Chimney

Intro

  • The addition of chimneys, in all cases, reduces smoke pollution. It also increases combustion efficiency due to the chimney effect - more effectively pulling fresh air.
  • Chimney effect - height of the chimney is directly proportional to the pressure with which cold air gets sucked in.
  • It’ll make the smoke exit point higher, at least - which will make standing around comfortable.

Parameters

  • Suction power. Should suffice to change air 10 times per hour. This means 1000 m3/h for 353 sqft space (10ft high ceiling). 1186 m3/hr for 419 cuft space. 50 m3/hr for 1780 cuft.
    • Alternate guide: If kitchen is in separate room, 600 m3/h suffices. Else, good to go for 1200 m3/h.
  • Size: 60x60 (2-4 burners), 90cm (3-5 burners)
  • Autoclean: Better suction power and life.
    • Turbine blower forces air to move to chimney walls (oil goes thence to a collection bowl, which should be washed every month).
    • Thermal auto-clean - evaporate oil etc from insides of motor.
    • Position the motor so that oil goes out directly.
    • “Intelligent autoclean” periodically initiates autoclean cycle automatically.
  • Filters (with oil collection cup)
    • (Al) Mesh/ Casette filter. Pores need to be cleaned fortnightly.
    • Baffle Filter - Fe or Al beams/ baffles. Clean every 3/4 months.
    • Carbon / Charcoal filter. Deodorizes. Replace every 6 months.
  • Lights: LED.
  • Positioning: Wall mounted vs Island
  • Duct
    • Chimneys with ducts push air out of the house.
    • Ductless chimneys just pass the air to a charcoal filter and send the air back to the room.
  • Maintenance reminders: Buzzer, LED.

Exhaust pipes

  • Aluminium 6 inch pipe is common.

Core cutting

  • Cost 202103: depends on hole size and wall type. For single hole - 800 to 1k. For 3 holes: 700 per hole; for 4 - 650 per hole.

DIY with exhaust fan and pipe

  • Cardboard pipes and mounting - YT1

Hood installation

  • For gas stoves - 24 to 30 inches. For electric stoves - 21 to 30 inches.
