Outdated Product
Double-circuit gas boiler with a rated power of 24.4 kW. The equipment can be used to heat houses with an area of up to 195 m² while simultaneously providing one or two points of water intake with hot water. Due to the condensation principle of operation, the Hotpoint-Ariston Clas One 24 boiler is economical (gas consumption in maximum power mode does not exceed 2.75 m³/h). A modulating burner and precise automation allow you to adjust the coolant temperature from a minimum of 20 °C (therefore, this boiler can be used in "warm floor" water heating systems) to 82 °C. The water temperature for DHW is regulated in the range from 36 °C to 60 °C. In addition to setting up the equipment using buttons and a display on the front panel, it is possible to control the boiler via Wi-Fi (the module is...purchased separately). The heat exchangers are made of stainless steel - a material that ensures the durability and reliability of the system. Safety is guaranteed by automatic control that switches off the equipment in the event of overheating, flame failure, lack of draft in the chimney, etc.
