Replacing heating radiators: coordination, work with risers,

The need to replace radiators arises more often than it seems. The replacement process is fraught with many nuances, ignorance and non-fulfillment of which leads to different situations, additional expenses of funds and nerves. Today we are interested in replacing radiators in the apartment with their own hands. We will understand.

Replacing replacing strife

Even this process involves several action algorithms:

• Algorithm One - Easy Replacement;
• The second algorithm is the replacement of the radiator with the change of the piping scheme, the installation of valves and other elements of "competent installation".

Note! In this material, we do not understand the radiators by type and type, it does not matter. It is much more important to understand how, what should happen and in what sequence, how to avoid mistakes, which are crucial.

Simple algorithm

A simple replacement says that the previous owners or you yourself took care of the correct insertion of radiators into the system in a timely manner. In this case, you are spared initially from a heap of problems.

You do not need:

• To negotiate the replacement of radiators in the apartment. This is because there is no need to turn off the risers in the basement, to warn neighbors about the heat off for a certain or indefinite time;
• To be afraid of flooding the neighbors from below with that water that suddenly pours from the system.

And what should be:

• Shut off the flow to the radiator, exit from the heater into the overall water system;
• Unscrew the coupling nuts and let the water out of the radiator spill onto the pan you are cooking;

Tip! Usually, the replacement of radiators involves the replacement of old cast iron batteries with modern ones, or the same cast iron ones, but serviced. That is, cleaned, checked, collected by the rules. Cast iron radiators are heavy constructions, one section weighs 7.5 kg, how much your entire accordion weighs, it is not difficult to calculate. Therefore, it is better to work together, to collect water from the pan into buckets, substituting new ones and carrying the filled buckets together is also easier.

• Remove the old heater, assemble a new one according to the piping scheme, so that the outlets and entrances, the Mayevsky taps and the blind plug coincide with the previous version;
• Install a new battery and connect it to the input and output.

Nuance! When installing the mounting kit, for sealing it is better to use flax fiber + special paste. In this case, flax is wound on the thread against the thread stroke, and the paste prevents wrinkling of the material and the formation of ridges during the twisting of parts. The service life of such a dock is commensurate with the service life of the crane itself.

Difficult replacement: step by step

Any difficult problem is solved, it is necessary to split it into smaller ones and it will go.

Consider:

1. Questions coordination - without them nowhere;
2. Features of work with risers;
3. Pipe configuration change;
4. Replacing the radiator.

Note! We are considering the problem of how to replace the heating radiator in the apartment correctly, the questions about the possibilities of saving are already embedded in the basic software. In the course of reviewing the material with separate links, we will tell you what is better to refrain from in the process of replacement.

Matching

The absence in the apartment of a separate set of valves for each radiator, says that the coordination issues you can not avoid. The explanation here is very simple - working with the unit for heating an apartment implies the need for neither much nor small - shutting off the riser, on which all the residents of the porch are located on the floors above and below.

This is done in two ways:

• The first is to write an application in the housing office and having received permission and a specialist in addition, you proceed to dismantle;

Tip! In addition to the guarantee of shutting down exactly the riser that is needed, you will receive an adviser who can not only suggest something sensible, but also, by agreement, will help you with repair work.

• The second is in emergency order. Unfortunately, such situations are quite possible, especially in homes where the batteries have not changed since the time of the first settlement.

Reminder! Do not forget to notify your neighbors, especially those below you. Why, you will understand from the next section. And yet, some would-be experts advise not to contact the housing office, offering independent intervention. It is better not to do this, do not forget that such actions are dragging fines.

Work with risers

So why?

Why we do not recommend to carry out independent shutdowns of risers when replacing radiators:

• A slight movement of the hand is not always easy. Without knowing, perhaps, your riser can block the next. This is still half the trouble;

Note! Shutting off the water, some owners, to save time, immediately grab the grinder to dismantle the radiator, forgetting that the water in the pipes will create all the prerequisites for an electric shock.

Now, about the actions necessary for safe dismantling.

So:

• To begin with, we will need welding when replacing radiators. Naturally, we will work gas welding, not electro. Explanation - the danger of electric shock. Welding in the discharge pipe we make a small hole half a centimeter in diameter to drain the excess water. And only in the absence of water, you can grind a grinder of metal and dirt inside, which was once called a radiator;

Tip! Excess water can be drained by unscrewing the bottom blind plug, but options are possible. Old batteries are full of dirt and rust, it is possible that some of the water will go, and some, especially in the docking area, will remain. Your task is to remove water from pipes for safe metal cutting.

We conjure with pipes

Some masters - lovers of progress, recommend, removing the battery, remove the pipe, replacing them with polypropylene, metal-plastic.

Note! Change the pipe is not worth it. Metal-to-plastic adapters are the weakest links in the network; this is where leakages and accidents are possible. Therefore, the conclusion is unambiguous: if the heating pipes are represented by metal, install metal in it, if there has already been a replacement for plastic analogs, then the tie-in for the purpose of lengthening will be done with a similar pipe. Simply put, similar to like.

When working with pipes, pay attention to the following points:

• Metal pipe elongation is easy to do with the same welding. The “gold seam” cannot replace any existing threaded connection;
• No matter how much you would be told about the beauty of parallel lines, the pipes should not run parallel when connecting to the radiator. The top one comes up at a small angle from top to bottom, the second one goes off at a small angle in the indicated direction. Thus, the possibility of airing the system is prevented;

• A few words about the bypass. This is a very useful jumper in homes where heating schemes are represented by risers. It will allow the circulating coolant to circulate normally during an emergency shutdown of the radiator. It is exposed no further than half a meter from the riser between the pipes.

Heater Replacement

Replacing and installing radiators will no longer be a problem; the principles are described with a simple replacement path.

The steps are the same:

• Installing the installation kit on the heater do it yourself;
• Installation of valves on pipes;
• Docking pipes and assembled radiators.

Tip! When replacing types of radiators, it is often necessary to change the mounting radiators. In modern mounting kits, the mounting brackets are included in the sets, their price is small, but you can place the radiator correctly, without distortions. In panel radiators mounting already included.

Finally

The cost estimate for the replacement of radiators sometimes seems overestimated, but it is these investments that will allow you to do all the work yourself in the future, and therefore save money. The video in this article is ready to visualize this important topic.
