What if the shower floor did more than just drain water...
Fundo Thermo operates entirely without power, batteries or cables. The system is designed to meet EN1717 requirements and supports high hygienic standards. The heat exchange process works in four simple steps:
- Fresh water is routed through the integrated heat exchanger - cold fresh water enters the recovery unit and flows through a dedicated, separate channel.
- Heat from shower wastewater is transferred - warm wastewater (approx. 40°C) from the shower passes through a separate channel alongside it. This allows heat to be transferred efficiently while keeping fresh water and wastewater fully separated at all times.
- Incoming fresh water is preheated - as heat is transferred, the fresh water (at approx. 10°C) is automatically preheated (to approx. 26°C) before it reaches the tap/shower mixer/thermostat.
- Less energy is needed to reach the desired shower temperature - because the incoming water is already warmer, the hot water system uses less energy to achieve the required shower temperature.
