Beautiful piping of the heating system. I explain what's the catch

For those who order the installation (piping) of the boiler room, the criterion for a well-done work is a geometrically beautiful system that pleases the eye. Well, of course, no leaks. As an example:

But, unfortunately, many do not understand hydraulics. This also applies to most specialists, even those who are experienced in their field. Their task is to bring the pipe from point A to point B. Make a branch from the pipe and everything so that it is beautiful, like the wiring of tracks on an electrical board, pleasing to the eye. The processes of turbulence and water hammer are not familiar to them.

At one time, when specialists changed radiators in my apartment, they welded jumpers very far from the radiators themselves. I have the last 10th floor, then at low pressure in the system (in autumn and spring), the water cannot push through even minimal airing and the radiators cease to normally give off heat, part of the sections becomes cold. We have to bleed air from the Mayevsky tap.

Examples of beautiful and expensive copper piping. But why was it not possible to raise the boiler higher and avoid stepped bends? Complex curves on the left give the system increased hydraulic resistance. Water can make noise in such nodes (if the circulation speed is increased in cold weather). Such angles in the pipes lead to the appearance of air bubbles from the dissolved gases in the coolant.

Here is another example, showed places where the flow of the coolant will be difficult, there will be increased hydraulic losses. After all, almost all of them can be solved if the system is drawn to scale, and then assembled according to the scheme. But the masters do it by eye, as he said, they lead the pipes from point A to point B, observing only one criterion: beauty.

Here, too, a specialist mounted extra knees in the system. This could have been avoided by moving the boiler to the right.

In a hydraulic sense, it is more correct to use metal-plastic pipes with smooth bends. In such a layout, there is no hydraulic resistance in sharp bends.

I agree that there are installation schemes where bends and bends cannot be dispensed with. But they can be done not immediately at 90 degrees, but smooth, by a set of two fittings 45 g each:

The sewage system is installed according to a similar principle. They recommend not to use sharp turns immediately under 90 degrees, but to dial two out of 45 degrees. Do you know why such techniques are rarely used by specialists in the installation of heating systems? This adds work: more elements to be mounted, more risk of leakage.

With a weak circulation of the coolant, nothing is heard. But no one calculated how much energy is lost in such nodes and how this affects the load on the circulation pump. Maybe if you exclude a few dozen of such bends and the electricity costs for the operation of the pumps will be reduced?

If I'm wrong about something, you can write about it in the comments.
