Make up air in tight house
We are in our new tightly built house in Maine and the heating season has started. Our house is sealed very well (AreoBarrier). We have an ERV ventilator (Panasonic FV-10VEC1). We have a range hood, 3 bathroom fans and a basement dryer that exhaust directly to the exterior.
We have noticed moisture on the interior panels of our wood front door- especially with colder outdoor temperatures when we are running the dryer or bathroom fans. We suspect the door panels are the weak link in our tight house and make up air drawn through the panels and is condensing on the inside and running down the door face.
What do we need to do (besides constantly mopping up the water running down the panels)? Do we need additional make up air sources? Is there an adjustment we should make to our ERV? Should we just release the multipoint lock on one of our other doors?
Is more information needed and air flow rates of fans and appliances?
Thanks for your help!
