The PIV Loft Mounted Unit is a sophisticated whole house positive input ventilation and condensation control unit for homes with a loft space. The positive input ventilation unit gently circulates air around 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.

How important is Loft Ventilation?

As with other rooms in the house, condensation in the loft is caused by excess moisture in the air and a lack of adequate air ventilation. Roof vents have been covered or blocked by storage boxes or other items stockpiled in the loft.

Loft ventilation works alongside the insulation in your loft to maximise heat recovery whilst ventilating excess moisture to reduce condensation and ensure your property maintains the best air quality.

Key Features

  • Eliminates Condensation (No more wet walls or moisture on the inside of your windows.)
  • Benefits Asthma Sufferer (Improves air quality and reduces asthma triggers.)
  • Made In The UK (Supporting our local economy, lowering the carbon footprint.)
  • Prevents Mould (Ensures relative humidity remains constant, preventing mould growth.)
  • Reduce Radon Levels (Perfect for radon levels under 500 Bq m-3)
  • 5 Year Warranty (High quality products for peace of mind, saving time, money and hassle.)

Minimum Energy Consumption

Powered by an Ultra Low Watt Brushless DC Motor, the EnviroVent PIV Loft Mounted Unit utilises the latest technology to ensure minimum energy consumption and long term trouble free life.

Solar Gain

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 3°C higher than outside, which results in a relative saving of around 150 Watts per day in an average modern family home. This equates to approximately 10% of annual heating costs.

Heat Distribution

Warm air accumulates at ceiling level. This air can be up to 7°C 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.

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 replacement is 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 pounds in replacement costs.

Pre-Heater and 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 slowly 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.
