Great outdoor heater. We use this to heat a small outdoor covered deck and it works well.  We can enjoy coffee in the morning even with temperatures below 40 degrees.  It is so quiet and warms the area quickly.  The protective grill does not get hot to the touch so it is very safe to use even with our dog on the deck with us.  It will extend the time we can spend outdoors in the mornings and evenings.  I highly recommend this heater.
