Zypho engineers passive shower wastewater heat recovery systems, significantly reducing building energy consumption. Its core product efficiently transfers thermal energy from outgoing shower water, pre-heating the incoming cold mains supply to 33ºC. This process enhances energy efficiency by up to 75% without external power or complex infrastructure, making it a self-sufficient solution for thermal recovery.
Zypho functions as a product line developed by Aliaxis, a global leader in advanced fluid management. Its inception stems from Aliaxis’s insight into optimizing energy use in conventional showering, leading to a durable, low-maintenance thermal recovery system embodying sustainable innovation. This development aligns with Aliaxis’s broader mission to provide solutions for efficient water and energy access.
Residential and commercial buildings deploy Zypho systems for notable energy savings and reduced environmental impact. The company’s vision is to advance global sustainability through accessible heat recovery solutions, transforming daily water usage into significant energy conservation. Zypho aims to play a crucial role in lowering carbon footprints and promoting a more resource-efficient future.
Zypho is a Portuguese technology company specializing in drain water heat recovery systems that capture heat from shower wastewater to preheat incoming cold water, recycling up to 75% of the energy used for hot water production[1][3][4]. It serves residential, renovation, and commercial markets like hotels, addressing high energy consumption in showers by improving efficiency by 30-75% and supporting decarbonization in buildings[1][4][5]. Acquired by Aliaxis in 2023, Zypho has shown strong growth through new products like the Zypho Slim50 for smaller properties and a major win with Accor Hotel Group in France, positioning it for global scale via Aliaxis's network[1].
Zypho originated from EIDT, founded in 2009 in Portugal, which developed the ZYPHO heat recovery siphon—a compact unit installed under shower trays to recover waste heat and cut energy use by up to 40%[2][5]. The idea emerged from collaborations with partners like INEGI (an engineering research institute) and EDP (a major renewable energy operator and shareholder), focusing on sustainable energy efficiency[2][5]. Early traction built through market entry in Portugal, Spain, and France starting in 2020 with Aliaxis, leading to innovations like a horizontal unit in 2022 and the Slim50 in 2023; the 2023 Aliaxis acquisition provided Seedrs investors a 3.8x return and accelerated global expansion to over 10 countries[1][2][4].
Zypho rides the wave of building decarbonization and energy efficiency trends, capitalizing on EU mandates for heat recovery in new constructions and renovations amid rising energy costs and net-zero goals[1][5]. Its timing aligns with post-2020 sustainability pushes, where waste heat recovery addresses 20-30% of residential hot water energy loss, amplified by Aliaxis's scale for faster market penetration[1][4]. It influences the ecosystem by enabling circular energy use in services and homes, partnering with renewables giants like EDP, and proving viability through hotel deployments that could scale to commercial real estate[1][2][5].
Zypho is poised for explosive growth through Aliaxis's global distribution, targeting wider hotel chains, multifamily housing, and emerging markets beyond Europe. Trends like stricter energy regs and heat pump integrations will boost adoption, potentially evolving Zypho into a standard for green plumbing. As acquisition momentum builds—evident in 2023 wins—expect product expansions and influence in sustainable building tech to solidify its role in the energy transition.
