Smart thermostats are the perfect energy efficient thermostat and provide up to 15% of energy saving. Based on electronic technology, we developed high performance smart learning algorithms that can automatically adapt to the water heater configuration and end user hot water consumption habits. Now operational for more than 10 years, they are market-proof solutions.
Beyond the inner smart technology, we provide large range of user interface. From simple LED with keyboard, to full touch sensitive technology and wireless standard communication. These interface options make the solution flexible and user-friendly. The user interfaces are ready-to-use and can be customized for water heaters, but also gas boiler, solar water heaters, heat pumps and storage tanks, etc
Storage tank is the most universal usage of hot water. Most of the time, storage tanks are associated with potential multisource of heat generation. It can be oil, gas or biomass boilers, a separate heat pump and solar heater or water heaters. To guarantee a minimum of comfort it is often coupled with a backup heating element and equipped with a thermostat and a safety limiter.
Small capacity water heaters
Small capacity water heaters are challenging products. It requests a high frequency usage of hot water along the day, quick response for hot water availability. All of this in a compact and reliable water heater solution. Our offer can cover design services in order to have the best fitting thermostat, limiter and heating element solution for variety of compact water heater layout. For example, low to high heating element power with different shapes, capillary or rod thermostat for under sink and over sink, or vertical and horizontal cylinders.
