Radfan, a UK-based start-up, has won the inaugural EarthHack, an online crowdsourcing competition that asked competitors to reimagine existing technology for a more sustainable home and save 1 million tons of CO2 per annum by 2020.
The Radfan is a low power fan unit that attaches to any standard central heating radiator and redirects the warm air straight out into the room. This makes the room warmer and more comfortable as it stops the warm air collecting at the ceiling or escaping out of the window.
Testing has shown that the Radfan can increase the temperature at sofa height by up to 2 degrees C without having to turn the thermostat up. The Radfan costs about £2 per year to run and could save up to 20% on the average domestic heating bill by putting the warmth where the homeowner wants it.
The Radfan is in stock and available for purchase from ECO Arcade now: Radfan at ECO Arcade
