Advice Needed - CFM Minimum Requirments

hreag22 | Nov 11, 2009 07:08 PM

Hey everyone. I need some advice (and have a pretty good idea of what type of feedback I am going to get), please...

My wife and I are in the process of building a new house. This is the 2nd house we have built together and are a little smarter so we went out and bought all our appliances prior to home design (so we are building our house around our appliances!)...

Well, we bought a 48" GE Monogram Oven/Range with four (4) burners, a griddle, and grill.

During the design process we questioned our builder if we needed to "upgrade 600 CFM" which is an upgrade. The builder (heating/ac/venting contractor) charges about $5Kmore if over 350 CFM (special duct work, etc).

Well, the house is being built, the budget/$ is gone, and we now have learned we have to buy the hood vent (a disconnect with us and the builder) for it is an appliance and it is not included. We can deal with this, however...

Here is the question; Let's say I was able to find a standard 48" range hood (we are having wood pannels on the outside of the range and my wife wants to keep the hood as small as possible) with 450 CFM max capacity would you do it? What is the downside? We are not "big cooks" but who knows, I suppose it is possible for us to have all four (4) burners in use as well as the griddle and grill but unlikely...

We live in the midwest, the house is a 2-story with about 1,600 foundation and 10-foot ceilings on the main level and a lot of space in the kitchen/great room and lots of windows/ventilation. I mention this for I have read other posts where people live in smaller dwellings and want as much CFM as possible and want to give you an idea of the space/natural ventilation.

I found this on electronic bay (it has the power of 450 CFM but is only rated at 300):

Am I crazy to buy it? GE Recommends at least 1200 CFM.
