The DRI-ECO-HEAT-HCS provides whole home ventilation using the Positive Input Ventilation principle. 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 DRI-ECO-HEAT-HCS fan unit includes an internal sensor to regulate the fan speed according to the temperature of the loft. The internal sensor is to increase airflow to the dwelling when the loft is warmer than the house. The units ‘Fixed Temperature Heat Recovery’ strategy shall be achieved via a sensor located in the unit and shall improve energy performance accordingly. This unit has all the controls for the fan in the ceiling vent allowing the user to control, programme and monitor the unit from inside the property.
A heater section incorporating a 400W heating element shall be fitted to the fan unit. It shall be electronically controlled so as to minimise energy use. A temperature sensor shall be fitted to the outlet of the heater and will control the output of the heater in an attempt to maintain the set point. The set point will be adjustable between 5˚C and 15˚C. Once installed, the airflow can be set to suit the house size and, if required, the way it responds to the temperature changes within.
