Boat heating wish list

[Dave9111]

Interesting conversation.
Things to consider: Pex A is more flexible and about the same price. It doesn't use clamps. It works with quick connect fittings. Costs about the same as the other grades.

Instead of diesel, what about using kerosene/parafin? They must make wick heaters for boats? Good kero doesn't soot nearly as bad as diesel. Youll need a separate tank, but if you have space it might be worth it. Having a furnace fail when you really need it is bad news.
