Would you please tell me all about stove hoods.
I need a stove hood that is self-contained- is there
such a thing. In other words i can have no chimney
going out to the out side. the "hood" needs to be
directly over the stove; hugging the ceiling. Is there
such a thing?
Hoods that don't vent to the exterior of the home filter the air for
particulates and greases, then release the air back to the kitchen. These
can become fire hazards if the filter is not maintained/cleaned regularly.
All the ones I've seen skirt the stove area, and are not recessed in the
ceiling, or even with the ceiling. Which makes sense. These simply cycle
air within the kitchen, smells disperse in the home from cooking.
Vented hoods ventilate the air above the stove to the exterior of the home.
Which is good. The ducting to the exterior can become contaminated with
grease, which may become a fire hazard if a filter is not used. There is
also the concern for air makeup. The air vented from the home has to be
made up by introducing air from the exterior of the home. This introduced
air has to be heated or cooled as related to the exterior air temperature.
The filters used in unvented and vented hoods are not perfect. They all let
by some particulates and oils. Clean the filter on regular basis in hot
soapy water, rinse, and air dry before reinstalling. If the filter is not
snug fitting, some air is not filtered and causes problems down the line.
A vented range hood is now a code requirement. An exception exists that
allows a non-vented hood if a source of natural or mechanical ventilation is
otherwise provided. While I'm dead-set against it, just venting into the
attic (not code) is far better than no vent al all. (Be aware that it will
lower your ceiling insulation R-value and you must have a sufficient amount
of roof ventilation. Actually, it's really not all that hard to run a metal
vent to a roof hood.) You could also consider installing a non-venting hood
and a wall vent fan.
Check Menard's or Lowe's for non-vented hoods.
