The Aladdin is my source of heat for the wintertime. I upgraded from a catalytic heater to the Aladdin. What I did not know first is that the catalytic heaters put off 750 BTUs. That's not terrible. However the Aladdin puts of between 2000 and 2500 BTUs -- I've read both numbers. It is significantly hotter.
Of course that means as a light source it will work great in the cold north and not so practical down south. Still, there were many times when I lit off my catalytic early in the morning to take off the damp chill of the boat. I believe the Aladdin will do that job better.
And a few years back I got cold -- could not get the boat warm one awful day at anchor while on the panhandle of Florida. I was told the water was unusually cold and theorize that is why I had the difficulty. I could and did get my cabin warm, but the galley area was too much for the catalytic heater. Frankly that was very disturbing.
Thankfully it was only one particularly frigid day. The only one I've spent at anchor that was seriously unpleasant in the galley. I do most of my living at my dinette in the galley.

What was odd is that I'd been in 15 degree weather over on the east coast in Georgia and could/did get the boat warm. The water temperature made the difference I suppose. Thank goodness for electric blankets, eh? The 12-volt kind are a real blessing.
I bought my Aladdin Genie III from
