Rated 5.0 out of 5.0 by Jack441 Good wall furnace for shop
I am using this in my 16 x 22 woodworking shop. It works very well and I bought it because it is direct vented and pretty easy to install. I do wish they made a slightly bigger model, like maybe 28K btu, because even though my shop is well insulated, it is built on a cement slab and I am in Wisconsin. So there are days when it takes this heater awhile to get up to my working temperature. I have been doing the initial heat up on cold days with another unvented 30K btu wall heater but I shut it off after the first warm up because the unvented ones leave too much gas exhaust smell. I then turn on this 18K btu vented unit and it keeps the shop warm all day.I think that if my cement slab floor was insulated, this one would handle it just fine and it's very easy to use. The fact that it runs without electricity is a bonus!

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.

Rated 2.0 out of 5.0 by Matt 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.
