Everyone dreams of a home that will be located at a considerable distance from the bustle of the city. But at the same time, one has to create that comfort that will appeal to everyone living. First of all, it is worth taking care of the heating system by making its high-quality installation. Particular attention will have to be paid to the location of the boiler and the implementation of the wiring of a certain variant of the heating wiring in a private house for various conditions. Pros and cons of typical schemes, their use for different types of coolant circulation.
Beginning of work
When a heating system is installed in a private house with your own hands, first of all, you should pay attention to a thorough analysis of all the conditions under which the operation will be carried out. The area of the heated premises, the choice of the heating boiler, pipeline, its diameter and material, as well as the type of fuel will play no small role.
But the most important thing in this case, which every owner of a private house requires, is efficiency and an excellent level of heat transfer. Each room should be warmed up instantly and to the required temperature. For this, not only the system itself is selected, but also the heating distribution in the house.
Types of heating systems
There are a sufficient number of heating systems that differ from each other according to various criteria. If we take the principle of movement of the coolant, they will be divided into:
Forced. An electric pump is used to distribute water through the pipes of the heating system.
Due to it, the whole complex functions. Most often when buying a boiler, a built-in pump will be included in its kit. But it is worth paying attention to the possibility of equipment dependence on power supply. The heat carrier will not be able to be distributed throughout the system if an accident occurs and the network is lost.
- Gravitational. They are also called gravity. That is, the heat carrier is directed from the boiler to the radiators independently. The principle of convection is present here. The cold liquid is replaced by a hot one. The only drawback in it is that there is a certain limit on the maximum allowed number of radiators connected to the system. She will not be able to fully heat the air in a cottage with several floors and with a large number of rooms. But here there is no connection with power supply, which can be attributed to the number of positive qualities.
When you have decided on the choice of a specific option for the heating system, you need to pay attention to the wiring option. This is what most often plays a significant role in the functioning of the entire heating system.
Classification of wiring
The types of heating systems differ in terms of circulation, the number of pipe circuits and the type of device. Various types of wiring and ways of connecting heat exchangers are used. Consider the options for installing heating circuits in a private house, recommendations for laying pipes.
There are four categories of wiring used in private households.
- One-pipe heating system in a private building. In simple terms, in this case, all batteries are connected in series to the pipe coming from the heating boiler. It is in this sequence, depending on the distance from the boiler, that the coolant will be distributed. Therefore, the further the radiator is from the heat source, the colder it will be. There is no unevenness, which affects a specific room in a private house.
Two-pipe. In addition to a straight pipe with a hot coolant, a pipe from the heating elements, called the "return", goes to the boiler. There is already a uniform heat transfer to all components of the system. The air becomes comfortable in every single room. You should know how to make the heating wiring correctly.
- Collector. The collector is installed not only in each room separately, but also on the floor, if there are several of them in a private house. Subsequently, they are connected to the heating boiler using a pair of pipes. For some specialists, the correct heating wiring looks like this.
- Radiation. The pipe with the coolant rises to a height wherever possible. Sometimes it is even installed in the attic. It is from it that a kind of separate pipe with a hot medium will be directed to the batteries. It resembles a "ray", from which the wiring got its name.
In any of the presented cases, you just need to know how to correctly make the heating wiring.
Before you make the heating wiring in a private house, you should decide on the material of the pipes themselves.
Each of the options presented has its pros and cons, which you should pay attention to during the purchase.
The least popular is the steel version, including the one made of stainless steel. This is due to the sufficient weight of the final design, as well as the complex installation process with them. It will not always be possible to carry out the correct heating wiring in the house with your own hands. We'll have to attract a specialist to carry out welding work. In addition to this, cutting of connections (threads) is required. Such work for heating will take a lot of time.
It cannot be considered the best option and pipes made of metal-plastic, despite the very simple and quick installation of the heating system. This is largely due to the operational period, when it is imperative to check all possible metal connections of the structure and, if necessary, tighten. Therefore, it will be impossible to hide it, for example, in the floor. If, in addition to this, the temperature and pressure in the system constantly "jump", it will not be able to serve for a long time.
An excellent option, but not considered a budget one, would be copper pipes. They have significant advantages, including corrosion resistance and a long service life. The difficulty lies not only in purchasing such an expensive product, but also in installation. To keep the quality at its best, it is better to consult a specialist.
If we consider criteria such as efficiency and functionality, the most excellent option would be to purchase polypropylene pipes for the heating system in a private house. But when choosing, you should pay attention to the possibility of using it in the heating system. A pipe with internal reinforcement made of aluminum or fiberglass is suitable here.
To begin the installation of a heating system with a one-pipe wiring, it is best to purchase and install regulators on the batteries. They can be represented as taps or valves. This will make it easier to distribute the water pressure in the system. In addition, a balancing valve is purchased, located on the pipeline itself.
There are two main options by which this correct heating wiring in a private house is performed. Is it horizontal or vertical. The first was popularly named "Leningradka". To begin with, it is worth stopping at a horizontal arrangement. The name implies that the pipeline should be located around the perimeter of all rooms. Installation can be carried out in the floor or on top of it along the wall. Everything will depend on the preferences of the artist. The main thing is to maintain at least a slight level of inclination as it decreases from the heating boiler.
It is also used for private houses with several floors. But here you need to understand how to correctly make the heating wiring in the house. A vertical riser is connected to the first radiator of the second floor. Even in this case, it is possible to control the water pressure, as well as temperature conditions. For this purpose, a tap is made of its own crane on each floor into the pipeline. The only disadvantage of using this wiring option is the need to purchase a pump that allows water to circulate in the system. Of course, you can do without it, but in this design, the heat transfer will be reduced to minimum indicators. But even here you can do the wiring of the heating system yourself.
In a different way, everything happens with a vertical wiring of a one-pipe system. In the direction from the boiler to the attic, the pipe is laid in a vertical position. A kind of branch is made from it to each battery in the rooms. There is no need to use a pump here, since the method is considered gravitational. After heating the water in the system, it goes up, and only then goes down. The main disadvantage is the need to purchase pipes with a large inner diameter. Moreover, it will be almost impossible to hide such system components.
For the correct installation of a heating system with a two-pipe wiring, two circuits should be installed: a pipe for supplying the coolant to the batteries and returning it back for heating. To connect the radiators themselves, a parallel option is used. Due to this, the location of the lower piping is allowed, as well as independently adjust each component. If, at the same time, one of them is brought to the ideal, this will not in any way affect the performance of all the others.
These options for heating distribution reduce the existing disadvantages of a one-pipe system, having reduced energy consumption and a higher degree of heat transfer. The entire area of the room will be warmed up evenly without temperature fluctuations.
Additionally, the installation of air vents on radiators, as well as a shut-off valve at the point of supply of hot media, is carried out. This allows you to control the temperature of each battery in the room and individually. There is no need to install shut-off valves on the return.
This type of wiring cannot do without drawbacks, which are manifested in the consumption of materials during the installation of the heating system. After all, you will have to purchase a double number of pipes compared to the one-pipe version.
In the heating system, a high-quality installation of the circulation pump should be made. Only then can the supply and return pipes be placed. If natural circulation is used, it will not be able to direct the coolant through the system. Initially, for example, water is supplied to the collector, after which it is directed through all components, warming up the air inside the premises of a private house.
As a component, shut-off valves are used, which must be located at any collector outlet. Despite the initially huge amount of money spent, everything will pay off soon. In addition, there are other advantages that these methods of distributing heating in the house can boast:
- No circuit is dependent on each other. Each room can have completely different temperature readings. If necessary.
- During the operation of the heating system, it is possible to replace individual radiators in case of their failure and reinstall them. After that, all that remains is to include them in the system.
- A separate cabinet is intended for the collector, not significant in size, and the entire pipeline is perfectly hidden under the floor or in the walls. Everything will depend on the interior.
- You can connect a warm floor to this system.
You can start the installation process yourself. The main thing is to strictly follow the sequence of the implementation of all activities.
If you look at the structure of the wiring of the heating system, you can come to the conclusion that it is a kind of a kind of two-pipe version. The only difference is the use of additional units and components during installation, which make the entire system more practical and economical.
This is reflected in the excellent transfer of heat from the batteries to the interior, and the energy consumption is significantly reduced. The payback period will take a much shorter time period. These methods of distributing heating in a private house are used more and more often.
Heating system efficiency with circulating pump
The circulation pump in the individual heating system plays an important role. If you need to quickly heat the air in the rooms of the house, and the efficiency of the heating system must be high. The conversation is about heating devices - radiators, underfloor heating systems. The faster the radiator makes heat exchange between water and air, the more efficient the entire heating system will be.
Individual heating systems, we must ensure that the radiator that has given off the heat does not cool down by itself and the water at the outlet of the radiator does not turn very cold. In other cases, the boiler will wear out, which is not good. This is where a circulation pump will help us, which will maintain the circulation of water. Which will allow the radiator to keep the temperature, and return the water not overcooled to the boiler.
In this case, the heating system with natural circulation disappears - ineffective. First of all, due to inertness, the speed of the water directly depends on the temperature of the water. We are waiting for the water to heat up and then cool down, here it is a slow and ineffective way.
We turn on the circulation pump and eliminate all natural plugs associated with temperature differences. Individual heating systems circulate any water - cold, hot it all depends on how it managed to cool down or heat up. The water goes into the system and returns back at the same speed to the boiler.
What we have? Reducing fuel consumption in the boiler. Suppose you need a coolant temperature of 65 *. Individual heating systems, the water is cold, the boiler is operating at maximum. The temperature rises, the water does not have time to completely cool down in one pass through the heating system, the boiler goes into an economical cut, maintains the temperature. If the output is 65 * and the input is 60 * then in each radiator it is heated up to 64 * and the bottom is up to 61 * degrees. So the radiators give full power, the boiler does not have to heat the water up to 70 * -75 * degrees and more to spend additional energy. In this way, we have the ability to set the temperature for each radiator separately. If we have a warm room and a kitchen, then the temperature of the radiator can be lowered, and we will get additional savings. The circulation pump driving water through the heating system gets convenience when you need to set the radiator to 35 * degrees (heating system with natural circulation is not possible) autumn and spring months, cool but not cold.
Individual heating systems with Circulation pump, we install small diameter pipes. What will it give us? It will give savings in the purchase of pipes, reduce the amount of water in the heating system and gas costs for heating water and the speed of heating.
Natural circulation can be used in all the variants of heating systems with wiring. An expansion tank should be provided in it, where the coolant will be located when the temperature rises. This in turn helps to control the level of its pressure, eliminating damage to all equipment.
The connection of all components of the heating system is carried out in the upper wiring. Only in this case, the coolant will be able to evenly distribute over the heating radiators and transfer the required temperature level into the room. The slope of the pipeline will play a huge role here. It will be designed to supply directions for the coolant. Usually, during installation, an angle of 5 degrees is chosen, which will be sufficient. Its advantages can be highlighted:
- No dependence on electricity, as is the case with a circulation pump.
- No noise during use.
Ease of use.
But all the disadvantages are much more. The main thing is the complexity of the installation work. After all, here you will need to create a constant slope along the entire length of the pipeline. It should be maintained for every running meter. It cannot be used in private houses if the total area is more than 100 square meters. In the case of using metal pipes and radiators, over time, water as a heat carrier will lead to corrosion. At the same time, apart from water, nothing else can be used in the heating system. Also among the minuses is the large flow rate of pipes when heating wiring in this design is required.
With regard to private houses on two floors, there are certain requirements for the choice of wiring and its high-quality installation. In this case, the two-pipe heating system is endowed with the greatest versatility. In this case, you can come to even greater efficiency of its work, if you install an adjustment tank in front of each radiator.
In a two-story building, natural circulation can be used. Here it will be sufficient to locate an expansion tank in it, not in the attic, but on the second floor. During installation, the supply pipe is mounted under the window sill in the room or under the ceiling. If you replace all this with a circulation pump, an additional source of heat in the room can be used - warm floors, as well as heated towel rails. And this can be done not only on the first, but also on the second floor of the building.
In any case, everything will depend on the quality of the installation, which allows you to get real comfort in every room inside a private house. When there is no knowledge of how to make heating wiring with your own hands, the best option is to attract specialists. It is they who will finish the work within the allotted time frame and with high quality and know how to correctly do the heating wiring in the house

Do-it-yourself electrical wiring in an apartment It is believed that, on average, a modern apartment consumes about 8 kilowatts of power. So a 40 amp circuit breaker should be used. This is enough to protect against overload and short-circuit current. Residual current devices (the so-called RCD) are needed to protect people from electrical injuries, as well as during power surges. Most often, 2 RCDs are installed, one with a leakage current of 10 milliamps (for a bathroom) and the second
