Hot Water Cylinder

Hot water cylinders play an important role in any property, and for the majority of New Zealand houses, this includes an electric hot water cylinder. However, did you know that there are various types of hot water cylinders available?

In this blog, we will explore the different types of hot water cylinders - outlined below in separate pressure types! So, without further ado, let’s jump right into it!

Low Pressure

These are often open vented (or unvented) systems that rely on a pressure-reducing valve system that reduces the pressure below mains pressure supply. It supplies low pressure hot water and high pressure cold water to plumbing fixtures. This is also known as an unequal pressure system as it doesn’t provide the same pressure for hot and cold water.

Low pressure cylinders are often the traditional form of hot water cylinders that can be found in older buildings across New Zealand. They have the following benefits:

  • Inexpensive installation and maintenance

  • Less valves required

  • Quiet

However, they also come with some disadvantages:

  • Low pressure supply

  • Vulnerable to fluctuations in pressure

  • Larger pipework might be required (for hot water)

Mains Pressure

In comparison, mains pressure cylinders provide hot and cold water to various outlets at the same pressure. Modern installations of hot water cylinders are more often than not, a mains pressure system. Although more expensive, they come with a number of advantages such as:

  • Fast hot water delivery

  • High pressure hot water

  • Pipe layout can be more flexible

  • Efficient water usage (if using water-efficient fixtures)

Meanwhile, there are also several drawbacks to consider with a mains pressure system:

  • Noisy

  • Energy and water consumption can be large

  • Expensive

  • May require more valves for better performance
