Showering may feel like a small daily act, but it’s the second most energy-intensive household activity after space heating, accounting for 85% of hot water usage.
In energy terms, it rivals laundry, lighting, cooking and electronics combined. Rather than allow heat to wash away, Zypho offers a smart, practical solution to reclaim that energy and improve household efficiency in the process.
Zypho is the flagship range of heat recovery systems from ZapCarbon, a UK-based technology provider committed to long-term environmental impact. Designed as easy-fit units for bathrooms, Zypho products work by recovering heat from outgoing shower water to pre-warm the cold water coming into the system.
The result is a simple, passive energy-saving process that requires no moving parts, power supply or complex machinery. Just install and start saving.
ZapCarbon, co-founded by Dr Andrew Smith (Technical Director) and Dale Holroyd (Commercial Director), has been developing climate-conscious solutions since 2006, working across public and private sectors. Zypho heat recovery sits alongside other innovations such as ZapIQ (a home energy and moisture monitoring system) and HealthyHomes, a retrofit-focused health and hygiene solution for landlords and tenants.
Zypho’s energy-saving promise is underpinned by a thermal capture rate of up to 82%. This means that households can enjoy shorter heat-up times, lower energy usage, and reduced fuel bills, all without any change to the comfort or performance of their shower.
Depending on model and usage, residents can expect to save between £150–£250 per year—a figure that makes a strong case for wider inclusion in SHDF (Social Housing Decarbonisation Fund) and eco-retrofit schemes.
For new builds, the vertical PiPe65 and PiPe75 models are designed to sit alongside the waste water pipe in two-storey homes, offering seamless integration into contemporary plumbing designs.
In retrofit contexts, the Slim50 and iZi30 horizontal units can be installed below shower trays or over-bath showers—a particularly useful option for single-storey homes or apartments. All units are compatible with standard plumbing fittings and come with a range of adaptors to ensure a tight fit.
Installation is straightforward for any qualified plumber, and once fitted, units require no maintenance. The system is passive and fully mechanical, making it as simple as it is effective. The energy performance benefits have also been compared to those of triple glazing—but achieved at a fraction of the cost and with no aesthetic compromise.
Zypho systems are gaining interest from housebuilders, developers, and landlords looking to improve EPC scores, reduce tenant fuel poverty, and meet evolving regulatory targets for home energy performance. And with a growing number of installers looking for quick-win efficiency gains, demand for reliable, proven WWHR systems continues to rise.
ZapCarbon hosts regular 30-minute webinars to introduce the benefits of Zypho and offer practical guidance on installation and specification.
Whether for large-scale housing projects or individual home upgrades, Zypho provides a quietly effective way to improve efficiency, futureproof homes, and help tackle the growing challenge of energy affordability in the UK.
