Hot water

[ssobol]

I've been looking into the less expensive diesel heaters which I'm considering adding to my boat (although I'll probably put one in my garage first). In the process I've come across some YouTube videos that show how to use excess heat the thing produces.

In one case, the video shows a unit that puts a water jacket around the exhaust. This can be used by a heat exchanger for additional heat (with a tank and pump). While this can be used for the heat, it also could be used simply to heat water for a hot water supply.

In another video, there is a kit you can get that puts a heat exchanger inline with one of the air vents to use the warm air output to heat water.

Just some ideas for those people that have diesel heaters. Might be good on a 22.
