How to tune a Chinese diesel heater with no tools 2kW & 5kW

Hopefully, this explains how the Chinese diesel heaters can be tuned to perfection with no tools apart from your fingers. Out of the factory, they're set at a default value that gets them running. All of the ones I've tested have been terrible. If you follow these 'simple' guidelines, it'll run MUCH cleaner and MUCH more economical. I am not responsible for any damage caused by tuning your heater. You do this at your own risk! If you want a cheap but decent diesel heater, I found this one: https://ban.ggood.vip/15fsn I've done another video which covers the pump install and where you can buy it    • Chinese diesel heater - silent pump, how t...   A basic description of how to tune it with default fan speeds is: Turn the heater up to full and leave it to settle for a couple of minutes Reduce the maximum pump speed (0.1hz at a time) until it drops one bar on the display Increase the maximum pump speed (0.1hz at a time) until it shows all the bars Increase the maximum pump speed by 0.2hz to make sure it keeps the heat just over the top bar Turn the heater down to minimum and leave it to settle for a couple of minutes Reduce the minimum pump speed (0.1hz at a time) until it drops one bar on the display Increase the minimum pump speed (0.1hz at a time) until it shows all the bars Increase the minimum pump speed by 0.2hz to make sure it keeps the heat just over the top bar Repeat the above until it's all stable.
