Outdated Product
A double-circuit boiler running on natural gas. It can be used to heat a room up to 186 m² and for hot water supply. The boiler has a closed combustion chamber (air for gas combustion is taken from outside, and combustion products are discharged there). The intelligent control system allows the equipment to change its power in the range from 8.7 kW to 23.2 kW, adapting to the current needs for hot water for heating and household needs. The coolant temperature in the heating circuit can be adjusted within the range from 35 °C to 80 °C, and in the DHW circuit - from 35 °C to 55 °C. The water heating capacity reaches 13.3 l/min. When operating at full capacity, the Italtherm SMART 25 F gas boiler consumes up to 2.64 m³ per hour. The device boasts a built-in Grundfos circulation pump, a copper...heat exchanger, a programmer and other high-quality parts and components typical of this manufacturer's equipment.
