    Comments about Mr. Heater® Big Buddy Indoor Heater (F274800):

    I waited over a week to give this review. I've had other Mr Heater propane Heaters and wanted to do an accurate comparison. I've had several that attach right to the propane tank. They throw much more heat, but aren't as safe and they tend not to last as long as they should. I actually use this to heat my house, approx. 1000 sq ft. It is 20 degrees out this morning and the majority of the house is at 68 degrees. My house is well insulated. I did but an extra carbon monoxide detector just to be sure. But neither that one, nor the 2 I already had went off. It uses radiant heat, which is nice, but seems to use more propane than the tank top heaters. It has a built in fan, which you can use batteries to run or buy the AC adapter. Either way, it doesn't throw a lot of air. I put a pedestal fan near it to spread the heat and that works great. A 20 lb propane tank lasts about 2 days on high. It's easy to hook up and get running. The tip over shut off is a great safety feature. Even after my new heat pump gets installed this Spring, this will be great to have for any type emergency. I would recommend buying this if you're looking for a safe, well built propane heater.
