Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Melksham premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
