What s the matter with the toilet heater that is always cold when it is not turned on?

I think it's because the pipe of the heater is connected to the outside world, and the pipe of the heater and the exhaust is one, so if there is wind, the outside wind can be blown in through the pipe of the heater, so that the wind will blow in through the heater.

I'm also cold and don't know how to deal with it.

How should this situation be handled?

The heater in the bathroom turns 5 minutes before the hot air becomes cool, and it is still the case when it is turned off and turned on again, which may have the following reasons:

1. The temperature in the heater is too high; When the heater works for a period of time, due to poor ventilation or abnormal heating elements, the internal temperature is too high, and the internal temperature control will automatically jump off to cut off the power supply of the heating elements, causing the hot air to become cool after 5 minutes of the heater!

2. The temperature control in the heater is abnormal; The temperature control is too sensitive, when the heater works for 5 minutes, there is a slight heat, the temperature control jumps away to cut off the power supply of the heating element! Cause the heater to turn for 5 minutes, and the hot air will become a cool breeze!
