This content does not replace the need for a qualified technical team or detailed design and installation guidance from manufacturers and specialist trades.

GROUNDWORKS

  • Is the HP suitably located, i.e. clear of restrictions with space for airflow, distance from boundaries, correct stand-off and with installation and maintenance access?

  • Is the HP base suitable for the location and site-specific ground conditions?


  • Has suitable drainage provision been allowed to deal with HP condensate?


  • Where the HP is not immediately adjacent to the property, has pre-insulated pipework been coordinated into the design i.e. trench depths and sweeping bends?


  • Consider security of HP unit i.e. casting a rebar loop or bracket into slab to provide a chain anchor point.


  • Has external trunking and insulation been specified to resist UV breakdown?


  • Is floor construction suitable for UFH with appropriate screed or floor system specification and coordinated levels?

  • Is the UFH pipework and manifold position accurately set out to allow ease of install, protection during build and access for maintenance?
