We are planning to move the boat to the Baltic next season and spend some time around there and then Norway, then eventually to the British Isles. Good heat is way up on my list. We have a Webasto diesel forced air system, that (big surprise) isn't working. This seems like a much simpler supplement to the Webasto that would likely draw less electricity and be more likely to actually work when we needed it.

Thanks Jon. It's on the list. Defender has them for around $200.
