Efficiently distributing chilled or low-temperature hot water through multi-story buildings to bring low carbon, affordable heat to residents.

Riser & Laterals


Risers and laterals are the horizontal and vertical pipework which carry either chilled or low-temperature hot water to customers in a multi-story building. This is a critical area of building services engineering as it can have a substantial impact on how efficient your energy solution is.

Key Considerations

Other Considerations

The design and installation of risers and laterals is a specialist area with many considerations, but a few other things clients should be mindful of are:

  • A suitable anchoring and expansion solution
  • Good design of the keep-warm systems via the HIU or other thermostatically controlled by-pass valve
  • It can often be cost effective to install the sprinkler system alongside the risers and laterals package
