Heating the dwelling and cooking food requires the presence of a hearth in the house in which it is necessary to maintain fire. So it was until the man invented the gas pipeline, and with it became possible to operate gas stoves, boilers and boilers. The original models of boilers were used not only for heating, but also for cooking. They worked on the simplest form of fuel - solid. The degree of combustion at it leaves much to be desired, as a result quickly accumulated ash and soot. This led to the fact that often had to clean the boiler, throwing away the ashes. But to leave such a boiler for a long time without supervision, no one dared, because it was extremely dangerous. But with the advent of gas boilers in the market, everything began to change for the better.
The use of gaseous fuels has virtually eliminated the problem of poor combustion of fuel, although boilers still need regular cleaning. Also modern boilers are absolutely safe, and advanced models have the functions of delayed start and control of fuel consumption and temperature. It is even possible to set a specific program, thanks to which the boiler will regulate the temperature depending on the time of the day and the season. In spite of all its adaptability, modern and earlier versions of gas boilers need gas. Until recently, only metal pipes were used to supply gas to the boiler. This did not allow the boiler to be moved depending on the needs of the consumer. Now in the market a lot of flexible hoses for gas are available. Such gas hoses are made of various materials, but gas, PVC hoses are the most profitable for durability, price and safety. They withstand temperature changes from -20 to +60 degrees Celsius, the working pressure in them is 7 atmospheres, and the maximum is 30 atmospheres. Also, additional advantages are low price, high flexibility, aging resistance and immunity to wandering currents.
