Quick and simple installation

Installation is faster, simpler and more cost-effective as the pressure release valve (PRV) and condensate connection are combined and long runs of additional piping are no longer required.

  • Fast and simple installation, saving time and expense
  • Built in safety device meaning no discharge pipe for DHW cylinder is required
  • No exterior PRV drip/stain as it feeds into a single cold water pipe
  • One less pipe to penetrate the building fabric
