This is the patio heater you need if you want to be warm while SITTING on your patio.   Having owned a traditional tall patio heater for years, I got tired of only my head being warm,  or needing to stand to feel any heat.  At a friends house one chilly day, they pulled out this heater.  It is near perfect.   It took some time to figure out how to hook it to the tank. 

 **You need to attach it reversed thread**

Once hooked up and lighted, the heat output was great.  The heat is directed at a sitting level.  This is the single most important thing if you want to extend the patio season AND relax.  This heater kept 5 people on a large  outdoor sectional comfortably warm on a 50 degree day.  

I took one star off just because it is not easy to assemble.  Dont let that deter you from purchasing it.
