Analysis of several reasons why the radiator is not hot in winter

The most disturbing thing about heating in winter is that the heating is not hot. The specific reasons are generally two major categories. One is the reason for the heating system, and the other is the reason for the radiator itself. Xiao Bian summarizes the main reasons why the radiator is not hot. It is convenient for Qijia netizens to self-check.

Reason one:

Some iron pipes were connected in series in a single house. In the early stage of heating, because individual businesses did not open the valves of their rooms in time, the circuits were not smooth or interrupted, resulting in the heating of the neighbors of the entire unit up and downstairs. Solution: First make sure that your home's valve is open. Ask the neighbours who are upstairs and downstairs.

Reason two:

A large amount of air accumulates in the radiator row, which can also cause the heat radiation gas to be not hot. In the initial stage of heating, some residual air in the original piping system will accumulate in the pipes and radiators of the heating system, causing the phenomenon of obstructing the circulation of hot water, among which the roof of the building is more prominent among the homes. Solution: Open the air release valve on the side of the radiator and slowly drain the product until hot water is released.

Reason three:

Some cast iron radiators with relatively long service life, especially some old cast iron three-column or four-column cast iron radiators, are old in shape and have fouling on the inner walls, causing poor water flow and reduced thermal conductivity, which directly affects the heat dissipation effect. Solution: Replace the new radiator.

Reason four:

Heating system is not up to standard. As the urban heating area increases year by year, the heat supply at the heating station also increases year by year, resulting in many places where the district’s original designed heat supply and heating area do not match, forming a “small horse-drawn cart”. ". The concrete manifestation is that the building heat is near to the heat source, and it is not hot in the distance. Or some rooms in one building are hot and the other part is not hot. Or it is hot in the upstairs and it is not hot downstairs. These phenomena are collectively referred to as system disorders. For those who have not changed the heating system, the solution is to find a thermoelectric company.

Reason five:

Pipeline transformation did not do a good job. During the renovation of the house, the reconstruction of the heating pipe was not done well. For example, the system was selected incorrectly, the construction was poor and the pipe was clogged, and even leaked. Or because the design was unreasonable and the system circulation was affected, the radiator was not caused by this situation. Heat is the hardest thing to deal with. It is often difficult to determine the cause and find the root cause.
