Understanding how the
ESBE pump station works

Warm water is pumped from the heat source to the pump set
and manifold assembly. If the floor heating system requires
a top up of heated water, the mixing valve will allow more
heated water into the system via the inlet or release cooled
water back to the heat source via the outlet. From the flow
bar, warm water is distributed to each loop of pipe via the
adjustable flow gauges, returning via the valves into the
return bar.

Once the room to be heated reaches the required
temperature, the room thermostat sends a signal to switch
the pump off and close the actuators (if actuators are fitted).
This shuts off the water supply to the loops of pipe in the
floor and therefore shuts off the heat supply.

Before assembly of manifold or pressure test, familiarise
yourself with the way the manifold works and the various
stages of assembly.
