I am in the process of updating the heating system in Pert 'Near a 37 Hershine. I have removed an old hydronic unit so I already have most of the components. I purchased a webasto 2010 used that was previously used on school buses in Alaska. It has been bench tested and ran great for a couple hours by sure marine in seattle. Couple of questions I have about converting it to a marine application.
First is the exhaust the old unit used a 1 inch flexible stainless tube. The webasto is very near the same size however it is recommended to use a rigid exhaust pipe wondering what you fellows have on your webasto unit. I have about 2 feet of ridged pipe from the heater but the remaining 4 feet with be new
My intake air on the old unit came from a 2 1/2 in flexible hose connected from the outside housing of the muffler. I am a little concerned about drawing air that close to where the exhaust exits the hull though its just combustion air. Secondly the intake on the webasto is about 3 1/2 in. will I have adequate air with a smaller hose. Thank in advance for any tips.
