How do folks heat their multi's - Page 2

There is an older 37 ft FP cat here in Denmark that has been used as a liveaboard by a family. They plumbed in a hot water central heating system from a small oil fired boiler.

I just spoke to a guy on a liveaboard steel motorboat here, he has installed an extra internal "window" on all hatches etc.

He uses a plumbed hot water system as well, as the air based ones are don't offer good temperature control in the different parts of the boat, you can only have 1 control place. He uses a dutch built boiler, can't remember the name..

The Cruiseair heat pumps in my endeavourcat work well at the dock, but you have to run the genset on the hook. They work fairly well until the water temp gets below 5 C. Of course as the water gets colder they become less efficient. Below 4 C you are in danger of ice forming in the heat exchanger, so if water gets colder than that where you live they won't work for you. Water temps here in NC tend to bottom out at about 6, but on rare occasions they will get lower for short periods. I personally don't like to have sea cocks open when I'm away from the boat so I have a pair of forced air heaters from West Marine that I use at the dock to prvent stuff from freezing. They have a no freeze setting which turns them on when the temp gets below 38F. I'm thinking of adding a small hydronics unit to the engine cooling loop. I hate that when I'm motoring in the winter that I have to dump all that heat overboard without warming my cabin.
