How Much Does It Cost to Replace a Hot Water Cylinder NZ?

Hot water cylinder costs – Auckland

When we talk to a customer about installing or replacing a hot water cylinder in NZ, we usually find that they come to us after doing a bit of research. Often the factor that helps them decide what model or size of a hot water cylinder to use is the price.

It’s important to consider the upfront cost of the hot water cylinder and the value over its lifetime. If you paid the same price for two different products, but one lasted for a year, and the other lasted for five years, which would you think was more valuable?

Before you worry about the cost of a hot water cylinder, then consider how long they last and how infrequently you need to buy one.

How long should a hot water cylinder last? Should I repair or replace my hot water cylinder?

If you’re spending money on a new hot water cylinder, you’ll probably want an idea of how long it will last. How often should you need to buy a new hot water cylinder?

Most hot water cylinders come with a manufacturer’s warranty of 10 years.

If you look after it and have regular maintenance done, you’ll probably be able to get closer to 20 years of use from a hot water cylinder.

When we are called to look at a problem with a hot water cylinder that is less than 10 years old, we’ll always aim to repair it rather than replace it. Even a hot water cylinder that is between 10 and 15 years old should have a few more years of use left.

Once a hot water cylinder reaches the 15-year mark, however, we start to weigh the costs vs benefits of replacing it. Depending on how much hot water you use and the climate where your house is, a hot water cylinder older than 15 years old will probably start to show signs of wear and tear. You might notice your water starts to smell funny or is slightly discoloured. This is a sign that there is corrosion in the cylinder or its anode rod. With that in mind, you should be safe in estimating that you’ll have your new hot water cylinder for almost 20 years.

Once you factor that in, you might view the upfront price of a hot water cylinder as a great investment.

Are you replacing like-for-like or upgrading?

It’s worthwhile considering the different categories of hot water cylinders:

• low pressure hot water cylinders
• mains pressure hot water cylinders
• gas or electric hot water cylinders
• heat pump hot water cylinders

The experienced team at Regency Plumbing can repair, replace, install any of these types of hot water cylinders. We can give you some options and discuss with you the benefits of upgrading from low pressure to a mains pressure hot water system. We can also help if you decide it’s time to move your hot water cylinder from the cylinder cupboard to outside the house.

Other factors to include

There may be other costs to consider.

• Do you have an old hot water cylinder that needs to be disassembled, removed and disposed of?
• Are there tricky connection issues because of what we’re replacing or because of very old plumbing? 

At Regency Plumbing, we’ll give you a price for the entire job, including any additional costs for disassembly, removal, connection, etc. It’s our best practice to be as transparent about pricing as possible.
