In-slab – Mixing kit / Pipe / Manifold 

 

Mixing Kit (reference 2) 

All In-Slab designs should incorporate a BCU 

Mixing kit to be fitted with “Hemp & Paste” 
Thermostat fitted on the mixing kit is recommended at maximum to be set at 50

°

This should be fitted after the secondary pump in the field yet as close as possible to the 
manifold servicing the In-Slab. 
 

Pipe 
The pipe used for the In-Slab circuit is recommended to be 16mm oxygen barrier pipe 
work. 
No more than 100m of pipe per circuit is recommended. 

This is broken down to a maximum of 50m on the flow and 50m return lines. 
No joins or bends to be fitted at any point in the circuit. 
This can be installed either tied to the mesh or to the insulated panel (Depending on the 

set up, 

refer to manufactures specification)
