Reasons for the Failure of Return Pipe of the Floor Heating
Model: heating system, flooring, cold flooring | Date:2024-11-02In such a cold winter, floor heating has become a necessity for many households. However, after turning on the floor heating, many people may encounter the issue of the return pipe of the floor heating manifold not getting warm. So, what are the reasons for the return pipe of the floor heating manifold not getting warm? What should be done when this happens? Let me answer these questions for you below.
Reasons for the Return Pipe of the Floor Heating Manifold Not Getting Warm, and Solutions
Insufficient Pipeline Pressure
Reason: Some households may experience less-than-ideal heating due to being located on a high floor or at the end of a heating district in a residential complex.
Solution: Water requires a certain amount of pressure to flow through floor heating pipes. If the pressure is insufficient, the pipes may not get warm. In this case, you should contact the floor heating company or the relevant property management to resolve the issue. They typically install a circulation pump to enhance the circulation of heating water and achieve the desired heating effect.
Air Trapped in the Pipelines
Reason: The main heating pipe is warm, but the return pipe is not. This may be because air is trapped in the pipeline, preventing hot water from entering the circuit and circulating.
Solution: In such cases, first close the return valve and manually open the exhaust valve of the floor heating system to drain the water. Make sure to close all inlet valves first, and then open the exhaust valves one by one. Water may overflow during this process, so remember to use a small basin to catch the water.
Filter Clogging
Reason: The main water supply pipe is not warm, which may also be due to dirty heating water causing the filter to clog and preventing normal circulation.
Solution: If this is the case, use an adjustable wrench to open the filter, clean the filter mesh inside, and reinstall it. Alternatively, you can seek professional cleaning services.
Lack of Regular Cleaning of Floor Heating
Reason: Inadequate or untimely maintenance of floor heating equipment can also cause the floor heating to be ineffective.
Solution: Generally speaking, floor heating pipes should be cleaned once every 3 to 5 years, depending on specific conditions. Ideally, before the heating season each year, it is best to have professional floor heating cleaning companies perform maintenance on the floor heating equipment.
Uneven Heating Circuits
Reason: If other users in the same residential area have good heating effects, but your own heating effect is poor, it may be due to uneven heating circuits during the installation of floor heating.
Solution: Use the small valves on the floor heating manifold to adjust the circulation of each circuit, ensuring even circulation and achieving the desired heating effect.
Valves Not Opened
Reason: If the inlet pipe of the floor heating system has hot water flowing in and the inlet pipe itself is warm, but the return pipe is not warm, this is likely caused by the main valve not being opened.
Solution: Check the main valve on the floor heating main pipe and the manifold in sequence to see if any are closed. If so, opening them will solve the problem of the return pipe not being warm.
Failure to Drain Water After the Heating Season Ends
Reason: Some users fail to drain all the water from the boiler pipes in the geothermal piping network in a timely manner after the end of the annual heating season. The water in the boiler pipes contains a lot of mud and impurities, and long-term accumulation of scale without cleaning can reduce flow and cause poor water circulation.
Solution: After the end of the annual heating season, drain all the water from the boiler pipes in the geothermal piping network in a timely manner.
Issues with Geothermal Installation
Reason: The installation personnel may not have undergone professional training, leading to irregular installations. This can result in dead bends, flattening of pipes, and other issues that impair water flow and increase resistance.
Solution: Carefully clean out debris inside the pipes to keep them clean.
