Warm water from the boiler system is circulated
through continuous lengths of pipe embedded in
the floor, each room has its own circuit and all
circuits are connected to a distribution manifold.
As each room has its own circuit it is a simple
process to apply room temperature control, a thermostat
is fitted in the room and connected to an electrically
operated valve on the circuit serving that room.

Standard Control System
The normal method of controlling the water
temperature within a floorwarming system is by utilising
a manual 3 port mixer which gives a preset water
temperature of typically 50 ∞C. The Begetube
Standard control system uses a high flow rate 3 port
mixer but with some extra refinements. We utilise
pump fittings, which attaches the pump directly onto
the manifold and allows the use of a remote sensor
for the 3 port mixer. These refinements give superior
water temperature control, a quicker heat up time
and a neater manifold. Individual room control is
achieved by room thermostats; including a low voltage
remote sensor type for bathrooms. The thermostats
are connected to the manifold actuators via the wiring
centre with overall time and temperature control
provided by the clockstat.
Weather Compensated System
This system utilises the input from sensors to accurately adjust the flow temperature
to the floor heating. External, boiler and mixed flow sensors feed the controller
with the information required to make automatic adjustments to a four port
mixer valve, the valve mixes the flow and return to provide the correct heat
input to the building for any given situation. As the rate of heat loss from
a building is driven mainly by temperature difference, it follows that when
the external temperature rises then less heat is being lost from the building.
The compensator responds to this by lowering the flow temperature and in effect
allowing less heat into the building. This control system is completely automatic
and requires no input from the end user.
Regardless of the water temperature control system
chosen, the individual room controls will always
be specified the same. |
