Winter arrives, with the expected cold weather, and our thoughts turn to hot teas to drink, Christmas, weekend skiing, hugs and evenings on the sofa watching a movie with your partner embraced. Less romantically the thought also goes toheating system scheme because we wonder how efficient it will be and how much it will ensure that we can enjoy a nice warmth in our home. This is one of those topics classically snubbed by many, especially when it's not cold and you don't feel compelled to think about a topic so little appeal. Yet when the temperatures drop, at least you need to know how a heating system is composed, at least in yours essential parts. Do you know them? Let's try to see them together, without pretending to become experts in the field because fortunately there are those who take care of them for work.

Regardless of the type, each heating system consists of a heat generator, by the heating terminals and pipes, by a regulation system and metering and various other devices, different according to the type of generator and terminals used.

Let's see briefly how they are connected in a hypothetical and simplified heating system scheme. The heat generator, often consisting of a boiler, can be powered by a liquid fuel or even by a gas, the heat transfer fluid obtained is then transported by the pipes to the delivery terminals to emit the necessary heat in every single room of the house.

This is it heating system scheme to which then in 90% of cases are added various and any systems that allow you to program and manage the system. Thermostats are among the most frequently installed and are also used to understand how much is being consumed.

Heating system diagram: types

Regardless of the type of system to be adopted, the aim must always be to create or maintain the conditions of wellness and thermal comfort during the cold season. However, it is useful to know that there are three different types of heating systems from which we can choose, they are three very general categories, each has various sub-categories but those are the talk of technicians. We stick to the three macro categories represented by centralized systems, autonomous ones and district heating.

In the latter, the production of heat occurs at a great distance from the users, to which it is distributed through a special transport network. Often to the heat production it is accompanied by that of electricity and we talk about cogeneration.

Autonomous plants are simply single-family thermal systems a single housing unit while the centralized ones produce the heat necessary to heat an entire building or residential complex, have a higher overall efficiency than the autonomous ones, theoretically leading to greater overall energy savings. This has a price, however: with the centralized systems it is not possible to carry out a personalized management of the system.

Heating system diagram: elements

We have listed the elements present in one heating system scheme, let's observe the main features.

We said that i heat generators most often it is simply boilers. A fuel is inserted into them which reacts with oxygen, triggering a chemical oxidation reaction. It is precisely in this way that heat and the classics are produced combustion gas, nothing but the boiler fumes expelled from the flue. There are two types of generators, the more traditional, wall-mounted or ground-mounted, and condensing ones with higher yields.

Let's move on to the pipes that look different when the heat transfer fluid used. There are for example hot water systems with natural or forced circulation, steam systems and hot air systems. Hot water ones with forced circulation they are the most common in our homes and can be classified according to the type of water distribution network.

There are single-pipe or two-pipe heating systems, which are better because they allow you to turn off an element without interrupting the operation of the entire system. There are also implants with coplanar manifolds which have fewer risers because all the heating elements in the same apartment are served by a horizontal network of thin copper pipes.

It is time to go and see what characteristics i have dispensing terminals, important elements within a heating system scheme. If once there were not many alternatives to radiators, today you can also choose systems that have wall, baseboard and floor terminals, perfect for distributing heat more evenly.

Heating system diagram: characteristics

The definition of one Heating system diagram it is not an operation suitable for do-it-yourself, to define all its characteristics, step by step, it is necessary to contact a qualified plumber who could also ask for the help of a plant engineer. Before starting work on a new house, or the complete renovation of a system, it is good to have already laid one in which the position and size of each element and each individual pipe have been established. This is an essential step to be dedicated with the utmost attention to ensure the proper functioning of the system but also the elimination of unnecessary waste!
