The DRIMASTER 5+5 PLUS provides whole home ventilation using the Positive Input Ventilation principle. This form of ventilation is becoming increasingly recognised as the best value approach to ventilating a home

Essentially, the concept is to introduce air to the home at a continuous low rate, encouraging movement of air from inside to outside.

A single unit situated in the loft space will normally be sufficient to continuously dilute, displace and replace the old contaminated air in the home with drier, tempered (by utilising otherwise unused heat in the loft space) and filtered air. The result is a significant contribution towards providing a healthy, condensation dampness free, energy efficient home.

With only one electrical connection and no trickle vents normally required, the installation costs for this type of system are generally less than for a conventional set of extract fans with trickle vents and the entire home benefits from the ventilation provided.

Good quality loft mounted units normally incorporate a heat recovery function to introduce more heat into the home when the loft is warm during the winter months. Heat recovery functions are normally either Fixed Temperature Heat Recovery which adjust the flow rate ofthe unit to suit the loft temperature; or Intelligent Heat Recovery which adjusts the flow rate to suit the loft temperature and the way the home is heated.

The latter type is particularly good in terms of energy efficiency. These systems are highly effective but dorequire proper application and installation for optimum performance. Units incorporating low watt motor technology (Low Energy Positive Input Ventilation Units) can provide a significantnett energy gain to the home.These units are therefore very energy efficient, even when compared to natural ventilation systems such as Passive Stack Ventilation.
