CONFORTO Electric boiler – “AT” SERIES C

Our Conforto Electric Boiler is 100% efficient, reducing energy consumption and costs. It uses a probe in an immersion well that continuously transmits water temperature to an advanced microprocessor. The microprocessor reacts by powering only the needed elements to meet real-time demand. Steady and uniform heat is always maintained, and short cycles are eliminated. This innovative technology gives you maximum control over your energy consumption and delivers total comfort. Furthermore, the start-up elements are rotated, ensuring their cumulative run-time remains balanced, increasing their lifespan. Let our innovative technology work for you!
