  • 1. To install the diffuser, cut out a section of the ceiling in the central position of your landing hallway. If possible, at least 1m away from a smoke alarm or CO2 monitor.
  • 2. In the loft cavity, mark the centre point between two joists, and drill a hole in the centre point.
  • 3. Using the diffuser template provided, line up the centre point, and mark out the section to be cut out of the ceiling.
  • 4. Cut out the section of ceiling ready for the diffuser, then fit the diffuser into the hole, and secure with the screws and plasterboard plugs provided.

Nuaire Drimaster Hung Loft Units

The unique DRI-ECO-HEAT-HC incorporates all of the functions of our DRI-ECO-LINK-HC unit but with the benefit of an integral heating element, located between the flexible duct and ceiling diffuser.

This heating component will temper the air which is distributed through the property via the ceiling diffuser, thus ensuring a comfortable living environment. This pioneering design sees the low watt heater (400w) react efficiently and effectively, guaranteeing an economically friendly product.

A temperature sensor on the outside of the unit monitors and controls the heater output to maintain the set point. The set point ranges from 5° to 15° and can be adjusted from the ceiling diffuser. If the temperature at the heater outlet is above the set point, the heater will not activate.


Please note, it is not possible to retro-fit a heater to other Drimaster Eco models.

The DRIMASTER-ECO range provides whole home ventilation using the Positive Input Ventilation principle, which introduces fresh filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.


It has become the UK’s most popular alternative method of low energy, cost-effective ventilation!

Invented by Nuaire and installed in thousands of dwellings each year, PIV can be a more cost-effective and simple to install ventilation solution, whilst still meeting building regulations.


The filtered air gently pressurises the home from inside out, forcing out the stale air.

Clean, fresh air is continuously drawn in through the lofts natural leakage points, passed through the filters and fed into the property via a central hallway diffuser.

The fan unit is also supplied with a fused spur. The 3 core mains cable from the power supply should be connected to a fixed wiring installation, via the isolator, via the spur, in accordance with current IEE wiring regulations.
