Difference between stove and fan heater
Before I get to the point, let me explain.
A stove does not have a fan, so heat is transmitted widely and close together. Fan heaters, however, have fans, so heat is transmitted narrowly and far.
Also, while stoves do not require an outlet, fan heaters do. Please select the product that best suits your environment.
Photosensors
Some products are equipped with a function that operates on low flame when no one is present for a certain period of time and automatically extinguishes the fire when no one is present for an extended period of time. (The time it takes for the fire to go into low flame operation and the time it takes for the fire to be extinguished varies depending on the manufacturer.)

safety device
The standstill safety device, incomplete combustion prevention device, overheat prevention device, safety device in case of power failure, gas shutoff device in case of tip-over, overcurrent protection device, and 3, 5, and 8-hour forget-to-turn-off timers were installed in all of the models I checked.
Product Comparison Chart
The first premise is that no one except Noritsu and Rinnai seems to manufacture gas fan heaters in Japan.
Since it greatly improves convenience and safety, our blog wanted to compare products with motion sensors. However, the motion sensors were only available on Noritsu products.
Prior to that, the only Rinnai products available are those with Plasmacluster or those that also have a built-in electric heater. The details are written in the following article, but the paper states that Plasmacluster/Nano-e had no sterilizing effect as a result of experiments. Therefore, Panasonic and Sharp products with these functions are omitted from the comparison.
Ozone is also dangerous to the human body due to its strong oxidizing power. It is also a cause of air pollution.
Based on the above, this blog believes that you should not buy products that claim plasmacluster or nano-e effects or air purification effects, and therefore recommends Noritsu, which remains.

I hope the above is helpful.
