Recycle & Money

Save Money by Recycling Hot Water

The Showerex is a revolutionary heat recovery system that will slash your hot water costs by recycling energy.

It takes the wasted heat from the hot water going down your drain and uses it to pre-heat the incoming cold water.

This clever process substantially reduces the amount of hot water you use, saving you money, energy, and the planet by reducing CO2 emissions.


The Showerex Energy Saver is simply installed in a shower waste pipe and transfers the heat from the waste "grey" water to the incoming mains cold water. This can represent a nominal saving of up to NZ $550* off your hot water usage every year.

*Nominal example: A family of four having an average shower using 10 l/min of water at 38°C for 10 minutes, once a day at $0.28 per kWh.

Global Experts

Vaportec Ltd has been producing and manufacturing heat exchangers globally for over 20 years. These heat exchangers are used in such diverse areas from heating swimming pools to cooling juice in wineries.

Cutting Edge Technology

We thrive on challenges to try to reduce energy usage. Our research shows that the most efficient and economical way to reduce energy consumption for showers, is to extract energy from the "grey" waste water.

The Benefits

Get more hot water for your dollar

The Showerex Energy Saver saves energy, saves money and helps save the environment.

Hot Water

Showerex can reduce your hot water usage by up to 48% every time you shower.

Even if you have a very low flow shower already, you can still save even more hot water with Showerex.

With a low-flow shower head using just 6L per minute, you're still using 32.8 litres of hot water in every 10 minute shower.

By fitting a Showerex 1400 vertically you'll use only 17.0 litres of hot water for the same 10 minute shower.

Same Shower, Big Savings

That 15.8 litres of hot water saved every time you shower adds up.

Every year that's over 23,000 litres of hot water saved for a family of 4.

YHA uses Showerex to Save

By using Showerex, the YHA is able to recover the heat from grey water and use this to pre-heat the incoming cold water for their showers. Thanks to Showerex, the grey wastewater and the incoming cold water never mix.

You can recycle hot water and save money at the same time

The YHA are recovering approximately 40 - 45% of the heat from the wastewater and saving power on water heating in the process. By installing a Showerex on your shower, you too can save.

You'll Enjoy A Better Shower

Increased Pressure

On low pressure systems, Showerex can actually give you a much better and more enjoyable shower while saving you money.

By reducing the amount of low pressure hot water you use, Showerex gives you a higher pressure and more enjoyable shower experience.

Enjoy Your Shower

On mains pressure systems, there is no pressure drop on flow rates up to 24 l/min, so you'll get the same great shower while saving money.

Our Planet

Save Energy, Reduce CO2

As we know, a reduction in energy consumption is a must.

We are trying to insulate and heat our homes in a more efficient way. We're trying to use greener forms of energy such as solar power and energy saving heat pumps, not only to save money but to provide a future for our children.

Even with these systems, our hot water consumption has increased and still increases today! We're taking more showers and for a lot longer!

Totally Recyclable

The patented Showerex Energy Saver is made using Watermark Certified copper tubing, this material is not only the most efficient but is totally recyclable.

Every Shower Needs Showerex

Wherever there is a shower there should be a Showerex.
