As a result of heat absorption by parts of the water, since the combustion principle, the construction

line or the inner body creates a temperature and the heating results are similar to the previous

Deratures. which makes the water heater cooler and heavier.

From the above description of exemplary embodiments it can be seen that the flow of the heating gas in a water heater by heat absorption in addition to the use of a special combustion process can be improved, in which the body to be heated is evenly distributed over the flow is so that the removal of carbon dioxide and the supply of the air required for combustion can take place uniformly and a complete combustion and a high thermal efficiency guaranteed.

For this reason, hot water or steam of any temperature can be delivered quickly,

S so that this considerably reduces fuel consumption.

Also, is the water heater according to the invention very simply constructed, so that its manufacture is simple and its cleaning is without difficulty can be carried out.
