Ducting

Ducting is usually hidden, but can be visible too.

circular ducting

• takes up more height
• tighter seal
• less friction
• cheaper & faster to install
• not efficient for low pressure

rectangular ducting

• less high
• more asthetic
• worse seal
• Easily connects fan coil to main duct (what’s this??)
• louder
• more expensive

ducting is used in a MVHR system.
dMVHR avoid ducting, but might be more expensive and louder.

Cleaning¶

Air duct cleaning entails large negative pressure vacuums and roto brush equipment which is costly and too bulky for individual use. Hire a certified air duct cleaning company for this.

• ductless
  • ductless is the lack of ducting, avoiding ducting can make it easier to retrofit a system
• Mechanical Ventilation with Heat Recovery
  • A MVHR ventilates a house while reducing heat-loss, using countercurrent heat exchange.
    (For decentralized units see dMVHR)
    For energy (air humidity ) recovering, see energy recovering ventilation, ERVs are better.
• arteries are ducting
  • ducting transports air from A to B, just like arteries

  • can we avoid using ducting?
