Upgrade your hot water cylinder

Upgrading your hot water cylinder requires some thought. Fortunately, this guide will help you identify the important factors in your choice and what you need to consider. Now is a great time to try and upgrade the model you are using, especially if your current system does not meet your family’s hot water requirements and a like-for-like substitution will not work.

By replacing defective parts and regularly repairing the system, most problems can be solved. But to upgrade your home, a replacement is the way to go. If you find yourself often having several people in your house trying to shower first while the hot water is still there, it may be time to consider getting in touch with us.


There are several factors that can affect the use of hot water, the first being prolonged hot showers. Some showerheads can deliver up to 20 litres per minute. Frequent use of the dishwasher can result in excessive consumption of hot water, as the average dishwasher uses 10 to 12 litres of hot water per wash. A smaller cylinder may seem like a good idea, but choosing a larger capacity (if you have room) will be more beneficial in the long run.


There are newer models available on the market with more advanced technologies that allow the hot water cylinder to learn from the hot water usage patterns to heat the water more efficiently. As the leading water heater manufacturer in South Auckland, we predict this could lead to savings of up to 10% on your water heating bills.

Thinking of the future

You can also install a new hot water cylinder to replace the old one, making your hot water system ideal to face the future. There are a variety of systems on the market that can be connected to solar systems, heat pump water heaters and water heaters in the future. This will allow you to expand your hot water system in the future to increase energy efficiency.

With solar water heating, time is very important. If you think about solar energy in advance, then you can save a lot in the future by installing an already compatible system.

Water Pressure

When comparing pressure water heaters, if you find that the hot water pressure is a bit weak, you may have a low-pressure system. Perhaps now is the best time to switch to a high-voltage system. Upgrading to a networked pressurised hot water system means that the heating system can better handle multiple hot water needs simultaneously by reducing temperature fluctuations at the output. This means that you can use the hot water outlet in multiple showers or the kitchen and bathroom at the same time. When hot showers are a thing of the past, this improvement can have a huge impact on your entire family.
