Heat transmitter, typically boiler (1) transmits heat from first fluid, ie flue gas, to a second fluid, ie heat transmitting fluid or water. Boiler has internal surfaces (5) which need to be cleaned periodically and it has several closable openings (2) in the housing. Each opening has its own cleaning device (8) with which a cleaning means (9) filled with cleaning agent to clean the inner surfaces can be moved in and out of the respective opening. Heat transmittor has a cylindrical or box shape and the openings are embodied as connectors (4) and closed by lids mounted on them.
