Instant hot water without wasting water
Before you open the tap, you press the Wateeer button. The unit preheats the pipe with hot water and the water that is not yet at temperature is stored in an expansion vessel to be reused later as cold water, instead of losing it down the drain. Ideal for homes with long pipe runs or two or more bathrooms.
How does Wateeer work?
It manages the DHW return line so hot water arrives faster with a stable temperature, avoiding long purges and temperature swings.
Step 1 — Demand detected
When you open a tap, the system detects the demand and prepares the return line.
Step 2 — Return is activated
It moves the water up to the target temperature without long waiting times at distant outlets.
Step 3 — Stabilise and save
Fewer litres wasted and lower energy consumption thanks to a constant temperature.
Why three “e” in Wateeer?
The name Wateeer brings together the 3 E’s that define the system: Efficiency, Energy and Environmental. Three pillars to save water, reduce energy consumption and protect the environment.
E for Efficiency
Less water wasted and shorter waiting times. Wateeer optimizes DHW recirculation so hot water reaches every outlet faster.
E for Energy
It reduces unnecessary boiler or heater cycles, making better use of the energy you already pay for and smoothing operating peaks in the system.
E for Environmental
By saving both water and energy, it lowers the environmental impact of daily hot water use at home, combining comfort with a more sustainable approach.
