This unit has it components all separated so there is assembly required . Once the fuel line is purged of air, the unit will fire up quickly. It takes about five minutes to spool up the burner and put out heat . It takes about 15 minutes for maximum heat output. I let it run for an hour in my uninsulated garage , the temp rose quickly to a comfortable temp. My plan is to have heater out and just pipe in the heat. I will have to see how that works. This will be supplemental heat in areas my natural gas heater doesn't reach, around my tool box and workbench. The heat output is hot enough to almost burn your hand at the nozzle it is cooler at 10 ft. The exhaust tube gets very hot, and there no detectable smoke, it appears to burn super clean and efficient. It did manage to take my car battery down in about 2 hours , so a charger needs to be on the battery.
The included wired panel work great as does the remote . I was able to use the remote outside and away from the unit and it worked perfect. The one thing im not sure on is when you set it to it lowest position , the fan speed ramps way down but the heat output seems hotter. maybe it get less over time . The fuel pump slow down so i assume it uses less fuel when at it lowest setting.
So far, this heater has far exceeds my expectations . As long as it dependable and last, i would say its a remarkable deal.
