mm for our domes vs. the standard 0.5mm barrels and 0.7mm domes. This greater thickness significantly increases the life of the cylinder
- Swaged (corrugated) Barrels – The process that provides increased strength and far greater resistance to negative/positive pressure. This significantly increases the life of the cylinder
- High Grade Duplex Stainless Steel – Specifically designed for Water Storage. Lightweight, longer lasting, easy installation
- Certified to Approved NZ Standard (Copper cylinders)
- High Density Insulation – Lower power usage through better insulation. New generation CFC-free, non ozone depleting polyurethane
- Energy efficient – NZ MEPS Compliant
- Future Proofed – Additional ports allowing for future compatibility options
Peter Cocks does not compromise on quality – from the materials we use, to each stage in production – while still remaining price competitive! We do not follow the trend in quality-reducing, cost-cutting in the manufacturing process.
Our manufacturing process and smart design ensures that Peter Cocks is the best choice for a future proofed hot water cylinder you can reply on for durability and efficiency.
