Features & Benefits Unit & Ceiling Valve Unit Specification

The loft mounted 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 3oC higher than outside, and as the loft mounted unit draws fresh air from the loft and delivers it into the property via the innovative diffuser, this results in a relative saving of around 150 Watts of heat energy per day in an average modern family home.

Designed to run continuously, the loft mounted unit dilutes, displaces and replaces moisture laden air with fresh filtered air, forcing contaminants out of the property through natural cracks and leakages. Indoor air is improved, eliminating condensation and mould growth, generating fresh filtered air throughout.
