Development of radiators through history
Improvement in the field of heating has been a challenge for people for a long time. However, the invention of the first radiator in 1834, which Denison Olmsted described as a heat exchanger furnace and used the term "radiator" in his patent, was a turning point in the field. This device made it possible to heat rooms by emitting heat.
Further development of radiators brought many innovations. In 1855, Franz San Galli invented a cast-iron radiator with a special valve control that was more efficient in emitting heat. Over time, new materials, shapes and methods of heat transfer appeared which contributed to improving the efficiency and functionality of radiators.
Radiators were made of various materials such as cast iron, steel, aluminum, and copper. Each material has its own advantages and properties that affect the efficiency and performance of radiators. In the beginning, cast iron radiators were popular because they had good heat retention, but they were heavy and took a long time to heat up. Steel radiators were lighter and heated up faster but had a lower heat capacity. Aluminum radiators appeared later and were distinguished by high thermal conductivity and the ability to quickly heat up. Copper radiators were just as efficient at transferring heat but were more expensive.
In addition to the materials, the shape of the radiators also changed. At first, radiators consisted of pipes and plates, but later panel radiators appeared with a larger heat emitting surface. Some radiators also had ribbed panels which increased their efficiency in emitting heat.
Radiators today
The development of radiators throughout history testifies to constant search and innovation in order to ensure efficient and comfortable heating of rooms. Today, radiators are not only functional, but also aesthetically attractive, which makes it possible to create a pleasant and comfortable living environment.
Today we know different types of radiators that adapt to the needs of different rooms and environments.
Classic cast iron radiators
Classic cast iron radiators are known for their durability and ability to retain heat even after the heating is turned off. They are heavier and take longer to reach the desired temperature, but once heated, they give off long-lasting heat. They are suitable for older buildings.
Steel radiators
Steel radiators are light and heat up quickly, but they don't retain heat as long as cast iron radiators. They are more flexible in terms of shapes and sizes and suitable for more modern spaces. Advantages include long-lasting heat output and high durability, but they are heavier and take longer to warm up.
Aluminum radiators
Aluminum radiators are lighter than cast iron and have good thermal conductivity. They heat up quickly and have high heat dissipation efficiency. They are popular in modern homes. One of the main disadvantages of aluminum radiators is their higher price compared to other heating options.
Panel radiators
Panel radiators consist of several thin panels that increase the surface area for radiating heat. This enables a more uniform heating of the room. Panel radiators are common in modern buildings. They enable uniform heating, a larger surface for emitting heat, but have a lower heat capacity.
