In fact, for this problem, it is also a good answer. It can be literally understood as: the water flow speed of hot water in the heating pipe is slow, that is to say, the pressure difference between the water inlet pipe and the water outlet pipe of the floor heating is too small, so the return water of the floor heating is not hot. So how to solve this problem? Let's share:
How to do if the inlet pipe of the floor heating is hot and the outlet pipe is not hot
Check the water distributor and clean the filter screen. Every heating season, the rust and debris in the pipe will flow into the filter screen above the water distributor with the hot water, resulting in poor hot water circulation and small water pressure difference between the inlet and outlet, resulting in high inlet temperature and low return temperature of the floor heating in the home.
2. Exhaust to the floor heating. If there is gas in the floor heating pipe during heating, it will also lead to hot water inlet and not hot water return. The only way is to exhaust the pipe one by one in the water distributor.
3. To clean the floor heating, after the heating period, there will be some debris and scale in the pipe, which will adhere to the inner wall of the pipe after a long time, causing the floor heating pipe blockage. The solution is to ask professional personnel to clean.
4. Backwater pressure becomes smaller, if the pressure of the heating station is insufficient, it will also lead to the difference between the inlet and backwater pressure, resulting in the backwater is not hot. The solution: install a circulating pump or find a property to solve the problem.
Summary: it can be concluded that when the floor heating is used for the first time, the gas in the pipeline must be discharged, and the water inside must not be discharged. In addition, if the floor heating is used for a long time, the water separator must be replaced in advance.
