The first attempts to create central heating systems were made in antiquity /one of these systems was discovered by archaeologists during the excavation of Ephesus/. However, officially the creator of the radiator is considered Franz San Galli, German industrialist who emigrated to Russia in 1843 and patented his invention in 1855 in St. Petersburg. Perhaps it was the cool, northern climate that directed the interests of the engineer. Built in the mid-nineteenth century, the radiator functioned thanks to compressed water vapor circulating in the system of pipes and cast-iron radiators – this basic idea has remained unchanged to this day. San Galli called the invention “hot box” and produces the first radiators under the name “batteries”, which is still used in Russian as a synonym for radiators. Patented in Germany and the United States, the product quickly spread around the world.
In 165 years, radiators have undergone significant transformations. Modern radiators have acquired decorative shapes and new features, and today they to a small extent resemble the prototypes of the nineteenth century, but retro radiators are still in vogue.

Interesting fact – in 2005, on the occasion of the 150th anniversary of the invention, a 2-meter monument representing a cast iron radiator and a cat enjoying its warmth was unveiled in front of the thermal plant in Samara, Russia
