ductless vent hoods...recent experience?

[Howie Oakes]

Hi All-

Having some last minute cold feet about using the ductless range hood/ HRV approach in the house I am building. Does anyone have any recent feedback from projects where this approach has had issues? I am 99% sure this is the route I am taking but it would be relativity straightforward (at this point...tick,tick) to vent this directly out the wall behind the stove. I would most likely bring in MUA, not because the hood/stove is huge or anything but because I only have ~50cfm of leakage. Both the exhaust and MUA would be on 6" dampers, interlocked with the hood (along with the hrv boost).

The range is induction and we do occasionally stir fry, cook bacon, fry wings, etc...mmmm...I think need to go grab some lunch...

thanks,

Howie

Howie,

We have used both the Broan and Honeywell dampers for MUA and SA.  They leak in the closed position about 15-20 CFM per damper (we tested 4",6" and 8")

What do you do now when you burn popcorn?  Open windows?  That is an easy way to vent when you need it.

Hi Howie,

Our induction cooktop with no direct vent hood is doing fine. I'm a horrible cook and burn things regularly. I've got 3 tubes venting the area by the kitchen and one nearby powder room that can run on boost to vent it out. It seems to work fine. The Burt pizza is gone even when we don't open windows.

For self preservation I should note that my wife is an excellent cook. I'm the poor one when fending for myself.

Albert.
