Bought this upgraded commercial patio heater to replace an old Fire Sense heater that would no longer stay lite. Rather than replace the head for the second time I opted to buy this upgraded model and am sure glad I did. The quality is far superior to my old model and what really sold me on it was the ease of access to service the ignighter a Thermocoupler which are the most common parts that eventually fail on these heaters. My friend was so impressed with the quality he went out and purchased one for his deck.
