19. Laddomat 21
With its construction, Laddomat 21 replaces the tra-
ditional connection composed of individual parts.
It is composed of a cast-iron body, thermoregula-
tory valve, pump, non-return flap valve, ball valves
and thermometers. When the water temperature
reaches 78 °C, the thermoregulatory valve opens
the water supply from the storage tank. The con-
nection with Laddomat 21 is considerably easier
and therefore, we recommend it. A spare thermo-
cartridge of 72 ° C is supplied with the Laddomat
21 device. It is used for boilers over 32 kW.

WARNING - Laddomat 21 is designed only for boilers with output up to 75 kW (inclu-
sive). We recommend using it only with boilers with output up to 50 kW (inclusive).
20. Thermoregulatory valve
Thermoregulatory valve type ESBE, TV 60 °C is used with
solid fuel boilers. When the boiler water temperature reaches
+ 60 °C , the thermoregulatory valve opens and fluid from
the building heating circuit (2) enters the boiler circuit ( 3 →
1). Inlets 1 and 3 always remain open. This ensures that the
minimum temperature of the water returning to the boiler
is maintained. If need be, a thermoregulatory valve set to a
higher temperature (E.g. 72°C) may be used.
Recommended sizes of the thermoregulatory valve TV 60°C.
For boilers: D14P, D21P, D25P .......................................................DN25, DN32
