"Tested Results" on Origo Alcohol Heater
As we've talked about it a great deal recently, thought I'd input what I ended up with for the weekend cruise. I originally considered the Zodi Hot Vent with 12vdc blower that resides outside the boat and has a four inch hose to blow only heated air into the vessel. Was relatively cheap but AFTER I ordered it, they called and said the Y2K doomsayers bought them out of stock and I could not get one until, oh, June!I think it was Rick that said he'd used the alcohol stove, so I bought two of the Origo models with non-pressurized tanks. We filled the tanks as designed (about a third full when tilted back to flat) and "fired that mother up". I used two units in an H31. Main hatch open four inches, solar fan cover open all the way. Boat temperature at lighting: 33 degrees. We timed how long it would take to get the boat to 68 degrees with units on "high": 22 minutes (I was impressed) Turned units down to "half". And started timer again. The book said that one unit with "full" (as designed) tank on "high" setting would last 7 hours. We found this highly inaccurate as we had the units on "half" and they went out somewhere between 3 and 4 am after only 4 - 5 hours of use. We all woke up about the same time (5am) in 40 degree cabin temperature (outside was 27). I miscalculated the amount of fuel required and ended up using the Origo stove alcohol supply to supply heat for the remainder of the morning. (Good thing I do most of my cooking with the Kenyon Butane stove.)The Origo is made well (as usual) and is simple to operate, fuel, extinguish, stow, etc. as usual. Provided excellent heat through radiating cover. Drawback: Uses a lot of fuel, but alcohol was only $4 per gallon and my boat has tons of room to stow lots of fuel.
