Coolant circulation is the process of moving a coolant (liquid or gas) in a heating, cooling or hot water supply system to transfer and distribute thermal energy. Circulation ensures efficient use of heat, maintains a uniform temperature and promotes optimal functioning of the system. Coolant circulation: main features Types of circulation: Forced circulation: Based on the use of circulation pumps that create pressure and move the coolant […]

Forced circulation is the process of moving a coolant (liquid or gas) in a heating, cooling or water supply system using circulation pumps. Unlike gravity circulation, where the coolant moves naturally due to the difference in density between the hot and cold substances, forced circulation requires the active intervention of the pump to create pressure and ensure a constant flow of coolant through the system. […]

Gravity circulation is the process of natural movement of a heat carrier (liquid or gas) in a heating or cooling system, based on the difference in density of the hot and cold substance. In this case, the hot heat carrier, having a lower density, rises up, and the cold one, with a higher density, goes down, creating a natural flow in the system without the need for mechanical pumps. Main characteristics: Operating principle: Thermal […]

Heating system balancing (calibration) is the process of adjusting the heating system to ensure uniform heat distribution across all radiators or convectors in the building, regardless of their location or distance from the heat source. This allows for optimum comfort and efficiency of the system, preventing overheating or underheating of different zones. Heating system balancing: key aspects The purpose […]

Thermal gradient in heating systems is the change in temperature of the coolant or air in the space of the heating system. This gradient measures the difference in temperature between different points in the system, such as the inlet and outlet of a heat exchanger, radiator or other element of the heating system. Thermal gradient in heating systems: main aspects: Definition: Thermal gradient: This is the difference in temperature between two points in the system […]

A wet rotor circulation pump is a type of pump used in heating and water supply systems in which the rotor and bearings are in contact with the circulating coolant or liquid. Wet rotor circulation pump: main aspects: Construction: Wet rotor: In this pump, the rotor and bearings are immersed in the liquid, which ensures their lubrication and cooling. This is distinguished […]

A dry rotor circulator pump is a type of pump used in heating, plumbing and air conditioning systems in which the rotor and bearings are located outside the flow of the circulating fluid and are cooled in a separate way. Dry rotor circulator pump: main aspects Construction: Dry rotor: In this pump, the rotor and bearings are in a separate chamber that is not in contact with the liquid, which […]

A boiler air cleaning system is a system designed to automatically remove soot, ash and other contaminants from the boiler heat exchanger using air flow. It ensures regular and effective cleaning of the boiler, which helps maintain its performance and extend its service life. Boiler air cleaning system: main aspects Operating principle: Air flow: The boiler air cleaning system uses compressed air to […]

Deaeration systems in heating systems are devices and methods designed to remove air and gases from the coolant in the heating system. The purpose of deaeration is to prevent the formation of air locks and corrosion, improve the efficiency of the system and extend the service life of the equipment. Deaeration systems: main aspects Operating principle: Air removal: Deaeration includes processes that allow air dissolved in […]

A two-pipe heating system is a type of heating system that uses two independent pipes to circulate the coolant: one to supply hot coolant to the heating devices, and the other to return the cooled coolant back to the boiler or heat source. Two-pipe heating system: main aspects: Operating principle: Supply circuit: Hot coolant (water or other liquid coolant) enters […]
