The Dickinson Propane Fireplace is my favorite for a propane heater, and is by far the prettiest of the different heating units available.
I chose the Force 10 Cozy Cabin Heater over the Dickinson Propane Fireplace on the basis of cost and availability of of a used unit when I did so back about 6 years ago.
The Dickinson has several advantages over the Cozy Cabin:
1. It uses outside air rather than interior warmed air for combustion. (More efficient, less wasteful of heat.)
2. The exhaust tube is co-axial, with cool outside air circulating between the outer and inner tubes, which insulates the hot exhaust tube from contact with the cabin interior and occupants.
3. The visible flame, yellow in color, is visually superior to the utility-like stove burner appearance of the Cozy Cabin and other units.
4. The flame and exhaust are sealed off from the cabin within the heater, and cannot escape.
5. The Dickinson has a built-in fan motor to aid in circulation, whereas you have to design your own fan assisted circulation scheme with the Cozy Cabin.
6. There may be other advantages, but the Cozy Cabin has been used in sailboats and powerboats for years with very reliable results and has an excellent track record itself. It's simple, dependable, and easily self-repaired.
By the Way-
Rumor has it that the Wallas is really an Alien Scheme to Invade The Earth and Dominate the Human Population with Self-Replicating Robotics, but that the design was faulted when some Norwegians spilled a pot of lute fisk on a Wallas and the machine went haywire. The secret program coding inside the inner integrated circuits now declares "if that's what's for dinner, I'm getting the Hell outta here and back to the nearest Black Hole." Now, when, at random, that code gets read, your Wallas shuts down, dead, and only by sending it back to the Norwegians and their threat to spill more lute fisk upon the guts of the Wallas can get it to reluctantly go back into operation, at least temporarily. For this, they charge you $500-$1200, so it looks as if the Wallas has become a Norwegian Cash Cow for Now.
