This picture
shows a typical underfloor heating system
designed to operate with a heat pump.
The pipes are ready for
the 80mm screed to be added.
The pipe spacing is on
average about 80mm (3"), and the
pipes are on weld-mesh, and kept within
the screed (i.e. not touching the insulation).
This results in very low water temperatures.
This increases the energy efficiency of
the heat pump significantly.
A tiled surface is much
better than a wood covering when a heat
pump is used.
This well insulated room
is about 4m x 4m and uses 2 x 100m parallel
loops of pipe.
The insulation thickness
below is 130mm of Kingspan. |
