instant hot water
no more waiting before you take a shower or wash your hands
The advantages of Heau
Save water
A heau system reduces water usage by over 4160 litres per person annually – that’s 416 full buckets
Heau Infinity
The patented heau systems use passive technology, efficiently storing heat for up to 2 days. If a tap goes unused for a longer period, an integrated smart heating element kicks in to maintain the temperature.
Save energy
A heau shower saves over 119 kWh every year per person - equivalent to driving 790 km in an electric car*
Wellness
Enjoy a comfortable shower experience without compromising on efficiency. Every day instant hot water.
Easily concealed
The system can be discreetly integrated anywhere into the bathroom, keeping the installation clean and minimal.
Our technology
Think of it as a compact "bathroom thermos". It instantly delivers stored heat at startup and automatically recharges when water is flowing with heat from the boiler.
