Cheap chinese diesel air heaters just don’t exist. They would need to burn nearly a litre of oil every hour. Nearly all of them are specced as 0.51l/h at max output, so would not even burn 5kWh of fuel each hour, let alone deliver that heat as hot air. I expect 15% at least goes out of the exhaust, quite possibly 20%. I have two of these heaters - a large and a small one - and neither work to specification. But I anticipated that before purchase, so am not particularly disappointed with them. Basically the chinese lie and people actually believe their lies - perhaps that makes them more clever than a lot of their customers? Has your heater got choked up with deposits, and needed cleaning out, on 50% waste oil?
