What to do if the heating circulation is not good

With the arrival of winter, the normal operation of the heating system has become the focus of many families. However, poor heating circulation is a common problem, resulting in uneven indoor temperatures and increased energy consumption. This article will analyze for you the causes and solutions of poor heating circulation, and provide hot topics and hot content on the Internet in the past 10 days to help you better deal with this problem.

1. Common causes of poor heating circulation

What to do if the heating circulation is not good

Poor heating circulation may be caused by a variety of factors. The following are common causes and corresponding solutions:

ReasonSolution
There is air in the pipeExhaust air through the exhaust valve to ensure there is no air blockage in the pipeline
Water pump power is insufficientCheck whether the water pump is working properly and replace it with a more powerful one if necessary
clogged pipesClean pipes or replace clogged pipe sections
Improper installation of radiatorRe-adjust the position of the radiator to ensure the correct tilt angle
Insufficient system pressureSupplement system pressure to normal range (usually 1-2bar)

3. Detailed solutions to heating circulation problems

1.Exhaust treatment

Air in your heating system is a common cause of poor circulation. Each radiator is equipped with an exhaust valve. Find the radiator at the highest point and use a screwdriver to gently open the exhaust valve until water flows out. Then close it. Pay attention to preparing water containers to avoid getting the ground wet.

2.Check water pump

The circulating water pump is the "heart" of the heating system. First check whether the water pump is running, listen to whether there is any running sound, and feel whether there is vibration in the pump body. If the water pump doesn't work, check the power supply and controller; if it works but not powerful enough, you may need to replace it with a more powerful model.

3.Clean pipes

Heating systems that have been used for many years are prone to accumulation of scale and impurities. You can ask professionals to use special equipment for high-pressure flushing, or add system cleaning agent and circulate for several hours before draining and flushing. Severely clogged pipe sections may need to be replaced.

4.Adjust system pressure

Too low pressure can cause poor circulation. Check the pressure gauge, it should normally be between 1-2bar. When the pressure is insufficient, fill the system with water through the water replenishment valve to normal pressure. Pay attention to venting again after replenishing water.

5.Optimize pipeline layout

For newly installed systems, ensure that pipes have an appropriate slope (usually 2-3mm per meter) to avoid air pockets. The radiator should be installed at a certain inclination to facilitate exhaust.

4. Routine maintenance suggestions to prevent heating circulation problems

1. Conduct a comprehensive inspection of the system before the heating season each year, including pressure testing and venting operations.

2. Have the system professionally cleaned every 2-3 years to remove accumulated scale and impurities.

3. Install a water quality processor to reduce scale formation.

4. Consider installing an automatic exhaust valve to reduce the frequency of manual exhaust.

5. Keep the system full of water during non-heating seasons to prevent pipeline oxidation.

Most heating circulation problems can be effectively solved using the methods above. If the problem persists, it is recommended to contact a professional heating engineer for a detailed inspection. Remember, good heating circulation not only improves comfort, but also significantly reduces energy consumption and is environmentally friendly and energy-saving.
