Well, to go one step further. My basement ceilings are a little over 9' I would say that the top tank is at roughly 8.5'. Just about where the ductwork is. LOLRBE17;2526246; said:Thanks. I appreciate it. I believe you on the height. We have basements in the NE that are 8' ceilings. I'm guessing the ducts in your basement is at 7'. The rack is tall, but it needs to be.
