DriMaster Ventilation

DrimasterHow does Drimaster work?

Drimaster is a positive input ventilation (PIV) unit that gently supplies tempered, filtered air into a home using otherwise unused heat within a roof.

The benefits of this are enormous:

  • First, it means that a significant proportion of external pollutants are prevented from entering the home.
  • Secondly, the use of the otherwise unused heat in the roof results in the ventilation unit providing a significant net energy gain to the home.
  • Thirdly, there is no better way to ventilate a home than from the inside out via a single, centrally located, supply air diffuser.

A good quality unit, fitted in your loft, will operate at an almost imperceptible noise level. You will hardly know its there. A properly designed and installed unit will ensure that old, contaminated, vapour laden air in your home is continuously diluted, displaced and replaced with good quality air. The result is improved indoor air quality and an environment in which condensation dampness cannot exist.

The installation of a low energy positive input ventilation unit will ensure the air in your home is completely replaced with better quality air around 20 times a day. This is the recommended rate to maintain good air quality.

Energy benefits
Your roof is an energy source. North-east to north-west facing tiles or slates absorb energy from the sun. Even the loft space itself is a substantial source of energy. During the heating season it will almost always be warmer than outside because of solar gain and conduction and convection losses from the home.

Positive input ventilation units use the tiles/slates and/or the loft space itself to pre-warm the incoming air before delivering it into the home. The input air enters your home at ceiling level, usually on your landing. This method recirculate the warm air that rises and collects there as well as reducing the heat loss to your loft.

The slight pressurisation effect created helps reduce infiltration of unheated air through the leakage points found in all homes, having a consequential energy benefit.

In simple terms, a good quality low energy positive input ventilation unit will provide a significantly greater amount of energy into the home than the energy it consumes in the form of electricity, providing a considerable net energy gain.
