Connection diagrams of heating radiators in a private house:

When building or repairing, you have different ways to connect heating radiators in a private house, but, nevertheless, there are only two options for a general arrangement of the circuit, although there are many nuances here as well. These options are divided into the arrangement of either a single-pipe or two-pipe system, although it provides for the transfer of a contour to a heated floor system, collector heating, and the like.

But in order to understand this, you should stay with us and follow in reading further, where, among other things, we will show you the video in this article.

Types of contours

Briefly about boilers

Note. For any type of heating you need a source and in this case it can be a particular boiler. The choice of this unit depends, first of all, on the availability of energy in your home - electricity, gas, diesel or solid fuel.

• Electric boilers are subdivided into two types - TEN and electrode, and this depends on the method of heating the coolant in them, that is, the water in them can be heated either with the help of heating elements or with the help of electrodes. At the moment, we are not interested in the full characteristics of the units, but at the same time it can be said that the price of the electrode is much lower, but there is no possibility of connecting hot water. In total, electric boilers are quite economical and can operate on a network of? 220V or? 380V, depending on the size of the heated room (required power consumption).

• The most common are gas boilers., but they, too, are of two types - convection (traditional) and condensation (low-temperature) - their choice depends on the heating circuit installed in the house. Condensation boilers are very expensive, but very economical - their efficiency sometimes exceeds 120%, but their use is most appropriate for low-temperature circuits, that is, underfloor heating systems. In cases with radiator or mixed (radiators - heated floor), as a rule, use traditional units.
• Less common diesel boilers - they are one-, two- and three-stage, and they are used most often in various farms, with limited access to power sources, such as electricity, gas and solid fuel. But solid fuel boilers are quite popular, especially since recently a lot of gas generator models working on the pyrolysis principle have been thrown onto the market.

Note. There are also universal boilers that simultaneously combine several types of fuel. For example, gas - electricity, gas - diesel, solar - gas - solid fuel and other combinations.

Heating circuit systems

Some plumbers use a radiator connection in a private house. Leningradka is a one-pipe system, usually designed for three or four, on the strength of five radiators (much depends on their size).

The essence here is as follows - the coolant, acting on a wider pipe, falls into small branches that feed the heating radiators - this is clearly seen in the upper schematic image.

The main problem of such a circuit is that when water enters the battery, it loses some of the temperature and goes back into the supply pipe and the further it gets, the colder it turns out.

In order for the cooling to not be so significant, a bypass is inserted in front of the radiator - in the upper photo it is made with stop valves and such a device is a scourge of multi-storey buildings for plumbers.

The fact is that the tenants, in order to raise the temperature in their apartment, block the bypass and the water circulates through their radiator, using the heat resource to the maximum, and the tenants who live farther get the already cooled coolant. It happens that the faucet on the bypass of the one-pipe heating system is installed on the first, second and third floor, then the inhabitants of the fourth, and especially the fifth floor, have almost cold batteries.

We continue to consider how to connect a heating radiator in a private house and proceed to a two-pipe contour, which is necessarily used in rooms with a large area - you yourself just made sure that, despite the savings, the one-pipe system has a number of drawbacks.

The main advantage of the system consisting of two pipes - supply and return (“return”) is that the coolant, passing through a large number of radiators on all floors, does not return to the supply pipe, but is discharged into the “return”.

The manual also allows you to simultaneously connect radiators with a warm floor to the two-pipe contour, as shown in the upper image - everything is also simple here, if you follow carefully.

The coolant moving through the supply pipe enters the radiators and the floor heating system, but it can only pass through the three-way valve, which is indicated in the upper circuit as a pumping and mixing unit (if necessary, a circulating pump can also be inserted) .

When the floor is heated to the desired temperature, the valve is activated and hot water is discharged into the return pipe, and when it cools down, the valve opens.

Conclusion

As you can see, the options for connecting heating radiators in a private house with their own hands are not so difficult - they just need to understand. But if you want to save and install a single-pipe system, then first calculate the required thermal power for the house - remember that one pipe without loss can heat a maximum of four bimetallic radiators for 10 sections.
