Comfort Floor, example of pipe laying pattern

This is a simplified apartment, of only 4.5 x 6.5 metres to show the pipe laying principle. The blue plates are Rail Plates, the yellow plates are Corner Plates and the white areas are Adjustment Plates.

Case A has two similar cold walls, or both walls have windows. The piping is parallel to both walls for maximum heat emission. The circulation direction is chosen so that the warmest pipe is placed near the perimeter walls and the water cools down towards the warm partitions.

Case B has one clear main direction. For separate large rooms, i.e. separate long pipe circuits, the regulating valve is set manually so that the flow is in balance in all circuits.

In the above case, showing a typical detached house, a denser spacing is achieved at the perimeter walls, c/c 150mm in four rails where there are large windows and c/c 300mm is used elsewhere, including at the room with the small window in the upper corner. With very high windows, the dense spacing can be used in even more rails, with up to 6 or 8 rails to ensure that the air circulates upwards along the windows and so avoid draught along the floor.

In normal 2500mm high multi-storey flats (no heat loss up or downwards) with normal sized good quality windows the c/c 300 can be used in all areas. The heating need, except for the upmost level in multi-storey houses is small. The warmer pipes at the perimeter walls will ensure the right heat balance in the room.
