This works fantastic in my van build the instructions suck but thank the gods for Youtube and Facebook. That being said I really do like this heater just remember that It only displays in Celsius not a big deal just thought I_ mention it. Also when the pump is on It makes a ticking noise which is normal for these .i was able to pretty much muffle that out by mounting it in the frame rail of the van and packing it with spray foam insulation , gonna be a pain to remove it but I_l cross that bridge when I come to it. Keep in mind that it doesn_ shut off to regulate the temperature just lowers the fan speed.
