Radiator (definition)

Radiator — is a device for transferring heat from a coolant to the surrounding space, used in heating systems to heat rooms. As a rule, they consist of metal sections or panels that effectively transfer heat from hot water or steam circulating inside them to the air in the room.

Radiator: main components and operating principle

1. Frame - usually made of materials with high thermal conductivity, such as cast iron, steel or aluminum. These materials allow efficient transfer of heat from the coolant to the air.
2. Sections or panels — may consist of separate sections that can be added or removed to adjust the power, or be in the form of solid panels. Sectional types are most often made of cast iron, and panel types are made of steel.
3. Coolant inlet and outlet — the radiators have pipes for connection to the heating system. The hot coolant enters the radiator through the inlet pipe, circulates inside it and gives off heat, then the cooled coolant exits through the outlet pipe.
4. Edges or additional surfaces — to increase the heat transfer area, radiators can have fins or additional surfaces, which increases their efficiency.

Features and Benefits:

• Efficient space heating — ensure uniform distribution of heat throughout the entire area of the room, creating comfortable conditions for living or working.
• Temperature adjustment — modern radiators are equipped with thermostatic valves that allow you to regulate the temperature in the room, maintaining a given level of comfort and saving energy.
• Durability and reliability — radiators, especially cast iron, have high strength and durability, are resistant to corrosion and mechanical damage.

Application:

Used in central and individual heating systems of residential, commercial and industrial buildings. They can be installed in various premises, from living rooms and offices to production workshops and public buildings.

Types of heating batteries:

• Cast iron — have high heat capacity and a long service life, are suitable for systems with high temperatures and pressures, as well as for systems with a cooling boiler, giving off heat to the rooms for a long time by heating the metal.
• Steel panel — have less weight and heat up quickly, they are easy to install and adjust.
• Aluminum — characterized by high thermal conductivity and lightness, suitable for systems with low and medium temperatures.
• Bimetallic — today these are the most modern and efficient radiators, which provide efficient operation in gravity and fully adjustable heating systems. Due to the combination of metals, they have higher thermal conductivity, cool down slowly and at the same time heat up quickly with adjustable heating.

Batteries are an important element of heating systems, providing efficient and reliable heating of premises in a variety of conditions. In systems with pellet boilers, it is better to use bimetallic or aluminum radiators, since a system with fine adjustment is installed. With appropriate installation of heating circuits pellet boiler with an installed microcontroller can control the temperature of batteries and air in rooms with fuel savings. This distinguishes pellet technology from conventional solid fuel, in which part thermal energy it is necessary to accumulate or take into account the useless fuel consumption.

For air heating

Water heating can be implemented as air-water heating. We are talking about a water-cooled model with a fan that improves air circulation. This solution is used in floor radiators, providing high-temperature bottom heating of the room.
