Double-circuit gas boiler with electric ignition, designed for autonomous heat supply (providing the needs for hot water and heating) of premises up to 184 m2. Saunier Duval Themaclassic C25 is equipped with an open combustion chamber, which primarily distinguishes it from the similar model Themaclassic F25. The useful power of the model is 24.6 kW, the efficiency is at the level of 91.5%, the capacity of the DHW system is up to 12 L/min Δt=25°C. It is possible to work on natural or liquefied gas, for conversion the user will need to replace the nozzles and the gas valve. Additionally, an outside temperature sensor can be connected to the boiler.
