How is it selected?
2.2.1 Getting started
A qualified heating engineer or a qualified mechanical services installer should select your radiant
underfloor heating system.
2.2.3 The heated floor
The slab will naturally dissipate heat through the media in an upward direction and provide uniform heat
transference. Downward heat into the subsoil is lost energy and can be minimised with the use of
appropriate under slab insulation.
The system is selected to provide the following conditions:
Flow temperature of the water
40 – 55
o
C
Surface temperature of slab
25 – 30
o
C
Room temperature
20 – 23
o
C
Heat output @ 200mm centres:
140 W/m

2.2.3 Concrete thickness
The thickness of the concrete slab will be determined by relevant building regulations and as such will be suitable
for floor coil heating. It is important that a uniform cover be maintained between the top of the pipe and slab surface
to ensure even floor temperature.
Minimum cover
30mm
Maximum cover
50mm
Minimum slab thickness
100mm
