The water heater is steam-and-water capacious horizontal

    Water heaters are made according to TU 36-1851-84.

    Primary heat carrier for water heaters is saturated steam.

    The maximum (excess) working vapor pressure and the heated water – 0,5 MPas (5 ^kgfs/cm2)

    For each type of the size of water heaters the certain surface of a coil providing heating of working volume of water from 5 ^{° C} to 75 ^{° C} within one hour at a working vapor pressure 0,5mpa (5 ^kgfs/cm2) is accepted

    Primary heat carrier (steam) moves in a coil, cold water comes to the lower part of the case of a water heater and forces out heated water through the branch pipe located in the top part of the case. Working capacity of a water heater is defined by the volume of the water which is above a coil.
