Function
K32 – HeatBloC
®
with 3-way mixing valve
The flow temperature of the heating circuit is
controlled by the integrated mixing valve. Hot water
from the boiler and cold return water are mixed to
obtain the desired flow temperature of the heating
circuit.
The mixing valve is adjusted via an external controller
in combination with an electric actuator. The ball
valves allow a maintenance of the pump, of the
boiler / heat generator circuit as well as of the
consumer circuit without putting the entire installation
out of operation. Two thermometers display the
temperatures of the flow and the return and allow thus
a function control. The integrated check valve can be
opened, it avoids an unwanted circulation and can be
put out of operation to flush and fill the installation.
The insulation avoids that heat energy gets lost.
Application ranges:
•
Installations with several HeatBloC
®
s and
different flow temperatures (radiators and
radiant floor heating)
•
Installations with high fluctuations of the
flow temperature due to the heat generator
(solid fuel boilers, installations with power-heat
cogeneration)
