Thoughts on These Make Up Air Systems?
Scott Gibson’s recent article https://www.greenbuildingadvisor.com/article/sizing-a-kitchen-exhaust-fan?source=W20004EN&tp=i-1NHD-BC-GYU-1aTZpa-1o-YbBQ-1c-rs3-o3kwf-l6r0YHDddH-1mCCKk&sourcekey=W20004EN&utm_campaign=green-building-advisor-prime_eletter&utm_source=eletter&utm_medium=eletter&utm_content=gba_prime_eletter&cid=63642&mid=1455130178 prompted me to renew my search for a proper make up system for a new house I’m building. Having researched it and read all the blog posts here including Martin’s https://www.greenbuildingadvisor.com/article/makeup-air-for-range-hoods has led me conclude that there are lots of moving pieces and not a great deal of manufacturer or building code help for this.
I plan on installing a 1400 rated vent hood with an exterior mounted blower motor and have looked at the Electro and Fantech make systems which are somewhat expensive (not prohibitively though). Broan also makes a fixed 8″ universal damper that is designed to work with Broan and Best Hoods (don’t plan to buy either hood)
I came across this economical system from CCB innovations, but I can’t find many reviews or feedback on it. https://ccbinnovations.com/ From appearances it looks like it should work well. I can match the size of the intake to the exhaust hood vent size (1o”). It’s designed to open when it senses flow in the vent hood and feeds air into the home’s cold air return. It can also be wired to start the furnace blower when the damper opens. So the make up air will pass through the furnace filter and be drawn in by the furnace blower and be conditioned by the home’s HVAC system if necessary.
Am I missing something? Seems like a simpler and cost effective solution compared to Electro of Fantech. I would have to design and place those systems with a separate intake vent in the house.
