Air Vents / Circulation
I did a search and didn't find what I was looking for...
I want to know/see what others have done to create fresh air ventilation for year-round use.
I know there are many thoughts, opinions and safety issues with the use of a buddy heater. I don't really have too many options on my budget, but want to overcome the safety part.
I decided to do some work in the van with my buddy heater last week to test efficiency and test for problems. I cracked the windows and got to work.
Works just fine to heat the space, but I created way too much condensation inside. I don't think it was dangerous due to its short usage time. I am not looking to heat the van overnight. I simply want to be able to run it for 15-20 min at night before bed and 15-20min in the morning to knock the edge off.
So, I need to circulate and draw in fresh air. How? A fan, yes I know. Do I need one for drawing in and one for pushing out? Where should they be placed?
