Connection diagram of a double-circuit boiler: what should be the piping, its features

Indeed, the connection and installation of a double-circuit boiler can be done independently. It is important to adhere to certain requirements and remember that the approach to each device is considered individual. All possible features of the connection circuit of a double-circuit boiler will be described later in the article.

How to connect a double-circuit boiler correctly

How to do the binding of a double-circuit wall-mounted heating boiler with your own hands? First you need to understand what the principle of operation of the presented design is. Efficiency is carried out due to two circuits that do not affect each other in any way.

They are both responsible for the correct operation of the coolant. Only one of them guarantees a product without interruptions in the heating system, and the other provides the same, but in the hot water system.

Connecting a double-circuit boiler is quite simple. The first step is to hang the unit on the wall. Next, you will need special brackets, which are usually supplied with heating equipment.

This is done using self-tapping screws and plastic dowels. And also, to install them, you need to arm yourself with a building level and a plumb line. Thanks to them, it will be possible to make the connection exactly in a horizontal line.

As you can see, there is nothing complicated in this, therefore the final step - to hang the boiler itself on the fastener products, is not difficult. And all that remains to be done in the future is to connect it with the necessary details, purchase a chimney and bring it to the network.

What should be the piping of a double-circuit wall boiler

In order to avoid maximum pressure indicators, it is worthwhile to pre-secure the device from blockages, make the correct piping. The best option will depend on the type and model of the boiler.

Features piping double-circuit boiler with indirect heating boiler

The situation is considered ideal when the layout of the double-circuit heating boiler is such that the boiler is installed with the boiler, and not in an existing system. During installation, it is advisable to adhere to the following rules:

The surface that is selected for installation should be as flat as possible;
The location of the additional element should be chosen close to the central structure, as well as to ensure accessibility;
Insert filters to equip yourself with the best water quality;
For long-term operation it is necessary to supply all the circuits on a ball valve.

And so that functioning takes place at the highest level, it is recommended to include in the harness:

Pumps to improve circulation;
A filter system or a sump to clean cold water;
Check valve to prevent movement in the opposite direction;
Three-way mixing valve to prevent excess fluid from entering;
Two-way thermostat;
With a large flow of hot water, you can purchase an additional flow-through heat exchanger.

Tying a double-circuit boiler with polypropylene heating

In the piping layout of a double-circuit boiler for heating with polypropylene, it is best to use a collector and hydraulic arrows. In this case, you can not resort to the use of metal pipes of considerable length, since the liquid rarely reaches indicators from 70 to 80 degrees of heat. For each circuit, a circuit with circulation equipment should be performed.

This is necessary to guarantee safety and reliability. In this case, the main load will fall on the auxiliary pumps when pumping the coolant. In a place where cold water is supplied, it is advisable to mount filters to supply both fine and rough cleaning.
