Finding a diesel unit that will work at anchor is not a big problem. I have the Newport wall mounted unit and it really puts out the heat.
- - But anything that burns fuel
(diesel or propane
, etc.) has to be vented to the outside which introduces problems of wind
reversing the "draft" in the chimney. In other words, they don't work underway - both from a requirement for a chimney and positive "draft" up the chimney - and - providing a level boat so that the burning diesel doesn't spill from its "cup."
- - That leaves you with the remote
mounted heaters - usually in an engine room - that use forced air and a diesel spray system for burning the fuel. Somehow you need to investigate how to get an exhaust
(chimney) system to outside the boat that is not affected by wind
and water spray while underway.
- - They can supply heated air to the cabin areas via ducts or heat water for modern hydronic heat radiators in each cabin area.
- - There are systems that use your fresh water cooling
system of the main engine to blow heat into the cabin - but - only when the engine is operating and producing significant heat.
- - By requesting a unit to work when underway, you have vastly complicated the problem but with sufficient research
and creativity there should be an answer.
