Water heating of a private house

The heating system in any room plays a significant role, but in private homes it becomes key. The closed circuit of the system, its proper functioning and the ability to start at any time in the presence of a coolant ensure a comfortable stay in the house throughout the year.

When choosing one or another type, the water heating scheme of a private house is very important, according to which its subsequent installation is carried out.

According to the principle of organizing work, the heating system is divided into 2 main types of circulation:

• forced;
• natural.

Forced heating system

Forced supply implies the presence of a pump that pumps the coolant into the system and ensures its circulating movement.

The pumping equipment is always installed at the return point of the chilled water to the boiler.

The heat carrier in the heating system is a liquid or gaseous substance that transmits thermal energy. In domestic heating systems, water with the addition of lubricants is used as such a substance. The main requirement for coolants of any type is the inadmissibility of corrosive effects on the entire system.

Natural heating system

With the natural circulation of the coolant in the heating system, the laws of physics apply when warm water moves up, and cooled water, on the contrary, goes down.

There are certain rules for the installation and operation of a heating system with natural circulation of fluid, namely:

• the expansion tank is always installed above the radiator;
• the lower return point must be installed under the heating device;
• between the extreme points of the pipeline there must be a difference of at least 5 degrees;
• the diameter of the supply and return pipes never coincides, while the supply pipeline should have a larger cross section;
• the entire pipeline is mounted with a small height difference, when water moves in a natural flow to the batteries from the tank and back to the boiler.

The water heating scheme of a private house with natural water circulation implies absolute autonomy from any energy carriers.

Heating schemes

The peculiarity of the heating system lies not only in the method of supply and movement of the coolant in the pipeline, but also in the organization of the latter along the perimeter of the room.

So, one- and two-pipe systems are distinguished, where the one-pipe one consists in connecting radiators in series (one after another), and the two-pipe one - in an independent one.

In the first case, water moves freely through pipes and radiators, gradually cooling and giving off its heat. In fact, this is a large ring where water constantly circulates.

In the second - all radiators are independent of each other and the movement of the coolant is carried out almost simultaneously. This method ensures uniform heating of the room over the entire area, where the heat transfer of each device is almost the same.

Features of a one-pipe system

It is no coincidence that such an organization of heating is considered the simplest and therefore the most popular option. Among other features it is worth noting the following:

• minimum budget due to material savings;
• simplified installation;
• the ability to carry out any repair work independently;
• the pipeline is mounted in any convenient place - traditionally under the windows or as an element of the "warm floor" system;
• can be installed in one- and two-level rooms.

Follow the correct sequence of connecting radiators for optimal operation of the heating system.

Why is it beneficial to install a two-pipe system

Despite the significant difference in price, it is the two-level heating scheme of a private house that is the absolute leader in installation. On the one hand, this system is absolutely universal and can be used in premises of any size, number of storeys and operating conditions. On the other hand, all radiators have almost the same temperature, which allows you to heat up the room faster and more evenly.

Each convector/radiator must be equipped with a regulating choke to equalize the temperature at all connection points.

How to install

At the first stage, you draw up a heating scheme for a private house, where you provide for the number and type of elements and the wiring method.

The number of radiators is determined by the area of ​​\u200b\u200bthe room. So, for every 3 sq.m. there is one section of a steel or cast iron radiator. In the case when the thermal insulation is broken in the house or there are no plastic windows, for every 3-5 sq.m. You can add one more section. If the thermal insulation of walls and roofs in the house is of high quality, neither through the windows nor through the door heat escapes, the number of sections can be reduced, but not more than 1 section for every 10 sq.m.

When calculating the number of radiator sections, make an error for the operation of the network and add another 25% to the unit of account.

Installation procedure:

1. Preparation of niches and openings for pipelines, radiators and boilers.
2. Laying of supply and return main lines. If necessary, heating the utility rooms, use collector distributors.
3. Installation of radiators. It is recommended to mount a foil material on the wall behind the radiator to improve heat dissipation.
4. Installation of all fasteners and distribution elements, after which the pipes are interconnected by means of fittings.
5. Final connection to the boiler (if natural circulation is selected) or to the pump and boiler (if forced).
6. Starting the coolant in the chosen way - natural or pumping.
7. Fill the system with coolant and leave for 1 hour. After this time, check all radiators and connections for any, even the most minimal, leaks.
8. Turn on the boiler at a minimum of 70 degrees and let the system warm up.
9. Again check the waterproofing and possible leaks.

If, at the end of the specified complex of work, the system is working properly - the pipes are heated, the temperature is maintained, and there are no leaks anywhere, the installation of the heating system has been successfully completed!
