Step 1 Fit floor insulation on top of the oversite concrete. Make sure the floor insulation meets design/building regulations - typically 100mm in depth. Hints & Tips For extensions with greater heat loss, for example conservatories, you may need extra insulation or supplementary heating. Step 2 Apply edge strip round the perimeter of the room by taping it to the edge of the insulation membrane. This will accommodate any expansion that occurs within the screed when it heats up and cools down. Step 3 Secure the insulation joints with suitable foil tape. Step 4 Lay a polyethylene film over...

Installing the control unit Step 5 Using the wall bracket, fix the provided control unit to the wall using a hammer drill and 8mm masonry bit. The control unit should be fixed vertically with the mixing valve at either the top or the bottom, or horizontally with the electrical connection box uppermost. Plug the control unit into a suitable socket or wire to a fused spur (3amp fuse). Hints & Tips Always mount the control unit before laying pipework so that you can see clearly where to start and finish the pipe run. Fit the unit to a wall that can bear its weight and ensure adequate clearance...

Step 7 continued Make sure you maintain a consistent space of 200mm between the runs or 150mm for areas with high heat loss. For consistent spacing between runs use an appropriately sized spacer batten: e.g. 200mm space - 15mm pipe = 185mm spacer batten. Hints & Tips Always feed the pipework from the bottom of the coil. Handle the pipe gently, especially around bends, to prevent it from kinking. You may also need to use additional pipe clips on bends depending on the insulation you are fixing it to. Step 8 Cut the end of the pipe using Speedfit pipe cutters and fully insert the pipe insert...

Connecting to an existing heating system RETURN TO HEATING SYSTEM FLOW FROM HEATING SYSTEM RETURN FROM UFH PIPE CIRCUIT FLOW TO UFH PIPE CIRCUIT Step 10 The next step is to connect the existing heating supply to the control unit. There are different ways to achieve this so before you start decide on your preferred option. Option 1– control unit with direct control of the boiler Most central heating systems only have a hot water and central heating circuit. If the room with the underfloor heating is to be controlled independently, a third circuit is required. This is achieved by installing a...
