And then even today: Buying and storing fuel
Summer has always been a necessity for many owners of solid fuel boilers to order the coal and its composition to a designated place in the cellar. Coal was also common in the towns, and in flats most of the rooms were in every room. While most city houses already use central gas or district heating, solid fuel boilers find use mainly in family houses or in companies. But the summer was the best time to buy solid fuels. This is especially true for wood pellets, which you will get much cheaper in the summer than before and during winter.
Radiators and their condition
The first cast iron hot water radiators appeared in the second half of the 19th century in the United States. In our country they began to be used for up to a few decades later. At that time it was a technological novel that was used mainly in magnificent villas, and the inhabitants of ordinary apartment buildings still had to settle for ordinary coal-fired stoves. The principle of the hot-water radiator has not changed since then. It is still a metal body with a large surface that transmits the heat of the heating water to the surrounding air. However, old cast iron radiators are often replaced by low-temperature radiators designed for use with modern condensing boilers. Radiators do not need too much maintenance, only check them during the summer for corrosion and leakage. In that case, ensure that they are repaired.
Heating regulation earlier and today
The first central heating systems were used as a heat transfer medium for steam. With steam heating, the well-known Scottish physicist and inventor James Watt began experimenting in the eighteenth century. However, the real possibilities of regulation of steam and hot-water heating came to its great development in the period after the First World War, when hot water heating systems began to appear more with the regulation of the output of the heat source. At present, heating control options are very wide. "For example, the use of an equithermal heating control is often used, where the output of the heat source is controlled by the ambient air temperature. With district heating, standard thermostatic heads are already standard. They can also be digital with the possibility to set the radiator temperature in time, " explains modern trends in heating control by Roman Švantner (ENBRA). Even thermostatic heads is good to pay little attention in the summer. During the summer outage of the heater, keep it open to the maximum and turn it once in a while .
What people did not do before: Emissions and booth inspections
Modern times brought some unprecedented news in the area of heating. One of them is the emphasis on emissions and environmentally friendly boiler operation. While the big cities used to cope with large air pollution due to coal heating in the winter, these problems continue to persist mainly in small towns and villages. The conditions for boiler operation are increasingly tightened in relation to emissions. "From January 2018, it will only be possible to sell solid fuel boilers meeting the strict conditions of the 4th and 5th emission classes. The 1st and 2nd Emission Class boilers, most of the old solid fuel boilers, will not be able to run at all since 2022 , " says Roman Švantner , Legislation on Boiler Emissions. The regular function of modern boilers is also related to regular maintenance. Manufacturers recommend that the boiler should be inspected by a service technician at least once a year. But do not leave this tour until autumn, when it is difficult to get the right expert.
