Underfloor Heating Extension Packs:LARGER AREAS

Extension Pack B covers up to 40 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 28m². Pack B is supplied with a 3 way manifold and the area should be divided by laying 3 circuits of equal pipe length from the 200m 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).

Extension Packs for Underfloor Heating

The pipe layout above 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 3 circuits are adhered to, the end result will be the same.
