HEAT, GAS SUPPLY AND BASICS OF VENTILASION

• Source - a place or thing from which something comes or can be obtained.
• To distribute - give shares of (something)
• Heating system - systems used to provide heat, especially to a building.

Heating systems

Classification of the heat supply system
Types of heat transfer

Heat supply is a system for providing heat to buildings and structures.

Heat supply is a system for providing heat to buildings and structures.

Any heating system consists of three main elements:

Heat source. This can be a thermal energy plant or a boiler house, or just a boiler located in a separate building.

Thermal energy

transportation system (heat networks).

Heat consumers.

Classification of the heat supply system

According to the location of the heat source, heat supply systems are divided into:

CENTRAL

LOCAL (they are also called decentralized).

Central heat supply
In a central heat supply system, the heat source is a thermal energy plant or boiler house that generates heat for a group of consumers: a quarter, a district of a city, or even an entire city.

Local heating systems
In local systems, the source of heat energy and its consumer are located in the same building or very close to each other.
Closed. With such a system, water from the water supply system is heated by a coolant and supplied to the consumer.
