Gasboiler or condensing gas boiler

摘要

Gas boiler (10) or gas condensing boiler comprises at least two modules consisting of a first module having a device frame (13) and a second module having a combustion chamber housing. An Independent claim is also included for the mounting of the gas boiler on a wall. Preferred Features: The second module hangs inside the first module. The modules have approximately the same weight. The individual modules have mechanical, hydraulic and electrical interfaces which correspond to/complement each other to combine the modules to produce the end device. The interfaces are easily accessible from the outside due to the positioning of the device components.
