Underfloor Heating Extension Pack A - Solo 24

Extension Pack A covers up to 24 m² (as shown) at 200mm C-C (centre to centre).  This will produce approx. 100W/m² when used with a tiled floor finish.  By reducing the pipe spacings to 150mm C-C you will increase the floor output to approx. 140W/m², this will however reduce the maximum coverage area to 17m².

Pack A is supplied with a 2 way manifold and the area should be divided by laying 2 circuits of equal pipe length from the 120m coil of pipe supplied.  This ensures an equal flow rate through each circuit and thus an even spread of heat throughout the room.  In rooms with 1 or 2 exterior walls featuring a high percentage of glazing, the pipe spacings should be reduced in these areas to counteract the cold fall of air from the glazing.  (NOTE: This will reduce the achievable maximum coverage area).

The pipe layout below shows a typical installation at 200mm C-C.  Obviously the size and shape of any one particular installation may be different, but providing the pipe centres and the equal lengths for the 2 circuits are adhered to, the end result will be the same.

1. Use corrugated sleeving near the manifold to protect each pipe as it exits the screed.
   
   
2. Use the detailed plant and wiring diagrams.
   
   
3. Always use as much of the pipe supplied as possible.
   
   
4. If an anhydride pouring screed is used, the number of fixings should be doubled.  (contact Begetube for advice)
   
   
5. For pipe spacings of 150mm c-c, please ensure that a minimum radius of 100mm is maintained (see diagram below).
