Expecting restock
A wall-mounted gas boiler designed to heat domestic water and space up to 168 m². Being a condensing type of equipment, the Italtherm SMART 25 K boiler is highly efficient and has low gas consumption (no more than 2.64 m³/h in maximum power mode, corresponding to 21 kW). A wide range of burner flame modulation allows you to adjust the temperature of the coolant pumped by the circulation pump through the heating circuit in the range from 20 °C to 80 °C. The water temperature in the tap is adjusted in the range from 35 °C to 55 °C. The capacity of water heating for the hot water supply system reaches 15.2 l/min. The boiler heat exchanger is made of stainless steel - a durable material with high resistance to corrosion. The boiler has a programmer that allows you to flexibly adjust the equipm...ent operating modes by day and hour to optimize the heating and hot water supply systems.
