The history of heating systems dates back to ancient Rome. It was time when channels networks were laid in the walls and under the floor to pass hot air. So that it was possible to heat a large area in the palace or the whole house with only one furnace.
Over time and the development of engineering technologies, systems have been modernized. In the Middle Ages, air heating was actively used, as well as the stone property to retain and give off heat for a long time.
In the XIX century, several technological breakthroughs took place:
- Bank of England Governor John Horley Palmer introduced a steam heating system in his home. This made it possible to grow grapes in the cool climate of Britain.
- The German businessman Franz San Gali who lived and worked in St. Petersburg, invented the first cast-iron radiator. A large-format heater was called the “hot box” and quickly gained popularity in Europe and the USA.
- 1890s. The market of North America and Europe was conquered by the manufacturer from the USA called American Radiator Company who proposed a more economical and compact model of a cast-iron radiator. During ten years several factories were opened in Europe.
Systems based on networks with cast-iron heating devices remained symbols of warmth and comfort throughout the first half of the 20th century, until radiators made of other metals entered the foreground.
Steel radiators: from tubular to panel devices
The era of steel batteries which have a number of advantages over bimetallic radiators and devices made of other metals, was launched by Swiss engineer Robert Sender.
The inventor was the son of the founder of the mechanical repair shop Jacob Sender, which was transformed into an enterprise for the production of light motorcycles since 1923. Jacob had seven sons and each had his own role in the family business.
However, in 1930 the Senders brothers were forced to look for new opportunities to apply their engineering skills. Robert was one of them who was offered to make cast-iron radiators.
Sender had no such experience, so the engineer decided to make steel pipes the basis of the heating radiator. In the manufacture of motorcycles, they were collected in a register and used to cool the engine.
Robert Sender thought that the reverse process of tubes heating was absolutely possible. The invention was patented in October 1930, the brothers founded a new enterprise and became the first European manufacturers of steel radiators. The novelty quickly attracted attention:
- solid, but lightweight construction,
- fast heating and high heat dissipation,
- operation under high pressure.
Also, steel radiators initially were larger than cast-iron devices. They were compact and aesthetically pleasing. Features were appreciated by architects and builders.
In the middle of the twentieth century production of steel panel radiators began at once at several enterprises in Europe. Heating devices of this type quickly conquered the market by even greater compactness, heat dissipation and ease of use.
What is happening now
Economic stagnation of the 70s when Europeans were looking for ways to reduce the cost of heat supply led to the greater success of steel radiators. By the end of the century, the environmental friendliness of heating systems along with energy efficiency came to the fore. Steel panel radiators proved to be a competitive product even in this market.
Today, 90% of the heating market in Europe falls on steel batteries. In countries of Eastern Europe and the CIS, where there is a large-scale transition to energy-saving technologies, the sales market is growing from year to year.
Benefits of inexpensive, high-quality and technological products were appreciated in South-East Asia, the most dynamically developing economic region in the world. Radiators of this type are popular in North America, where there are many private houses and autonomous heat supply is very well developed.
Operational characteristics allow installing panel radiators in rooms of any type. Including, with special hygiene requirements – up to hospitals and operating rooms of hospitals.
This provides wide opportunities for the successful distribution of products and the formation of proposals beneficial to the end user.
