Q-Blue Greywater Heat Recovery Systems
Energy efficiency that pays off
Integrate a solution into your project that significantly reduces energy consumption and lowers operating costs. The Showersave QB1-21XE system is a state-of-the-art vertical heat exchanger that recovers energy from warm wastewater, e.g., from the shower, and uses it to preheat cold water. This solution is ideal for residential buildings, hotels, dormitories, sports facilities, or industrial facilities.
Heat Recovery
Why choose the QB1 system?
Highest efficiency among all vertical WWHRS systems on the market.- Lowest pressure loss – user comfort without compromise.
- Quality certifications: KIWA Product Certificate, KIWA Water Mark, and German DVGW certificate.
- Safety: copper construction prevents the growth of Legionella bacteria.
- Sustainable choice: systems suitable for reuse or recycling.
- Reliability: many years of manufacturer experience eliminate initial product issues.

- Proven reliability: vertical heat exchangers have been successfully operating in Poland – the first installations have been in use since 2013 and continue to operate flawlessly, significantly reducing the costs of domestic hot water preparation.
Heat Recovery
How does Showersave QB1 work?
The QB1 system works based on the principle of heat recovery from wastewater. Warm water from the shower, before entering the sewage system, transfers its thermal energy through the walls of a copper flow pipe, heating the cold water entering the system.
Possible installation configurations (SAP compliant):
System A – heats the water going to the DHW tank and the cold water to the shower- System B – heats only the cold water to the shower
- System C – heats only the water going to the DHW tank (greatest savings)
