Double-walled storage tank plumbing

As you know, the engine room consists of various equipment such as a boiler, burner, source, etc., by connecting these components and connecting it to the building's plumbing network, a central heating system is created. The equipment that we will discuss in this article is a double-walled source that is used to store and supply the building's consumer and sanitary hot springs in the engine room. In the following, we will get acquainted with how to pipe a double-walled source in a principled and standard way, stay tuned.

The correct method of double-walled source piping

The image below is a double-walled source on which we have used numbers to determine the connection points of the source to the piping system. In the following, we explain the reason for the location of the source connection points in the specified place.

In the picture above, the numbers 1, 2 and 5 indicate the inlets and outlets of the inner wall, and the numbers 3 and 4 indicate the inlet and outlet of the hot water of the engine room system in the outer wall.

Inlet of cold water consumption

As you know, cold water is heavier than hot water due to its temperature and is lower. For this reason, the inlet of cold water consumption (No. 1) that enters the double-walled source for heating is better to be considered below the inner wall of the source.

Consumption of hot water consumption

Consumption water entering the double-walled source is heated by the circulation of hot water from the boiler or boiler inside the outer wall (on the inner wall) and enters the building's piping network. Because the heat exchange between the hot water of the heating system and the cold water is better, it makes sense to consider the hot water outlet above the source and in the opposite direction to the water inlet to provide enough time for heat exchange. In the schematic picture above, you can see point number 1 (cold water inlet) and point number 2 (hot water outlet).

Hot water inlet boiler

Point 3 indicates the hot water inlet of the heating system, which is located above the double-walled source due to the effective heat exchange and in the direction where the hot water outlet pipe is connected. In general, the water sent by the boiler or boiler has the highest temperature when entering the double-walled source and loses some of its heat due to heat exchange with the cold water consumed inside the inner wall of the source. For this reason, it is better to place the hot water inlet of the heating system at the closest point to the hot water outlet.

The cooled water outlet of the boiler or boiler

Point 4 is the water outlet of the heating system, which loses its heat and becomes lukewarm after heat exchange. The cooled water is discharged through this outlet and directed to the boiler or boiler for reheating.

Return of hot water consumption

On both sides of the double-walled source, there are two inlets for the return of hot water consumption, which are indicated by the number 5. Consumed hot water that is not used in the building loses its heat and cools if it is stagnant, so it is redirected to a double-walled source for heating by a small linear pump that circulates the sanitary hot water. This also saves on hot water consumption, because when the hot water tap is opened, some of the water inside the pipes is wasted if it is cold, and water consumption increases, but with a constant circulation of hot water in the source and pipe network. The building drains as soon as the hot water tap opens.
It should be noted that only one of the points intended for the return of hot water to the double-walled source is used, and if the return water pipe is connected to each, the other point will be covered with a cap. Connecting the hot water return pipe to the double-walled source should be in the direction of cold water entering the source.
