4INCH: for intelligent change!


4INCH is a Belgian company that firmly believes new technologies can be used for more than gadgets and luxury products. We believe they can make everyday life more pleasant for everyone and have a positive impact on the environment. Snugr our heating management system, is used by facility managers and building owners who want to increase the comfort in their buildings while cutting energy consumption. From a smartphone, tablet or computer anywhere in the world, users can easily instruct Snugr to adjust the temperature and create a heating schedule for each room. Our solution uses the Seebeck effect in order to harvest the required energy to remotely manage heaters, removing the need for wiring or batteries, making Snugr the ideal solution for energy-efficient renovation of existing buildings.
