Energy Efficiency

Powered by an Ultra Low Watt Brushless DC Motor, the EnviroVent Loft Mounted Unit utilises the latest technology to ensure minimum energy consumption and long term trouble free life, achieving up to 80% more efficiency than a traditional AC fan.

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^oC 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.

Warm air accumulates at ceiling level. This air can be up to 7ºC higher than the internal air at ground level. By introducing an almost imperceptible air supply into the dwelling from the loft space, the EnviroVent Loft Mounted Unit helps to redistribute heat around the home and thus reduce space heating costS.

During the heating season significant energy is lost incurred by opening windows to reduce humidity and condensation. By installing an EnviroVent 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
