Houston rarely gets really cold, so we sit outside nearly every evening on our open patio. We have had this about a year and it is just right to take the chill off two people sitting at a corner table. The large propane tank below the table only recently emptied after many months of use. It sometimes doesn't light with the piezo button, so I use a lighter. Piezo buttons don't last long down here (because of the humidity, I suspect), but this one usually works. I love this heater and would buy another one in a minute.
It's a nice little heater. I do mean little though. I would love to have a larger version of this type of heater for our back patio, but we (thankfully) have a roof for the patio. Roof is only about 7' tall, which is a no go for a big heater. A smaller version, like this, will have to do. And it does. It sits on a table top, of course, and you really need to be right beside the table to stay warm on a cool night. For that, it does the trick. It's nice down to about 50 degree weather (right next to it). Below that, and you really want a higher output heater. This heater works well and does what it should for an 11K BTU heater, but understand what you're getting. We actually have other higher BTU heater when it gets really cold, but this one serves it's purpose. Assembly wasn't too bad. The base weight is a bit of a pain, but just turn the whole thing upside down to attach. And if you plan on using it regularly or for more than a few hours at a time, get an adapter so that you can attach it to a 15-20 propane tank. They're cheap and well worth it for this heater. The 1 lb tanks don't last long.
Great product. Easy to assemble and gives off great heat. I bought a 20 lb. propane tank steel box and 4 ft type 1 hose for the propane. Drilled a a hole in the box to feed the hose straight up through the bottom of the lantern. So easy to do... and I'm 40 yr old woman!
