Looking for advice on a simple, economical and balanced ventilation product
Broan is marketing automatic make-up air dampers (models SMD6 or SMD8) that are synchronized to introduce fresh air into the HVAC’s return ductwork whenever a bathroom or kitchen range hood exhaust fan is operating. Premise is to balance or equalize the air pressure within the house. I’m assuming that’s better than using an “exhaust only” or “fresh air intake only” strategy to ventilate a tightly constructed house. Has anyone had any experience with these products. Only downside I can see is that one must use Broan ventilation products exclusively so that they can communicate with one another. Are there similar functioning systems available with more product flexibility (ex. Panasonic fans?). We live in climate is zone 5 in central OH … 5708 HDD’s and 797 CDD’s. I had read some articles on ventilation strategies on this site as was considering UltimateAir’s RecoupAerator H/ERV for our home that’s in the design stages, but I’m thinking there’s a considerable price difference between that product and Broan’s balanced solution. Any advice you can offer would be appreciated by this new member. Awesome site!
