Freestanding hydro wood boiler that heats up to 330 m².
Sphera 40: the power of wood, the intelligence of technology.
SPHERA 40 is the 48 kW hydro wood boiler designed to heat spaces up to 330 m². A freestanding solution built to turn the energy of wood into heat for the entire system, also integrating the option of producing domestic hot water in a single unit. Thanks to the E.S.T. system, the open expansion vessel is already built into the machine, while the boiler body works at zero pressure, simplifying the system layout.
Technology and control to use the energy of wood more efficiently. The electronic control unit manages how the boiler runs, while the draught regulator as standard automatically controls the primary air intake, helping to optimise combustion and consumption. The coils immersed in the water bath heat the system and, in the configuration provided, produce domestic hot water. With a heat input of 48 kW and an efficiency above 80%, SPHERA 40 delivers high performance and a complete solution for heating homes and spaces up to 330 m².
