HV PIV Loft
The HV PIV LOFT is a loft mounted ultra quiet, low energy, low maintenance, home ventilation unit. The unit is designed to help ventilate a home using the well-established Positive Input Ventilation (PIV) principle.
PIV units have been preventing and curing condensation dampness related problems in homes for decades. They are also used to control other indoor air pollutants and have even proven to be an effective means for reducing Radon gas in some properties.
OPERATION
External air is drawn into the loft by the HV PIV LOFT unit. Before it passes through the unit’s filter, the air increases in temperature as it utilises otherwise unused energy in the loft from solar gain and heat loss from the home. This increase can be significant, but is typically around 3°C warmer than outside air over a heating season. This energy gain is significantly more than the energy used by the unit’s motor. The tempered, filtered air is then supplied centrally to the home via the unit’s outlet duct and ceiling mounted supply air valve.
The HV PIV LOFT can be set up to operate at a single, adjustable fixed speed or switchable between two separate, adjustable speeds, via a control box provided with the unit.
