If the overall home heating thermal heating is not reason, may be due to outdoor water backwater valve is not open; locally is not hot, may be due to the top-level deflated; radiator half hot half cold, from the tail gas gathering. In short, in the case of assurance cycle pressure, temperature, heating is not the main reason for the gas block, can release tube gas gathering. Release the the tube gas gathering detailed method: Each radiator has a manual vent valve, the user can gently loosen the exhaust valve manually, hear the exhaust sound immediately stop twisting the exhaust valve, and see if there is a stable water outflow gently tighten the exhaust valve. If not careful to twist off the exhaust valve, and immediately find a wooden chopsticks sharpened one, insert the vent, to avoid a large number of leaking. Then, to find professionals for maintenance. After row over gas, if the radiator is not hot, to professionals to identify heating is not the reason, to help solve the problem, turn on the water must not blind. Nino remind residents, heating is not how to do, do not use water in the district heating system release, otherwise it will damage your health. He explained, centralized hot water heating pipes in conduction heat media media under high temperature and pressure in the closed loop system, heating prevent pipe, valves, corrosion and rust, to ensure smooth supply and return water cycle, water plus a certain amount the chemicals, the water quality is totally inconsistent with the standard of living water. In addition, the release of the water in the heating system, heating system can also cause serious water shortage, the heating system pressure imbalance, leading to partial or full heating system is not stable heating, affect the normal heating Contact: Tao Zefeng Phone: 4007005525 QQ : 860 357 491 Heating is not hot how to do: http://www.nuanqi.cc/?article-54.html radiator: http://www.sllssrq.com/ radiator Mall: http://www.nuanqi.cc Beijing Daxing District, Crystal Plaza the Huatang Mall 1201
