      Underfloor Heating
      JDP offers a complete range of systems for Underfloor Heating. Offering a complete package
      design service through its partner suppliers, which ensures the product you install meets all of
      your heating needs.
      By determining key factors of the installation site, the heat requirements for each room, zones
      are calculated and drawings are produced within a few working days, to allow the customer
      to comment on or amend details as required.
      After this, generally a period for considering the design, making comments and amendments
      is necessary to ensure all parties are confident before the package is made and delivered.

      • Gives a comfortable, even temperature
      • Low operating temperature makes it efficient
      • Less dust circulation
      • No restriction on interior design
      • Maximize internal floor space
      • Low maintenance

      Applications
      • Concrete floors
      • Screeded floors
      • Joisted floors
      • Battened timber floors

The system is designed and installed as a package to suit the specific application; however the




                                                                                                  Hot & Cold Water Systems
component parts will consist of a combination of the following:

Polybutelene Pipe
Tough yet extremely flexible, Polybutelene pipes have a pressure/temperature rating which
allows for continuous use at a temperature up to 95°C at 6 bar.

PEX Pipe
This cross linked Polyethylene, is designed for it’s exceptional strength pressure/temperature
rating which allows for continuous use at a temperature up to 95°C at 6 bar.

Distribution Manifolds
These central distribution points are where warm water is pumped from the boiler, into the
flow section of the manifold, around the various circuits of underfloor heating pipe, back into
the return section of the manifold and then back to the boiler.

Controls
A complete range of controls including, mixers, and pumps are supplied to suit the specific
application to provide the correct water temperature and flow around our UFH pipes. Room
thermostats are available in standard, electronic, remote sensing or floor sensing types.
