Rated 2.0 out of 5 by 2 reviewers.
Rated 2.0 out of 5.0 by OK for a smaller area. Pros: Pretty basic and easy to use. Easy to install. Cons: The top heat deflector had come apart by the time I received it so I had to put tiny bolts in to hold it. The instructions and illustrations are very poorly written and drawn. The info about the heater had listed two different square footage that the heater would heat in two different places. December 24, 2013
Rated 2.0 out of 5.0 by Not recommended I bought the DV21L 5 years ago for my very large ice shack. I end up using a portable heater most of the time because the pilot is hard to light and the control knobs are very cheaply made and next to impossible to control. When it works, it works pretty good, but that is becoming more rare. The biggest warning I can give you is the prices that US Stove charges for parts. I currently need a $2 part priced at $8.01 on their website, which I would gladly pay. However, they want $19.40 for shipping, and there's no where else to get these parts and no other shipping options. This has happened to me 3 times in the last 2 years. You either need to pay a fortune for parts or find a way to repair it. It warms my shack, but the hassle isn't worth it. December 31, 2013
