The LUNA 3 AVANT PLUS 240 FI boiler, produced by BAXI, represents a transitional example in the boiler sector. Originally a low-efficiency boiler, it has been transformed into a high-efficiency model with the introduction of a component: the recuperator.
The recuperator is a device that exploits the residual heat present in the exhaust gases, which would normally be dispersed into the environment, to further heat the incoming water. This process not only increases the energy efficiency of the boiler but also helps to reduce the environmental impact.
