Understanding how the
manifold & Pumpset work
Warm water is pumped from the heat source to the manifold
and pumpset assembly. If the system requires a top up of
heated water, the temperature control valve will allow more
heated water into the floor heating system via a one-way
valve or release cooled water back to the heat source for
re-heating.
Temperature input is easily increased or decreased by turning
the mixer valve control head. Clockwise closes the valve and
decreases the flow temperature, anti-clockwise opens the
valve and increases flow temperature (see page 6).
From the upper flow bar, warm water is distributed to each loop
of floor heating pipe via an adjustable flow gauge. The water
then returns via the return valves into the lower return bar.
When the room reaches the required temperature the room
thermostat sends a signal to the wiring centre to switch off
the circulating pump and close the actuators. This shuts
off the water supply to the loops of pipe in the floor and
therefore shuts off the heat supply to that zone.
Before assembly of the manifold, pumpset or pressure testing,
familiarise yourself with the various stages of assembly and
the relevant fact sheet. We also advise to watch the online
tutorials and technical support videos.
