Hot Water Cylinders

Hot water cylinders are a vital part of the hot water system in many New Zealand homes. They are usually located in a cupboard and are connected to the mains water supply.

Hot water cylinders come in a variety of shapes and sizes, but all have the same basic purpose – to store hot water so that it is available when needed.


How long should a hot water cylinder last?

A hot water cylinder should last for around 10-15 years, but this will depend on the quality of the cylinder and how well it is maintained.

What are the cylinders made of?

Historically. hot water cylinders have usually been made of stainless steel or copper.Stainless steel cylinders are more durable and have a longer lifespan, but they are also more expensive.

Copper cylinders are cheaper but they are more susceptible to corrosion and need to be replaced more often.

More recently hot water cylinders have a vitreous enamel lined cylinder. This is an organic finish that is fused to the metal cylinder and provides the best resistence to corrossion.

How do I choose a new or replacement hot water cylinder?

If you are thinking of replacing your hot water cylinder, there are a few things to consider.

1. The first thing to consider is the size of cylinder you need.

This will depend on the number of people in your household and your hot water usage.

A small cylinder is suitable for a household of one or two people with low hot water usage. A medium cylinder is suitable for a household of three or four people with medium hot water usage. A large cylinder is suitable for a household of five or more people with high hot water usage.

2. Should you get low pressure or mains pressure?

Older homes and homes in rural settings usually have low pressure systems. You know you have a low pressure cylinder when the person having a hot shower is affected by someone turning the tap on in the kitchen sink!

Increasingly, new homes and renovations are installing mains pressure hot water cylinders so that they can enjoy the higher water pressure, and the ability to have two showers operating at the same time.

3. The third thing to consider is the material the cylinder is made from. 

Stainless steel cylinders are more expensive but they last longer. Copper cylinders are cheaper but need to be replaced more often. Vitreous enamel offers the best protection from corrosion.

4. You should also consider the type of insulation the cylinder has. 

This is important as it will affect how much heat is lost from the cylinder and how much energy is required to keep the water hot.

5. Finally, make sure you consider the warranty that is offered with the cylinder.

Most cylinders come with a two or three-year warranty, but it is always best to check before you buy.
