The eCozy is designed for water radiators and heaters, and it consists of: eCozy Thermostats, an eCozy smartphone application (for iOS and Android) and the eCozy central unit. It offers features such as control of temperature, analytics and automation, connectivity to home area networks, response to utility pricing signals (for example, the time-of-use), and access to cloud-based services. The eCozy stands out emotionally amongst its market competitors due to its sleek (patented) design, highly intuitive usability and smart technological know-how (an award-winning heating algorithm). This design-driven ‘little thinker’ offers a much better user experience by eliminating the pain of setup, calibration and the maintenance of a digital thermostat. The eCozy central unit works as an access point, so that the entire heating unit can still be controlled with the eCozy application even without Internet access. Depending on environmental and usage factors, eCozy is able to create a mathematical model of the environment from repetitive manual settings, through which the temperature curve with each cycle gets more and more accurate, and as a result, reduces heating cost and increases energy saving. The eCozy learns from the user’s heating preferences and home properties, and provides a heating system that will suit everyone.
