Let the water run in a straight line: advantages of serial connection of heating radiators, diagram and recommendations

Serial connection of radiators - the most popular and economical option heating of the room, thanks to which an autonomous heating system is created, independent of the central one.

Necessary tools

To form such a connection of heating devices, the following components are required:

• Pipes: for the main line, it is advisable to choose a pipeline made of steel, galvanized steel or metal-plastic with the appropriate diameters of 2.2 cm, 2.2 cm and 2.6 cm. Polypropylene pipes are also allowed for use, but not in a system with three or more radiators. The branch pipes coming off the main line are made of the same materials, but have smaller diameters.

• Radiators: the choice of the necessary equipment is based on personal preferences and expert advice. For such a scheme the most optimal counts 5 batteries, and for a larger number of them, a well-calculated project is required.
• Thread sealing tapes on batteries.
• Thermostatic valves to regulate the heating of radiators.
• Fitting for connecting pipes together.

The direct components are also expansion tank and heating boiler.

Preparatory actions

Before starting the process a detailed project is calculated heating systems for each specific room.

Then it is selected one of the options serial connection: horizontal or vertical, depending on the characteristics of the living space and personal preferences.

Then, based on the selected type of scheme, It is necessary to decide on the coolant. For vertical decoupling, it is better to use antifreeze diluted in water, and for horizontal decoupling, use regular water.

How to connect two heating radiators, diagram

1. Initially, when connected in series The location of the heating boiler is determined. It is usually located in the basement on a special fire platform. An expansion tank is firmly fixed above it.

2. At the same time a competent chimney setup is being thought out: the draft must be sufficient, and the smoke itself must go outside without remaining inside the room.
3. After that it is produced connection of the main pipelineIt is important to avoid bends when laying.
4. There is a circle around the perimeter of the entire house a pipe parallel to which all the batteries are connected.

7. And it is also necessary provide an element through which the system will be filled water and draining it.
8. In a series connection diagram, can be supplemented with taps and thermostats each battery.

With vertical strapping a circulation pump is included in the circuit for forced circulation of the coolant, and when horizontal — a slope is created in the feed pipe, and a Mayevsky valve is installed in front of each radiator to remove excess air from the system.

Pros and cons of connecting batteries in series

Pros serial connection:

• low cost consumables;
• allowed use of any kind radiators;
• if necessary the pipeline is fed into the "warm floor";
• coverage of the entire perimeter with heating devices rooms;
• easy installation;
• small amount of consumable material.

Cons:

• complex design process;
• high heat loss coefficient: due to the characteristic elongation of such a line, the coolant cools down towards the end;
• in the absence of a circulation pump, stagnation occurs liquid moving through radiators and a decrease in the efficiency of the system as a whole;
• in the absence of thermostats on batteries - lack of control above the heat supply.

Help from professionals

When connecting radiators in series it is necessary to consult with specialists in terms of developing a full-fledged project. To avoid various types of miscalculations, it is recommended to entrust them with the management of this process on a turnkey basis.
