Literally zero thought went into the placement of components and its design. It's not rain proof, so you have to have it covered if you're going to use it in an outdoor environment. I wanted to use this to heat up a static caravan and whilst the heat output is pretty good, it's a pain in the backside to use. The heater is 12v which means either you have a 12v battery to power it or get a transformer convert to 240v and run a cable (better option if you can't put a PV on the battery to keep it charged). So you need to keep it covered, well under the caravan seems a great option, except the air intake, fuel filler cap and exhaust pipe are all in the wrong places to be able to do this 'out of the box'. You have to extend the silly little bit of exhaust pipe they give you or the intake and heater fan will draw in diesel fumes and pump them into the caravan. Useful!!! So I laid a scaffold pole on the ground and fed the exhaust into it to get the distance away I needed. Next the refueling, depending on how hot and how fast you have the fan will depend on frequency of refueling, but red/green/tractor diesel is fine to use, but you have to pull the unit out each time you need to refuel. So I connected a funnel and a couple of tubes to be able to do this without removing from under the caravan. Problem with this is that you can't see the fuel level, so often get overspill. Next is the NON Bluetooth model, which I mistakenly bought. Don't!!! Get the BT model so you can have the app to control it, otherwise you have to either listen to the floor to hear the voice commands it give, or go outside, but even if you do that you can't see the display because it's on the other side of the unit. Once you have done an A-Team job on setting it up the heater kicks out some serious heat. It's unlikely you'll want full blast it's that effective. So some bad design flaws that need some DIY work arounds, but it serves a purpose, you'll likely just need to make a few 'modifications' to it for be user friendly.
