It’s 1972. The world’s first video game, the Akari Pong, is out and the first LCD wrist-watch is cutting-edge. At the same time, a Welsh manufacturing company named Nuaire has developed the first anti-condensation unit in conjunction with the Northern Gas board. Positive Input Ventilation is born. Now fast-forward exactly 45 years, and Nuaire is celebrating the anniversary of its enduring Drimaster-Eco range; the latest update of its market-leading PIV range. The ‘blue elephant’ is still the UK’s most popular whole-house ventilation range, curing condensation dampness, removing radon and improving indoor air quality in over 1 million homes. Dri-Eco saves energy through a unique heater design; controls air quality with wireless sensors, and boasts unique hall-control thanks to a circular diffuser that houses the full system controls.
