Figure 1b: Layout diagram
The indicative diagram in figure 1b only illustrates the feed pipes of the individual user modules. The heating plant inside
the zone controlled by the module must be realised by feeding the heating elements according to normal methods.
- Water temperature range in centralised plant:
- Maximum water pressure in centralised plant:
- Module feed flow rate (nominal):
- Maximum recommended speed of heat transfer fluid:
- Pressure drop in module:
Some purely indicative general sizing data is shown below:

(*) Volumetric heat load "F": 20 - 30 - 45 W/m
Height of volume to be heated = 3 m
Δt = internal and external temperature difference (internal T = 20°C, external T = - 5°C)
F1 = 20 W/m buildings with an excellent level of insulation
