Here is what we will do...
Clean the sub floor of all debris and add a damp proof membrane (DPM) if necessary.
Lay the floor insulation as neatly as possible taking care not to leave large gaps that could fill up with screed.
Fit the pipe fixing system to the insulation at 90 degrees to the direction that the pipe is going to lay.
Mount the manifold on a wall in a suitable location.
The underfloor heating pipe is fitted to the flow side of the manifold once the end of the pipe has been reamed.
The pipe needs to be laid out from the manifold to the furthest point of the room and returned back to the manifold in a ‘snake-like’ pattern.
Once the entire pipe has been installed the system should then be pressure tested with water. This will ensure that there are no leaks in the manifold, joints or pipes. The screed should be laid immediately after and pressure should be left on while this is being laid. A standard sand and cement screed should be laid in accordance with CP8204. It should be well mixed, well compacted, 75mm thick, and cured not dried.
The manifold flow and returns must be plumbed in after the boiler pump and before any other radiator or hot water zone valves, allowing the manifold a complete restricted flow and return from the boiler.
The underfloor heating comes with a programmable room thermostat so that the area can be controlled independently from any other room or hot water system.
The system should not be turned on until the screed has been allowed to cure as turning the heating on too early could damage the screed.
It does not include congestion charge, parking, any parts and materials.
Your underfloor heating installed and ready to use.
