First、Valve was closed, turn on the valve will be ok, this is the mast common
Secondly, the air did not release , hinder the way of water , so that the radiator could not dispel thermal it is also easy. Through the exhaust or run wind deflated.
Third, the pipes of radiator are enter from underside and leave off also from underside, the radiator is only hot in the underside ,but the upside not hot.There may some reasons：one is the installation of radiator inverted, that is, put a radiator fitted with the retaining film to the top, the bottom has become a straight-through processing of the water wholly gone from the foolowing, because there is tables should not retaining water exchange caused the radiators’top is not hot, and half of the radiator is not hot, and some half of the radiator hot ,half hot,also retaining films causes
Fourth, only the front radiators are hot , the back is not hot? If the layout of your home channels are single-tube series will appear this is the case, as soon as turn off a group radiator others will not hot . If the import water at a temperature of 75 degrees, after the first group after the outlet into a 65 degree or 55 degrees re-entering the second group, the second group of exports of the water temperature becomes 55 degrees to 35 degrees, to the last positive change into the radiator is not hot. This situation is the best way to solve the re-take the pipeline, and the second circulating pump add. This is no good method for it. This condition is generally made by fool
Fifth, the parallel pipelines in the radiator is not hot and hot some of the non-uniform main valves are non-regulated, and have used is not enough crude pipeline, amounting to less than a standard radiator will not heat, generally 100 of the cottage room the following 6 sub-channels required can be, but the minimum water flow to achieve h/49 kg. 100-180 cottage required one-inch pipe, this tube is good, that is, that group can adjust the radiator temperature and room temperature. One is beginning to adjust to the requirements plumbers Well. Have put the worst of a pipeline wall is smaller during the construction or plugging of the will is not hot, this is no way to solve.
Sixth, they come and out are all from above, it was certainly not hot, unless it is steam and radiator pipes and vertical risers that are likely to have hot spots, if not hot, not hot Principle automatic hot and cold water are the role of convection, hot water will always be his own rise, sinking of cold water automatically, and radiator are not so hot. Solution is to put a pipeline into the next upward mobility,or come and out from the under.
