PIV Loft Unit
PIV Loft unit is a home ventilation and condensation control unit for homes with a loft space. The unit gently ventilates the home from a central position on the landing in a house or the central hallway in a bungalow to transform a stagnant and stale atmosphere into a fresh, healthy and condensation free environment.
Energy Saving Benefits
Minimum Energy Consumption
Powered by an Ultra-Low Watt Brushless DC Motor, the PIV Loft Mounted Unit utilises the latest technology to ensure minimum energy consumption and long-term trouble-free life.
The unit takes maximum advantage of the benefits of solar gain from within the loft space – the natural accumulation of heat from the sun on bright days. Temperatures in the loft space are on average 3⁰C higher than outside, which results in a relative saving of 150 Watts per day in an average modern family home. This equates to approximately 10% of annual heating costs.
Warm air accumulates at ceiling level. This air can be up to 7⁰C higher than the internal air at ground level, by introducing an almost imperceptible air supply into the dwelling from the loft space, the PIV Loft Mounted Unit helps to redistribute heat around the home and thus reduce space heating costs.
With improved building features in our homes, such as cavity wall insulation, double glazingand draft proofing, ‘natural ventilation’ is prohibited. Stale air is trapped causing steaming windows, which ultimately leads to musty smells, dampness and mould growth. These mould spores are known as allergens and become airborne at the slightest disturbance. The microscopic spores are then inhaled and can trigger respiratory problems such as asthma, dust allergies and hayfever.
The PIV Loft Mounted Unit draws in fresh air into the dwelling from the outside and filters it before being delivered into the property. Moisture-laden air is diluted, displaced and replaced with clean, tempered and filtered air. This eliminates or reduces surface condensation, which causes mould growth, providing a significant improvement in the health of asthma sufferers and general indoor air quality.
No Need to Open Windows
To reduce humidity and condensation during the heating season, significant energy loss occurs by opening windows. By installing a PIV Loft Mounted Unit and providing fresh filtered air to the home humid air is displaced without opening windows and thus making significant savings to the occupier.
Low Life-Cycle Costs
With 5-year on-going maintenance free warranties and superior long life filters, the unit achieves the lowest life-cycle costing. All repairs, maintenance and component replacements are carried out simply and quickly by exchanging the filters and consumable items. The worn out components are then taken back to the factory to be recycled thus reducing the impact on landfill and saving millions of Euros in replacement costs.
Pre-Heater & Hours Run Meter
The integral pre-heater is designed to temper the incoming air during periods of low external temperatures. A sensor monitors incoming air and pulses the heater to ensure temperatures are held to pre-set minimums. Two independent safety cut-out devices shut down the heater in the event of fan failure. The heater facility is controlled independently from the fan by a conveniently positioned enable/disable switch. For monitoring of operational life and verification of usage, an integral Hours Run Meter is fitted.
