How it works
The world’s first bathroom thermos.
Problem
Cold water in the pipes = cold shower
Solution
Heat stored in bathroom = instant hot water

How the system works
Thermos: The Heau Core
Thermal storage with extreme insulation technology, losing just 5°C over 24 hours. Maintenance-free, stainless steel with high quality silicone membrane.
- Proven Thermal Storage: High-end insulation technology (organ transport standard) limiting loss to just 5°C per day.
- 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.
