What Zypho does
Zypho S.A. is a Portuguese designer, manufacturer, and seller of passive shower water heat recovery systems, headquartered in Vila Nova de Gaia with production in Montijo. The company was founded in 2009 and acquired by the Belgian water-management conglomerate Aliaxis in 2023. Its products — iZi (31% efficiency, copper), Slim (50% efficiency, 50mm profile), PiPeDW (65% efficiency, double-wall stainless steel), and PiPe (75% efficiency, single-wall stainless steel) — transfer heat from shower drain water (around 40°C) to incoming cold water (around 10°C), preheating it up to roughly 33°C before it reaches the mixer or water heater. The technology is entirely passive: no electricity, batteries, moving parts, or maintenance, and incorporates an anti-Legionella design with EN1717 backflow-safety and Passive House Institute certifications.
The company monetizes exclusively through one-time hardware sales via two channels: a direct e-commerce storefront (the Zypho Store) targeting individual consumers and small projects, and indirect distribution through plumbing trade professionals across Europe and Latin America. Its served customers span residential homeowners, hotel and hospitality operators (Premier Inn, Orbitur), commercial real estate (Rotterdam Market Hall), multi-family residential developers (Ridley House, Cityside), and government social-housing programs (São Paulo). Marketing is digital-first across a 12-language website, LinkedIn, YouTube, Twitter, Facebook, and email newsletters.
Cumulatively, the company reports more than 20,000 installations worldwide. It carries a registered Zypho® trademark and a RedDot Award, and operates with 11-50 employees under the strategic and financial umbrella of Aliaxis. Pricing is not publicly disclosed; B2B inquiries are routed through Aliaxis's Portuguese entity.

Zypho competitors and assessment
Company assessmentBroad incumbents
- Vaillant: Vaillant is a leading European heating and hot-water OEM offering boilers, heat pumps, and integrated water heating systems. Its established developer and installer channels across Europe make it a broad incumbent competing for the same specification dollar as Zypho's drain water heat recovery units.
- Geberit: Geberit is a European leader in sanitary and plumbing systems, including concealed cisterns, drainage, and water-saving technologies. As a broad incumbent with deep developer and installer relationships across Europe, it competes for specification share in efficiency-focused bathroom installations.
- Uponor: Uponor is a European plumbing and indoor climate solutions provider with hydronic heating and pre-heating systems that overlap with Zypho's heat recovery value proposition. Comparable specification channels among EU developers, social housing, and HVAC installers.
- Bosch Thermotechnology: Bosch Thermotechnology supplies residential and commercial hot-water and heating systems across Europe, including heat pump and condensing water heaters. A broad incumbent whose integrated offerings can be specified as alternatives to standalone shower heat recovery products like Zypho.
- Ideal Standard: Ideal Standard is a major European bathroom and sanitaryware brand serving residential, hospitality, and commercial segments. Comparable customer base among developers and hospitality operators, and an incumbent that could bundle or specify alternative efficiency solutions in lieu of Zypho's standalone heat recovery units.
- Rinnai: Rinnai is a global incumbent in water heating (tankless gas, electric, and heat pump water heaters) and offers integrated efficiency solutions that compete with Zypho for developer and homeowner specification. Overlapping customer base in residential and hospitality, with broader product portfolio.
Direct peers
- GFX (Showerguard): GFX/Showerguard historically produced shower drain heat recovery units for the UK and European residential markets, directly overlapping Zypho's product category and customer base. Comparable passive heat-exchanger technology targeted at new-build and social housing installations.
- EcoDrain: EcoDrain (Canada) manufactures drain water heat recovery systems that capture heat from shower drain water to preheat incoming cold water — a direct functional overlap with Zypho's shower heat recovery units. Comparable use cases in residential new construction and retrofits across North America.
- HeatSave (Aquatech): HeatSave (part of Aquatech) supplies drain water heat recovery units for European residential and commercial projects, directly competing with Zypho in the shower heat recovery segment. Similar passive heat exchanger architecture and EU building-certification positioning.
Others
- Aliaxis (parent): Aliaxis is Zypho's parent company and a global manufacturer of plastic and fluid-handling solutions for water and energy. Listed as an adjacent ecosystem participant because while Aliaxis does not directly compete in shower heat recovery, its broader water and clean-energy portfolio overlaps thematically and is the channel through which Zypho's B2B inquiries are routed.
