Types of hydronic underfloor heating
Hydronic slab heating
The heat from the water warms up the slab first and then radiates into the room above. It can take anything between 24 to 48 hours to realise any benefit depending on the thickness of the cover which acts as form of storage.
The ‘PEX’ Pipe used under the slab which transfers the heated water has been especially designed to prevent corrosion, and is secured prior to the pouring of the slab, to either the mesh or the reinforcing steel rods. To avoid loss of heat into the earth, insulation can be first installed before any of this work begins.
Hydronic screed heating
In-screed installations have a faster response time than in concrete slab installations, as it is closer to the floor surface. The same ‘PEX’ pipe is used but the method of securing it is by either pins attached to insulation foam or clipped to wire mesh. In addition the screed should be reinforced.
Hydronic heating directly under floor surface
The same ‘PEX” pipe is installed and allowances for insulation, pipe diameter and space taken into consideration. The pipe is secured by pins to insulation foam and where necessary notched batons which allow the pipe movement across the floor. The heating pipe is normally installed, before the floors are laid.
