They gave heating, and the batteries are cold: what to do

Residents of apartment buildings are looking forward to the start of the heating season: finally, the apartment will become warm and there will be no need to use electric heaters. However, such a situation often arises: the network has already been turned on, and for some reason the batteries have remained cold. What needs to be done to make the room comfortable for living? First of all, you should find out the cause of the problems with the heating system. An analysis of its operation and checking the status of all elements will help to understand what to do if heating is given and the batteries remain cold. Based on the information received, a troubleshooting algorithm for the communication network is determined.

Causes of heating problems

First you need to make sure that the heating was really given, and the heat carrier of the right temperature enters the heating system of the apartment. In the absence of problems with the central network, among the causes of cold radiators are:

• air congestion in the system;
• clogged batteries;
• Incorrect connection of heating network elements.

In each situation, a certain amount of work will have to be done so that the cold radiators become hot.

Air congestion

The most common cause of disturbances in heating is air congestion, which is formed due to a leak, a quick filling of the system, or as a result of heating water. Especially often they appear in the apartments of the upper floors.

To make cold radiators hot, you need to remove air from the system. Modern models are equipped with special exhaust valves located at the top of the batteries, and operate in automatic mode. Also, a Mayevsky or drain cock can be installed on the radiators, with which the air is removed manually.

The Mayevsky crane is a tapered rod with a thread, when unscrewed, a through hole opens and the gas medium is removed from the coolant.

What to do if they are absent? If you gave heating, but the batteries remained cold, you should contact the management company or the housing office and call the plumber to remove air from the system. Typically, a preventive check is carried out after the coolant is supplied to the system in order to prevent its uneven heating.

Connection errors

Another reason why batteries may remain cold; ─ incorrect connection of heating system elements. The most serious mistake is the connection of radiators with pipes, in which water is supplied from below. In this case, the sections are heated unevenly, and part of it remains cold. This is most often characteristic of lateral connection. What should I do to make the surface of the radiators evenly heated and make the apartment warm? To do this, you need to correctly connect them to the system.

Too many sections can also contribute to uneven heating, since the circulation of the coolant is difficult. To improve it, a special extension cord connected to the pipe, which supplies hot water to the battery, will help.

Advice! For uniform heating of radiators, the diagonal connection is the best option, which ensures maximum efficiency of the heating system.

Clogged heating system

Often batteries are cold due to deposits on the inside of the case. The reason for their appearance is various impurities in the composition of the coolant and the products of the interaction of hot water and metal. What to do in this case?

The radiators in the apartment are cleaned in several ways, each of which requires the presence of certain equipment and performance conditions.

If a the battery is equipped with taps at the inlet and outlet of the coolant, then it can be Rinse even when the heating is on. To do this, the radiator is removed and the dirt washed off with a strong stream of water. In case of failure, the sediment from the walls of the body is removed using chemicals. After drying, the heater is installed in its place, and the joints are carefully sealed.

It is possible to remove deposits from the walls of batteries without removing them. This is done using special equipment, using the following methods:

• Chemical. It is carried out using solutions of organic and mineral acids, alkali and other compounds. It is made using special equipment consisting of a pump, a container for cleaning fluid and hoses. The method is indispensable for steel pipes.
• Hydropneumatic. It is used with equipment that can create high pressure. Water serves as a cleaning fluid, due to which turbulent flows are formed, which destroy deposits on the walls of pipes and radiators.
• Hydrodynamic. It is carried out by a stream of water under high pressure, the liquid is supplied to hard-to-reach places due to various nozzles. The cleaning method is effective for heating elements made of cast iron and has a high cost.
• Pneumohydropulse. It is used for batteries and pipes whose diameter is not more than 150 mm. Deposits are removed using a water gun, which can act pointwise.

As a result of a careful study of the causes of uneven heating and its competent elimination, cold radiators will become hot, and the living room will have a comfortable temperature.
