Fig 8 Underfloor with multiple manifolds and DHW Schematic
Please note:
-
•
The 3 port diverter valve should be installed with the motor at any angle vertical to 30° above the
horizontal plane .
•
Additional circulation pumps with multiple manifolds maybe required depending on the system
design.
•
The above drawing is a schematic only and additional valves and fittings maybe required.
4.5.8 Towel Rails
Any towel rails installed in the system must be installed on the space heating distribution side. Ideally the
towel rails should be of the dual fuel type, i.e. they have an electric element within them. This enables
the towel rail to operate during periods when space heating is not required, i.e. the summer.
Kensa would recommend that any towel rails should either be installed as a separate dedicated primary
circuit with a separate zone valve and timer or can be used as an extension of the UFH circuit.
As the towel rails are now on a primary circuit, ferrous towel rails can be used which are considerably low-
er cost.
