How to exhaust household floor heating
With the advent of winter, the frequency of use of household floor heating has gradually increased, but many users have reported that the floor heating system is not hot or is not hot locally.

The air in the floor heating pipes will hinder the normal circulation of hot water, causing the heating effect to decrease. Exhaust air is an important part of floor heating maintenance, which can effectively improve heating efficiency and extend the service life of the system.
| Problem phenomenon | Possible reasons |
|---|---|
| Floor heating is not hot locally | Air trapped in pipes |
| The system is noisy | Mixing of air and water |
