Our wider story, featured in Housing Executive

Housing Executive speaks to ZapCarbon Technical Director Andrew Smith about energy efficiency in a new interview. Explore the thinking behind ZapCarbon’s approach to reducing energy use and the wider story behind the group that brings you Zypho shower heat recovery.
Hot water is a massive part of the average UK household’s energy bill. We spend around £600 per year on heating water for showers. By recovering heat from wastewater, Zypho improves shower efficiency by 30 – 82%.
A Zypho is easy to install underneath your bath or shower tray. Once in place, it passively recovers heat from every shower, day after day, year after year.
Less energy consumed = fewer CO2 emissions and more showers for “free”.
