How to repair heating in a private house?

What to do if the radiators are cold

Heating system of a private house –

This is the optimal solution for providing comfortable living conditions all year round, so the installation process must be carried out professionally and using high-quality materials and equipment.

But even with a high level of installation, sometimes the heating system of a private house

malfunctions -
sections of heating radiators
,
pressure in the heating system drops,
poor circulation and other problems.

A common situation is that you have been away for a long time and, for the sake of economy and safety, heat the country house

turned off.
After turning it on, you notice that not all sections of the heating radiators
are warming up, and
the pressure in the heating system
is low.

Damage to polypropylene pipes

It is more difficult to detect leaks in such pipes than in metal ones. Since polypropylene products are not subject to corrosion, only droplets appear on their surface, which quickly disappear under the influence of high temperature.

Measures to be taken when leaks are detected:

1. Before eliminating a heating pipe leak, it is necessary to turn off the area where a small leak has appeared or a breakthrough has occurred.
2. Drain the water from the disconnected area.
3. Carefully remove the thermal insulation of the pipes if the area is insulated.

Leaking polypropylene pipe

Often the insulation is secured with foil tape, which is not recommended to be reused - its adhesive qualities are lost.

1. Dismantle the pipeline. It is advisable to do this in the case of an extended section, at the point of soldering or between nearby fittings. When a breakthrough occurs at the location of the fitting or welding, it is recommended to replace the welding site with a piece of new pipe, and replace the fitting with a new one.
2. Installation of a new fitting or section. When soldering pipes, it is necessary to observe the standardized soldering, heating and cooling times. Violations of installation technology may be the cause of an existing defect. When replacing heating pipes, products of the same type and diameter must be used.
3. Run water into this area again, bleed off excess air and start the system again.

After completion of the heating system repair work, there is no need to reinstall the thermal insulation within 2-3 days to monitor the work performed.

1. After repairing a separate connection or installing heating pipes, periodic monitoring is required over this area. During the first hours after starting the system, you need to check the repaired area every hour for new leaks. This will reduce the risk of a new emergency.

Experts say that leaks or breakthroughs that occur in the same places indicate that the system is not properly balanced - there are different pressures in different areas. In this case, it is necessary to perform a detailed verification calculation of the heating system and determine a method to eliminate the problem. In most cases, the diameter of the pipes in the problem area is changed.

Low pressure in the heating system of a private house

Causes

Heating system of a private house

includes
boiler equipment
such as a gas heating boiler (solid fuel, diesel or electric),
heating manifold
, circulation pumps, expansion tank, pipe distribution and
heating radiators made of aluminum,
steel, cast iron or bimetallic. The system may also include a water heater (boiler).

If each element of the system is correctly selected and correctly installed, there should be no problems or interruptions in operation, but sometimes, for example, after a long period of inactivity, low pressure in the heating system may be observed.

This is due to the fact that there is air in the system, which gradually escapes through automatic air vents or when de-airing radiators manually.
Therefore, at first, the heating system of a private home
may require frequent top-up.

If more than a month has passed since the heating system of a private home was started,

the pressure in the heating system
still , the reason may be in the expansion tank, or rather, in an incorrect calculation of its volume. Then the safety valve releases the water and the pressure decreases as it cools.

If everything is normal with the expansion tank, the reason is that the tightness of the system is broken. This may be due to the fact that when heating was installed in the house,

did not pay enough attention to commissioning, or there is a leak somewhere.

If the heating system boiler

and the pump are working, but there is no circulation of coolant in the system, it is necessary to check
the radiators for heating the house,
it may be airing.
Often the reason is closed taps. Next, you should clean the filters. As a rule, these actions guarantee 90% that the heating system of a private home
will work.

But if all of the above steps do not help, it is best to contact specialists who will repair the heating system

quickly and efficiently, they will carry out diagnostics and commissioning of heating equipment.

Home heating system repair

Repairing a home heating system requires accurate identification of the fault and careful inspection of all elements. In addition, the entire system must be checked for errors in design and assembly. Malfunctions can be associated with precisely such errors, and replacing a certain element can only lead to further breakdowns. Heating repairs can be classified into current and major. Current repairs involve replacing and repairing elements that have worn out over time. Typically, this involves eliminating leaks and carrying out minor repairs to pumps and boilers. Carrying out such work does not require stopping the entire heating system. Major repairs are required in case of wear of numerous components and parts. It involves a complete replacement of the boiler, pipes and installation of new radiators. The need for major repairs occurs quite rarely. However, the frequency of replacement and re-equipment depends on the quality of the purchased pipes and units. In this regard, you need to purchase products from companies that have earned a high reputation in the market.

Heating pipe repair

In order for the country heating system
to work like a clock, providing a normal level of heating and hot water supply, during the installation process it is necessary to pay maximum attention to the design, installation and selection of system elements, especially with regard to pipes.
Often, in order to save money, owners install plastic pipes, since they are cheaper than copper ones, but, unfortunately, they do not justify themselves and fail much earlier. Therefore, pipe repairs have to be carried out.
The weak point of plastic pipes is their connections, so they should never be hidden in walls. The exception is copper heating pipes.

So, a leak is detected - it doesn’t matter whether it’s a water pipe or a heating pipe, what needs to be done:

1. Disconnecting it from the water supply (heating) is good; when a country heating system was installed,
   a collector was provided, then you won’t have to sacrifice comfort, especially in winter, and turn off the entire system.
2. If the leak is caused by fittings, it is enough to replace them with new ones, but if a pipe bursts, you will have to reinstall it, since repairing a plastic pipe
   in heating and water supply systems is useless - due to the high pressure, it will leak again. Alternatively, you can cut out the damaged piece and weld a new one, but since it is plastic, there is no guarantee that the joints will not begin to leak over time.
3. Repairing
   plastic pipes most often involves their dismantling, therefore, it is better to immediately install
   copper pipes for heating,
   at least in this area.
   With the help of adapters, they can be combined with plastic, and the soldering of copper pipes
   is sealed and will not be damaged even during pressure surges. In addition, they can be hidden in the wall, unlike plastic ones.
4. After the heating pipes
   have been repaired, it is necessary to turn on the system, but do not immediately apply high pressure, first check the reliability of the connections, and then diagnose the system.

Repair of heating pipes in a private house

You can do it yourself if you have the skills, but it is better to turn to specialists, preferably those who installed
the country heating system.
They will carry out the entire range of work much faster and with better quality, and will also check and adjust the normal operation of heating equipment.

Malfunctions and ways to eliminate them

Operating water heating can also cause problems. Malfunctions that occur in heaters or fittings can be solved yourself, but in the case of restoring boiler equipment, experience and special knowledge are required. Such problems are better solved by masters.

1. Weak heat transfer from radiators

Poorly heated radiators can be due to several reasons:

• the heat supply system became airy and, as a result, air pockets formed;
• as a result of long-term operation without proper care of the heating and water supply structure of a country house, or due to the use of low-quality coolant, the heating device could become clogged with dirt. Such a radiator will no longer be able to give off the heat that a new and clean device can give off;
• due to coolant leakage or partial evaporation, the pressure may drop;
• installation work of the heating system in a private house was carried out with violations;
• and another rather rare problem - someone turned off the coolant supply valve to the radiator.

To get rid of air in the system, it is necessary to lower it using Mayevsky cranes. When working with the tap, you need to place a small container under it in case of coolant leakage.

If the structure cannot be repaired, then it is worth flushing the system. To do this, place a bucket or basin and unscrew the plug. Draining is done until the water is clean. If this does not help, you will have to dismantle the radiator and flush it entirely.

The pressure problem is dealt with by the circulation pump and the expansion tank. To create more pressure, you need to turn the coolant supply tap into the system and use a pressure gauge to determine how much is needed. This is a typical problem for double-circuit heating boilers.

1. Insufficient pressure in the system

If periodic pressure surges occur in the system, problems may be caused by the following reasons:

• leaks;
• poor air outlet from the system;
• new aluminum radiators are being tested.

To find the location of the leak, you need to inspect the entire system. In such places you can find drops of water or white deposits. The leak may also be in the boiler equipment or circulation pump. To check the tank for problems, you need to press on the nipple. If water appears, care should be taken to replace the membrane.

A fairly common cause may be a heating system that is not filled with coolant according to the rules. Air should be released during the first work with starting the system and emergency blocking of the system. Subsequent circulation of the fluid will cause a drop in pressure. In such cases, it is necessary to drain the water at the farthest radiator, not forgetting to turn on the water supply valve to the system.

1. No circulation

There are two ways to achieve fluid movement through the heating system: using a pump or convection. If there is no circulation, the radiators will not heat up. The reasons for this may be dirty pipes and pump malfunction.

Heating boiler repair

Heating boilers are the most complex element of heat supply. It is almost impossible to restore their functionality in the event of a breakdown on your own. Therefore, before repairing diesel heating boilers or their other analogues, you should analyze all possible consequences.

First you need to check whether the warranty on the equipment is still valid. If this is indeed the case, you need to call specialists to fix the problem. Self-repair of electric heating boilers may result in premature voiding of the warranty.

But primary knowledge about the cause of the malfunction will help the specialist. You can describe the emergency situation over the phone. The company representative will take with him the optimal set of tools and components necessary for replacement.

Repair of electric heating boilers may be necessary in the following cases:

• A sharp decrease in heating of the coolant;
• Failure of the control unit;
• Heat exchanger failure – leakage;
• The influence of third-party factors that led to the breakdown - a sharp surge in voltage in the network, overheating of the coolant.

Often the reason for the repair of diesel heating boilers can be the quality of the fuel used. In this case, you can clean the injector yourself and check the primary fuel heating unit. If these actions do not solve the problem, you will have to call a specialist.

But there are a number of breakdowns that cannot be eliminated by repairing electric heating boilers. First of all, this concerns the destruction of the housing and the lack of maintainability of the heat exchanger. In these cases, it is more advisable to purchase new equipment than to repair diesel heating boilers.

After the repair is completed by specialists, a note about this fact is made in the warranty card. If the breakdown is due to a manufacturing defect in the equipment, you can request an increase in the warranty period.

First steps in the event of an emergency

How to wrap a heating pipe? If you have a couple of clamps with rubber seals in stock at home, you can prevent some emergency situations. In the event of an accident, the most important thing to do is to shut off the coolant supply to the area where the heating pipe is leaking.

Covering the heating riser of a multi-storey building

You will need to stop the heating boiler, turn off the pump and turn off the necessary taps and valves. The clamp will solve the problem temporarily, so repairs will still be inevitable. Before you begin the repair, you will need to prepare the necessary materials and tools, turn off the heating, turn off all taps and drain the water from the system. Depending on the material from which the pipes are made, repairs can be carried out in various ways.
