F24H1/142 - CPC Classification

Classification description:

Water heaters, e.g. boilers, continuous-flow heaters or water-storage heaters; Continuous-flow heaters, i.e. heaters in which heat is generated only while the water is flowing, e.g. with direct contact of the water with the heating medium in which the water is kept separate from the heating medium by tubes, e.g. bent in serpentine form using electric energy supply
