Ventilation specialist


    This MVHR - WHHR100/60DC - is an efficient, slimline, low energy solution to controlling condensation and pollution. It provides low level continuous ventilation in a kitchen and up to six wet rooms, extracting moist, polluted air and replacing it with fresh, filtered air - recovering up to 64% of the heat from the outgoing flow. The user can to boost to maximum performance when required. The WHHR100/60DC is easily installed in the loft or roof void, or a cupboard The noise level and running costs are extremely low, and it is compliant with Parts L and F of the Building Regulations


  • SAP Q eligible (MVHR) residential whole house heat recovery unit for providing continuous ventilation in kitchen and up to 6 additional wet rooms
  • maximum airflow 94 l/sec
  • suitable for areas up to 260m2
  • up to 64% of heat recovered from stale air extracted from warm, moist rooms replacing it with fresh, filtered, warmed air to create a constant, comfortable, healthy environment
  • easy to install and maintain
  • for fitting into lofts, voids, false ceilings or cupboards
  • variable choice of low (trickle) speed and boost options for optimum setting at installation
  • the boost speed can be triggered by a switched live connection from a range of devices:
    • PIRFF (passive infra red)*
    • DRH240 (dynamic remote humidistat)*
    • THM (thermostat)*
    • a light switch (if more than one light switch is used, each one must be a double pole switch)
    • a remote switch/pull cord

(*PIRFF, DRH240 and THM may have integral over-run timer which controls the length of time that the fan will continue to operate at its boost speed after the boost has been switched off.)

  • low noise levels
  • low running costs
  • gives extra security by removing need to open windows
