The heater works very well, other than the unbalanced fan that rubs and makes noise. I'm glad I spent a few hours on YouTube prior to installing it, or else I would have made many mistakes. Such as ensuring the unit is mounted with the glow plug on the top, and making sure the fuel pump is mounted at a correct angle and not horizontal or vertical. The instructions provided with the heater are in poorly translated Chinese, with many inaccuracies.But overall, I'm glad to have this unit in my campervan.
