- Zero-Maintenance Build: Stainless steel casing with internal silicone membrane. No moving parts.
- Limescale-Proof: Designed specifically to handle hard water environments without efficiency loss.
The Heau Valve
Pure physics in action. A patented, passive valve regulating all flows with zero electronics. Built in Belgium to last a lifetime.
- Patented Thermostatic Control: Automatically manages flow using precise thermal expansion and pressure balance.
- Built-in Protection: Integrated debris filters and check valves ensure flawless operation.
- Belgian Engineering: Precision manufacturing designed for long-term durability.
Smart Thermal Backup
Runs electricity-free during daily use. An ultra-low power 12V heat pad maintains comfort even after long inactivity.
- 100% Passive Operation: Recharges automatically via warm water flow whenever a tap is turned on.
- Holiday Recovery Mode: If left unused for >3 days, a 12V backup pad briefly reheats the unit to 60°C.
- Safe Connection: Includes an IP65 water-resistant connector with a standard 220V AC/DC adapter.
Support frame
Pre-assembled and ultra-flexible. Mounts horizontally or vertically in seconds. No extra hands required.
- Fully Pre-Mounted: Ships ready-to-install to drastically cut down labor time.
- Versatile Mounting: Installs horizontally, vertically, or directly onto standard toilet frames.
- Single-Handed Ergonomics: Lightweight structure engineered to be easily handled by a single installer.
Integrated Manifolds
Integrated hot & cold manifolds supporting simultaneous usage across multiple showers and taps without pressure loss.
- Multi-Outlet Capacity: Handles high demand across multiple outlets concurrently with ease.
- Universal Fitting: ½” Eurocone-compatible outlets (includes 16/2 connectors). Expandable up to 5+ ports.
- Installer-First Convenience: Premium ball valves integrated at every outlet for quick isolation.
Problem
Cold water in the pipes = cold shower
Solution
Heat stored in bathroom = instant hot water
What is Heau?
How?
Easy to integrate
Infinity above built-in toilet
Can be placed on top of the toilet mounting frame so that it is neatly concealed in the wall. It needs to remain accessible via a small hatch.
Infinity in the attic
The Infinity can be placed in the attic and from there the pipes go to the bathroom.
Infinity in floor below
The Infinity can be placed in the basement or on a lower floor horizontally against the ceiling
Infinity in the cabinet
The Infinity can be placed against the back wall of the bathroom cabinet, storage space is retained but less deep
Infinity in the bath
The Infinity can be concealed under the bath or on the head of the bath
Infinity in the storage room
The Infinity can be placed in the storage room or technical room close to the bathroom
Infinity in the suspended ceiling
The Infinity can be mounted in the suspended ceiling of your bathroom

FAQ
TECHNICAL
-
It’s enough when you’re handy. All our products are robust and are made for easy installation.
-
Yes. The instant hot water technology is an add-on that eliminates wait times and water waste. A primairy heat source like a boiler, heatpump, on-demand water heater,…
-
Heau products feature an easily accessible mesh filter to catch coarse debris. Additionally, the dynamic flexible membrane naturally sheds scale, while bottom-positioned outlets flush away all limescale particles with the flow, preventing buildup in the reservoir.
-
Max. 30 m of pipes (internal diameter 20mm) between boiler (or heat pump) and shower.
You can verify this by opening the hot water at 100%. If less than 10L of cold water comes out before it turns warm, you can enjoy the instant hot water technology. Not the case? Contact us for a tailored product.
The operating pressure should be between 2 and 6 bar.
-
Perform the "bucket test": turn the hot tap on fully and catch the water in a 10-liter bucket. Does the water get hot before the bucket overflows? If so, the standard technology is suitable. If the bucket overflows and the water is still cold, please contact us for a custom solution.
-
Yes, your safety is our top priority. To ensure safe showering conditions, we conducted extensive testing in collaboration with certified research facilities.
USAGE
-
Relax and enjoy! During the first days, the water in the Therm-eau reservoir will slowly cool down (approx. 5°C per 24h). Once the water temperature drops below 42°C, the heating element switches on to ensure you can enjoy your instant hot water upon return!
-
Absolutely. Thanks to its high-performance insulation, heat loss is minimal (approx. 5°C per 24 hours) during short absences. For longer periods of non-use, the system manages standby temperatures efficiently and runs an automatic legionella prevention cycle (heating to 60°C) to ensure your water remains 100% safe and ready for instant use upon your arrival.
-
Yes. When you choose a cold shower, the heau system simply remains inactive and does not release any stored energy. The hot water is preserved and ready for your next warm shower.
