Main Features

High heat recovery efficiency – Recovers up to approximately 66 % of thermal energy from waste water, significantly reducing hot water energy demand

Fully passive operation – Works without electricity, pumps or moving components, ensuring silent operation and long-term reliability

Maintenance-free design – Durable construction eliminates the need for regular servicing or replacement parts

Flexible installation options – Vertical format with multiple available lengths allows easy integration into existing drainage systems

Wide application range – Suitable for single-family homes, apartment buildings, hotels, student housing and other residential or semi-commercial buildings

Sustainable and eco-friendly – Reduces fuel consumption, lowers CO₂ emissions and supports energy-efficient building standards

The ReQup-Plus QB1 is a high-performance passive waste water heat recovery unit designed to reuse thermal energy that would otherwise be lost through drainage. Installed vertically in the waste water pipe, it transfers heat from outgoing grey water — typically from showers or washbasins — to the incoming cold water supply. This preheating process reduces the workload of the water heater, resulting in lower energy consumption and improved overall efficiency.

Thanks to its compact and robust design, the ReQup-Plus QB1 is suitable for both new buildings and renovation projects. It operates entirely without electricity or moving parts, making it a reliable and sustainable solution for residential and light commercial applications aiming to reduce energy bills and environmental impact.
