Thermal drainage protection device
Tender specication:
The Oventrop thermal drainage protection device limits the water
temperature in boilers with integrated water heater or continuous-
ow water heater in closed hot water heating systems for different
fuels or solid fuels.
It complies with the DIN EN 14597 standard and can be used in
installations according to DIN EN 12828 regarding solid fuel
boilers with manual fuel supply and capacities of less than
100kW.
The installation of the thermal drainage protection device is
mandatory in systems in which the heat generator has to be
equipped with a water heater.

Function:
The Oventrop thermal drainage protection device is a pressure
balanced single-seated valve which opens with the temperature
rising. Control is carried out via two working elements which act
independently of each other. The thermal drainage protection
device can be vented manually.
The cold water entering the potable water heater provokes an
indirect cooling of the boiler and an exceedance of the max.
permissible temperature of 115 °C is avoided.
