ok so I've gathered materials for my rmh and I'm going to start my build this week... my question is how far can my exhaust be pushed down? I plan on doing mine in my garage and have to repair my driveway anyway so i had thought to run my exhaust down to the end of my driveway and then bring it back up. my intent is to help my driveway stay clear of ice dams. I understand that if I go with a narrower exhaust it will move the air faster which may help with what I'm hoping to accomplish. I know that this is not a traditional build but I figured it may intrigue someone. driveway is about 30' long and drops about 8' in that stretch. my intent would be to push the exhaust that 30' right away and then climb back up the driveway. Los I'm planning on doing a copper line to help with my hot water in my house. any thoughts would be appreciated.
