Bests & Worsts Reviews from Amazon

I am very pleased with this heater. It has one or two quirks that I didn't expect (hence the 4.5 stars), but it puts out a terrific amount of heat, looks great and was a real bargain - Amazon is the best. What I didn't expect: * It's much larger than I expected. My impression based on the pictures I could find was that it was much smaller, but be prepared for a sizeable heater; * Contrary to the description, it doesn't have a digital temperature readout. I was a little annoyed at first, but then most temperature gauges don't work well anyway, and I heat the room to feel comfortable and not to a specific temperature, so this doesn't matter much to me now; * The thermostat works differently than I expected. The unit puts out a constant amount of heat, regardless of the setting, but the higher thermostat settings make the unit run until the room is hotter before it shuts off, which works fine; * I run my heater on a 40 lb. propane bottle. If you plan to run on a bottle, be prepared to buy a pressure regulator, hose and some fittings. Oddly, I couldn't find the right combination from Mr. Heater, but did buy the Red Dragon kit on Amazon, which works well. The only other fitting I needed was an adapter from 3/8" NPT to 3/8" flare, which was only $3 at the local hardware store; * I read reviews elsewhere that the internal fan is quiet. I like the fact that it has the fan, but find it a bit noisy to my taste. Since I have a vaulted ceiling and ceiling fans, I will rarely use the internal fan. It seems to work fine without it and runs almost silently, which is very nice. Overall, a real deal in my opinion that suits my needs almost perfectly. August 2011 Update: A few more observations after using the heater for a while: * we can smell the byproducts of combustion in the room when we use this heater. This is not surprising since the combustion gases are vented into the room. As a result, we use it sparingly (usually just to warm the room) since the smell can be unpleasant, and undoubtedly isn't good for your health if used extensively; * burning propane relases a fair bit of water vapour into the room, so we get condensation on the windows. Again, this is not a surprise; * this heater is certified by the Canadian Standards Association (CSA), which is one of the reasons I bought it. However, the CSA approval is only for use in the USA; these types of unvented heaters are not approved for use in Canada; * I did some reading online about unvented heaters (sadly after I bought this unit). Anyone interested in buying unvented heaters would do well to read up about the pros and cons before buying.
