Product description
The HeatBloC
®
K33R is a premounted group of fittings for heating circuits. The pump can be
isolated by means of the ball valves and the mixing valve. The pump can thus be maintained
easily without draining the heating circuit system.
The HeatBloC
®
is designed such that it can be directly mounted onto a PAW distribution
manifold or a mounting plate. With transition connections, the HeatBloC
®
s can also be mounted
on modular distribution manifolds of other dimensions.
The HeatBloC
®
K33R is prepared for the operation as a supply group, such as for radiant panel
heating systems (e.g. radiant floor heating systems) - with constant flow temperature.
The mixing valve bypass is completely open so that the control range of the mixing valve can be
completely used even if the flow temperatures are low. In order to protect the connected radiant
panel heating system from overheating, a safety temperature limitation is included in the scope
of delivery.
The HeatBloC
®
K33R can be easily converted into a group for return flow temperature
maintenance. It can then be used with solid fuel boilers.
