Great Little Heater
Great little heater for camping or even would be great for back up heat at home.

On low it heats up the tent 14x16 in a quick hurry (leave an air opening). I used rechargeable batteries for the blower and they seem to last quite soome time.

Reputation Justified
During the winter of 2014 when the temperature here in Western WV dropped to the single digits the burner assembly on my propane gas logs went bad and my heat pump/electric furnace was unable to keep our home at our thermostat set point of 68 deg. I went on line and did some research as to what our best options were as far as a safe dependable source of back up heat . After a couple of hours of reading the stats on numerous types of heaters and hundreds of consumer comments I decided on the Little Buddy and after purchasing one locally and firing it up (with ease) at my home the temperature (which had dropped by this time to the low 60s) started going back up! Yea! So this year even though I had the gas logs back up and running, and the temperature continued to drop, and the snow continued to pile up, I started thinking about what if the furnace quit working or we lost our electric for a period of time, I knew that our gas logs and our "Little Buddy" would not be able to keep our house warm and since my wife and I are retired and we are at home mostly all day every day I decided to purchase The Big Buddy heater and the 12 foot hose with the quick connect coupling and after starting it up and letting it heat my shop for a few hours, I am confident it, and Little Buddy and the gas logs will do a good job of keeping our home comfortable come what may.

Where do you safely discard the cylinder
This little heater is effective, but where do I safely discard the many empty cylinders. The trash dumpster sites, landfills and Lowes (seller) won't accept them
