Getting a Hot Water Cylinder in NZ? Here’s Your 101

 

The hot water cylinder has become the most popular form of water heating in NZ. Here’s how they work, and why.

There are now many ways to have a heated water-flow in the home. In a nutshell, this method involves an insulated tank with a thermostat, and an electrical component to heat the liquid.

There are two types of hot water cylinder NZ that you can get, and they are:

 

  1. Unvented

The newer edition, involving an unvented tank. This system has really taken off since it was made legal in the UK in 1986. It involves a sealed heating tank directly connected to the cold mains.

Being connected to the pressure of the mains, they allow for a heated shower or bath, while keeping up a strong, continuous water-flow.

As they don’t require gravity to create a flow, this kind of hot water cylinder can be put anywhere in the NZ house.

 

  1. Vented

The more dated but more common of the two. The copper tanks are fed water from a ‘header tank’ located higher up in the house, with a vent pipe between this and the vented tank. Thus, gravity drives the heated flow around.

While the unvented tank gages pressure from the cold mains, the height of the tank about the tap sets your water-flow. This might be great for those showering on ground floor, while those on upper floors might be showering in a lighter stream. This is why electric pumps tend to be used with vented tanks.

Now we have an idea of how they work, you may be wondering, ‘why have a hot water cylinder in your NZ?’

 

Here’s a list of our top reasons!

 

  1. Cost effective

For a little bit more, you can get everything you need for a heated water-flow around the home – pump, valves, wiring, and of course, the tank. Get this all for a relatively low upfront cost.

On top of this, reduced heat loss and controlled night rates mean lower electricity bills for you.

 

  1. Reduced heat loss

As you can choose when to heat and re-heat as necessary, the hot water cylinder in your NZ home doesn’t always need a full tank of hot water. This means less heat loss through the tank’s insulated walls and on top this, less heat loss costs for you.

 

  1. Heated showers at your finger tips

Nothing beats a warm shower, especially when you come in from the winter cold. A hot water cylinder in your NZ home will mean heaps of heated water-flow, and great baths and showers all year round.

 

  1. Space efficient

Unvented tanks in particular can be placed anywhere around the home. They don’t need gravity to drive the flow, meaning no need for a header tank. This means you can put them wherever suits you best.

 

  1. Make it smart

These days, the thermostat controller can be hooked up to a smart controller device such as an iPad or HomePod. This makes it all the easier to adjust the temperature.

 

  1. Reduced heat loss

As you can choose when to heat and re-heat as necessary, the hot water cylinder in your NZ home doesn’t always need a full tank of hot water. This means less heat loss through the tank’s insulated walls and on top this, less heat loss costs for you.

 

  1. Connect to other heating systems

A hot water cylinder in the NZ home can be set up with additional connections that can be hooked up to solar power and heat pump systems.
