The Drimaster provides whole home ventilation using the Positive Input Ventilation principle. Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property.

The Drimaster units are fitted with an internal temperature sensor. This sensor continuously monitors the temperature in the loft, boosting the air volume when the loft temperature is above a set level (heat recovery mode).

If the loft temperature becomes excessive the unit will switch to standby mode (no airflow). Once installed, the airflow can be set to suit the house size and, if required, the way it responds to the temperature changes within.

Typical PIV Installation

Positive Input Ventilation (PIV) is the most effective ventilation solution for tackling condensation, damp and mould problems within a property.

Mechanical Vent Heat Recovery (MVHR)

A whole house mechanical ventilation (MVHR) system usually combines supply and extract ventilation in one system. Systems considered here incorporate a heat exchanger.

Typically, warm, moist air is extracted from ‘wet’ rooms via a system of ducting and is passed through a heat exchanger before being exhausted to outside. Fresh incoming air is preheated via the exchanger and ducted to the living room and other habitable rooms.

These systems can be effective at meeting part L of building regulations.

Mechanical Extract Ventilation (MEV)

A typical extract system to control all your homes odours, moisture and pollutants. aesthetically pleasing, most suited to current homes and refurbishment projects.
