Hi all.
I am exploring options for heating the boat while underway. Currently have a Webasto forced air diesel heater which works very well but it seems such a waste of energy with the engine not being utilised for heat in some sort of way.
The main engine is a Gardner 8LXB which runs very cool at 60C or 140F so not efficient to run the cooling fluid through a radiator really. So does anybody have any experience or thoughts on using the exhaust for a heat source?
It has a water cooled exhaust manifold but still lots of energy in the stainless steel dry stack. I think the exhaust is about 5 inch so fabricate a 6 inch section that could clip over a section say 1 meter length with a fan and insulated ducting to connect to the existing Webasto ductwork. I have been warned off heating water from the exhaust as it is so hot that eventually is will boil and cause headaches.
Any thoughts gratefully accepted
