Open. In an open heating system, water for DHW needs is taken directly from the heating network.
According to the method of connecting the hot water supply system, heat supply systems are divided into:

BY THE TYPE OF HEAT CARRIER USED

HEAT CARRIER
Water
Air
vapour

Types of heat transfer

• Heat transfer is a way of changing the internal energy of a body when energy is transferred from one part of the body to another or from one body to another without doing work.
• There are the following types of heat transfer: conduction, convection and radiation.

Types of heat transfer

Thermal conductivity is the process of transferring energy from one body to another or from one part of the body to another due to the thermal motion of particles.
Convection is a type of heat transfer in which energy is transferred by layers of liquid or gas.
The third type of heat transfer is radiation.

Heating systems of building

Water heating system.

Air heating system.

The heating system consists of a thermal energy source, a pipeline network and local heating devices. The source of thermal energy can be a centralized heat supply system from a thermal power plant or a quarterly boiler house, a local boiler house for one building or a small group of buildings.

The most common heating systems are:

• • Air heating system.
• • Water heating system.
• • Combined (mixed) heating system.

They all have their own specifics, so they are best suited to specific conditions. This makes it impossible to say which system is the best.

A water heating system is a complex of structural elements designed to receive, transfer and transmit the required amount of heat to heated rooms.
