Kingwei Oil Heater Test (VI)- What's the smoke temp
We first tested the smoke temperature on 30th April 2020. Four minutes the smoke temp rise from 31 to 260 Celsius. The rising speed is breakneck. Video link, https://youtu.be/471Fv0ecTGI
We took this second video on 22nd March 2021, in which the heater has an updated smoke construction. You can see that the smoke temp rises from 31 to only 140 celsius in the same four minutes, which means smoke has a slower pass speed, which leads to less heat loss. The heater's current heat efficiency is around 90%.
