Figure 2: Floor layout
The indicative diagram in figure 2 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:
