Self-heating in a private house: a description of methods and tips for organizing the process

Self-installation of the heating system at home should only be carried out in accordance with the rules and recommendations. To familiarize yourself with them, you should carefully read SNiP 3.05.01-85... But besides it, there are installation features that depend on the design and material of manufacture of heat supply components. And then the question of how to properly conduct heating in a private house with your own hands can be solved without outside help.

General rules for installing heating pipes

Heating installation is carried out only according to a previously drawn up scheme. It indicates the location of the components, their main characteristics and quantity. But besides this, before properly heating the house, it is necessary to study the requirements for this type of work.

The defining criterion when deciding on the installation of heat supply is the material for the manufacture of pipelines. How to carry out water heating in a private house without knowing the specifics of the operation of plastic or steel highways? For polymer products, it is necessary to take into account the temperature regime of the system, as well as pressure indicators. During the installation of steel pipelines, special attention is paid to the fastening of the mains and the connection of individual lines into a single system.

Since it is possible to carry out heating in the house with your own hands only after analyzing all the above factors, experts identify the main requirements for this process:

1. Gravity system - obligatory slope of pipelines 5 mm for every 1 lm. highways.
2. When passing through walls, ceilings or floors, use mounting sleeves. Since heating to the second floor can only be carried out through the ceiling, it should be protected from possible thermal effects.
3. The connection of pipes is carried out only using a special technology. For steel lines, arc welding or fastening on threaded couplings is possible. Plastic are attached after temperature exposure, on glue (very rarely) or using compression fittings.

The optimal fastening step directly depends on the material of manufacture of the pipelines. How to install heating pipes and fix them correctly? For steel lines with a diameter of 25 to 40 mm, it is recommended to install fasteners every 0.3 lm. Plastic pipelines are fastened with a pitch of 0.2-0.25 m.

You can correctly carry out heating in the country with your own hands after analyzing the condition of the walls. The possibility of hidden or surface mounting depends on this.

Open installation of highways

The most popular way to install pipelines in a heating system is open installation. Thus, you can quickly and efficiently carry out heating yourself. But even this method has its own rules.

First of all, it is necessary to draw up a layout of the highways. The best option is considered to be the correct heating wiring in the house along the walls. If the system is gravitational, the required tilt angle is taken into account.

The basic rules for surface mounting are as follows:

1. Distance to floor... The material of the decorative flooring is taken into account. You can carry out water heating in a private house with parquet, linoleum or ordinary plank flooring. The minimum distance from pipes to the floor should be 3-4 cm.This is necessary not only to preserve the coating, but also for the convenience of repairs or preventive maintenance with heating.
2. Distance between flow and return pipe... It should be at least 5cm. Otherwise, additional heat losses will arise and it may be difficult to replace damaged areas.
3. Boiler connections... The water temperature is taken into account. How to carry out heating from a boiler with polypropylene pipes? To do this, it is necessary to install steel pipes from the boiler, the length of which must be at least 1 m.

During heating in the house with your own hands, it is possible that the pipes will be exposed to negative temperatures. Most often this occurs in those areas that are not located in residential premises or outside the house.

To prevent the appearance of ice plugs, the pipes must be insulated. There are several ways to maintain a minimum temperature on the surface of the lines:

1. Installation of insulation... It should not change its properties at high temperatures. It is best to use special mineral wool boxes for this.
2. Heating cable... It works on the principle of the resistive effect. When electricity passes through one of the veins, electrical energy is transformed into thermal energy.

During heating to the second floor, the optimal place for the passage is determined. It must not be located in supporting structures (beams, supporting plates, etc.).

To reduce the hydraulic resistance, before laying the heating pipes, a minimum number of swivel nodes should be provided in the scheme. This will also affect the complexity of the installation.

Closed pipe installation diagram

The open layout of the highways may not be compatible with the interior of the room or the whole house as a whole. To solve this issue, you can conduct heating yourself in a hidden way.

There are several ways to install pipes using this method. Do-it-yourself heating can be done under the floor or in the walls. However, in any case, the features of the material of manufacture are taken into account. To install the highways into the floor, a rough surface is preliminarily prepared. It should be flat, without sudden changes in level. After the pipes have been laid, the concrete screed is poured.

Installation of highways into walls can be done in two ways - into gates or by closing the pipelines with false panels. The first technique to properly conduct heating in a home is to cut grooves in the walls. They are required for installing pipes. After the final installation, the grooves are closed using cement mortar or a similar building material.

For a hidden installation of water heating in a private house, you will need to fulfill the following conditions:

1. It is forbidden to make grooves in load-bearing walls. This can affect the integrity of the entire building.
2. During the heat supply in the house with their own hands, the location of the pipes is taken into account. It must be either vertical or horizontal. Diagonal mounting is not permitted. The same goes for the strobe.
3. The depth of the grooves should be 1-1.5 cm greater than the pipe diameter.
4. When conducting heat supply to the second floor and on critical sections of the highway, they equip inspection hatches to inspect the state of the system.

One of the ways to hide the heating circuit is to install a water floor. It is mounted on a rough surface and then poured with a concrete screed. An alternative option is to install logs on which the decorative floor is mounted.

In this way, you can ensure uniform heating of the air in the house. There is no need to install radiators or batteries. However, for wiring pipes for underfloor heating, careful insulation is necessary. This is especially true of the first floor of the house.

When calculating the depth of the strobes, the size of the mounting elements for fastening the pipes must be taken into account.

House heating system complete set

Having decided on the method of heating in the country with your own hands, you can proceed to the selection of the main components of the system. Their number and type directly depend on the scheme and the required heat supply parameters.

For the minimum configuration and independent heating, you will need the following components:

1. Shut-off valves. With its help, it is possible to limit or completely shut off the flow of the coolant in certain sections of the system.
2. Security groups. Without them, it is impossible to properly conduct heating from the boiler. An air vent and drain valves are mandatory installed. It is also necessary to install an expansion tank.
3. Regulatory components. These include thermostats and programmers.

Detailed completing of heat supply is carried out only after calculating its main parameters. Based on the data obtained, the optimal models of the components are selected, the place and method of their installation are determined.
