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.

Big Savings Every Year

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.

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.

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.
