Heating system
The heat carrier is hot water or antifreeze Through the pipeline system, the heat carrier is supplied to radiators or batteries that perform a heating function As a result, heated radiators and batteries warm up the air in the room and thus, the air temperature rises
When cooling down, the coolant returns to the boiler, where it warms up again and repeats its path to the radiators Thus, the heating cycle is presented in the simplest form In a well-designed heating system, the coolant goes a long way before getting into the radiator and back into the boiler
In modern systems the heat carrier comes from large industrial type boilers If we talk about private houses and cottages, the heat carrier is heated in the boiler By converting electricity or fuel (firewood, gas, coal, etc)
Wiring diagrams-considering possible options
Depending on the heating system chosen by the consumer, the pipe layout will depend There are two types in total:
- Wiring with natural circulation (open type);
- Forced circulation (closed type)
In this case, the heating devices will be connected according to a well-developed scheme In total, there are several types of wiring – one-pipe and two-pipe, as well as vertical and horizontal
Heating system with one pipe and forced circulation
In systems with forced circulation of the heat carrier, the" circulation " of the liquid is carried out by means of a circulation pump Thanks to this device, you can heat a lot more rooms In this system, there is an expansion tank of the balloon type, inside which there is compressed air, which is fixed there by a membrane
In systems of this type the coolant is under regular pressure and does not contact the air masses During the working process, the temperature and pressure are constantly falling and rising That is why this type of system is equipped with safety devices Here are the air vents, discharge valves and pressure gauge
Single-tube systems with manifolds and circulation pump
This system is ideal for 2 or more storey buildings – despite the increased consumption of pipes and many connections, it has a huge number of advantages This system will help to heat any building, regardless of its architecture Here you can make wiring from pipes of any diameter, which can be hidden under the floor or hidden in a monolith The only disadvantage of such systems is increased power consumption
Two-pipe system with collectors and forced circulation system
This option, in terms of design, is considered the most popular and effective All thanks to the fact that you can independently adjust the temperature regime here Each radiator is connected to the system separately – for this purpose, metal-plastic pipes are used
An Autonomous closed system is attractive for the following reasons:
- The expansion tank can be installed next to the boiler, rather than at the highest point;
- In systems of this type, the coolant does not contact the air, which prevents all sorts of processes and chemical reactions that negatively affect the condition of the pipeline (rust, oxidation, etcp);
- The drain valve will help you quickly get rid of air jams and overpressure without the intervention of the system owner
Boilers, or heat generators, play a key role in the entire system Boilers, as well as systems, are of two types – single-circuit and double-circuit
The difference between them is as follows:
- Single-circuit boilers can work either in the heating system, or provide the building with hot water;
- Two-circuit structures perform both of these functions
The choice of boiler depends largely on the type of fuel used If you bet on liquid fuel or gas boilers, you will get a model that is fully automated and requires only seasonal prevention Solid fuel models will have to constantly load fuel and constantly clean the chimney
Electric models are the most affordable and popular option on the market The only drawback is that you will need to conduct special wiring for such a boiler, as well as get permission to install it from utilities Please note that electricity costs will increase significantly
Boiler capacity-the main parameter of aggregates, on the basis of which other nodes and connections are selected, determines the diameter of pipes
