For liquid or sand/cement screed floors For heat pumps or boilers
The Profi-screed staple system is installed onto rigid insulation, then covered with either traditional or liquid screed. Ideal for boilers and heat pumps as the heating water required is just 45 degrees.
Profi-screed staple system using 16mm PEX-AL-PEX or PE-RT pipe installed using staples & staple gun.
The Profi-screed staple system is compatible with low temperature heat sources, such as ground or air source heat pumps. The pipe spacing can be reduced or increased depending on the heat loss of the building and the water temperature being supplied by the heat source.
Installing this system:
Installation starts after the insulation layer has been fitted to the subfloor. A membrane (not supplied) is installed first if a liquid screed is to be used, containing the screed above the insulation. The edge isolation (supplied) is fitted around all perimeter walls, creating a thermal break between the floor and the outside walls.
Pipework is stapled directly into position following the CAD pipe layout diagram (provided). Flow pipes should be fitted with conduit (supplied) to reduce heat loss between manifold and the room to be heated.
Suitable Floor coverings:
Carpets with 1.5 tog or lower
Structural timber (18-25mm)
This system can be designed with the following average pipe spacing's.
Heat pumps with 35-45°C water available - supplied with a pre-assembled heat-pump manifold.
Boilers with over 45°C supply - supplied with a pre-assembled boiler manifold which has a mixing unit to reduce the water temperature
This system includes the following items:
Underfloor heating manifold - pre-assembled
Edge isolation with polythene DPM overlap
Thermostats for each room
System control box
CAD pipework drawing
Electrical wiring guide - first fix
Electrical wiring guide - second fix
