● GROHE Rapido Heat Recovery transforms waste heat into savings, reducing energy demand and carbon footprint of each shower by up to 48%
● The concealed shower system comes with a sleek design and supports up to three shower functions
● Fast and easy installation is prioritised thanks to integrated GROHE Rapido Shower Frame
Among the various sources of energy usage within a property, heating water accounts for a significant share1, particularly in the shower, where valuable energy goes straight down the drain. GROHE, a leading global brand for complete bathroom solutions and kitchen fittings, is addressing this concern and expanding its comprehensive shower portfolio with a new innovative, sustainable solution: GROHE Rapido Heat Recovery.
Developed with the Dutch startup Hamwells, experts in sustainable shower solutions, the concealed heat recovery shower system collects warm water from the drain and pumps it through a separate pipe surrounded by the cold-water supply, transferring some of its residual heat. The result? Both cost and energy saving, for a sustainable future. A four-person household can save up to €299 per year, reducing both energy costs and CO2 emissions by up to 48%.
The revolutionary design and significant energy savings don’t come at the cost of a luxury shower experience either. The GROHE Rapido Heat Recovery is compatible with GROHE thermostats such as SmartControl. It is available in mono or duo versions, supporting either a one- or two-spray head shower combined with a hand shower. The shower system also offers two different efficiency grades: a single-pipe heat exchanger version or the more efficient double-pipe heat exchanger option. The double-pipe version maximises efficiency by providing a larger contact surface for heat transfer.
Compared to other energy-saving upgrades, GROHE Rapido Heat Recovery serves as a more accessible and less invasive solution, helping to reduce CO₂ emissions while maintaining comfort and design integrity.
How the system works
1.Similarly to a traditional shower setup, cold water (around 10°C) enters the house and is heated to around 60°C.
2.The thermostat mixes the hot and cold water to a comfortable shower temperature of 38°C.
3.After the shower, water usually flows down the drain at approximately 34°C. However, with GROHE Rapido Heat Recovery shower system, the warm wastewater is pumped through a separated pipe surrounded by the cold-water supply, transferring some of its residual heat.
4.With the cold water now preheated, less hot water is needed to achieve the desired shower temperature, thus saving energy. The double-pipe version maximises efficiency by providing a larger contact surface for the wastewater to transfer its heat. Once the heat has been transferred, the wastewater is disposed of, and the shower can be enjoyed with peace-of-mind.
Efficient installation for maximum impact
GROHE Rapido Heat Recovery is based on the GROHE Rapido Shower Frame, enabling fast, easy, and safe installation of concealed shower systems for partners. Thanks to its pre-assembled components, installation time can be reduced by up to three hours. Requiring minimal installation effort and delivering maximum energy efficiency, it’s a low-impact upgrade that offers high-impact savings for years to come.
