Some facts about water heating

Circulating hot water can be used for central heating.
Sometimes these systems are called hydronic heating systems.15 Common components of a central heating system using water-circulation include: A supply of fuel, electric power or district heating supply lines A Boiler (or a heat exchanger for district heating) which heats water in the system Pump to circulate the water Radiators which are wall-mounted panels through which the heated water passes in order to release heat into rooms. The circulating water systems use a closed loop; the same water is heated and then reheated. A sealed system provides a form of central heating in which the water used for heating circulates independently of the building's normal water supply. An expansion tank contains compressed gas, separated from the sealed-system water by a diaphragm. This allows for normal variations of pressure in the system.

A safety valve allows water to escape from the system when pressure becomes too high, and a valve can open to replenish water from the normal water supply if the pressure drops too low.

Sealed systems offer an alternative to open-vent systems, in which steam can escape from the system, and gets replaced from the building's water supply via a feed and central storage system. Heating systems in the United Kingdom and in other parts of Europe commonly combine the needs of space heating with domestic hot-water heating.
These systems occur less commonly in the USA.

In this case, the heated water in a sealed system flows through a heat exchanger in a hot-water tank or hot-water cylinder where it heats water from the regular potable water supply for use at hot-water taps or appliances such as washing machines or dishwashers.Źródło: https://en.wikipedia.org/wiki/Central_heating

History of central heating

The ancient Greeks originally developed central heating.

The Temple of Ephesus was heated by Flues planted in the ground and circulating the heat which was generated by fire.

Some buildings in the Roman Empire used central heating systems, conducting air heated by furnaces through empty spaces under the floors and out of pipes in the walls?a system known as a hypocaust.23 The Roman hypocaust continued to be used on a smaller scale during late Antiquity and by the Umayyad caliphate, while later Muslim builders employed a simpler system of underfloor pipes.4 After the collapse of the Roman Empire, overwhelmingly across Europe, heating reverted to more primitive fireplaces for almost a thousand years. In the early medieval Alpine upland, a simpler central heating system where heat travelled through underfloor channels from the furnace room replaced the Roman hypocaust at some places.

In Reichenau Abbey a network of interconnected underfloor channels heated the 300 m? large assembly room of the monks during the winter months.
The degree of efficiency of the system has been calculated at 90%.5 In the 13th century, the Cistercian monks revived central heating in Christian Europe using river diversions combined with indoor wood-fired furnaces.

The well-preserved Royal Monastery of Our Lady of the Wheel (founded 1202) on the Ebro River in the Aragon region of Spain provides an excellent example of such an application. Źródło: https://en.wikipedia.org/wiki/Central_heating

Is it worth it to repair a broken pipe yourself?

plumbing Harrow Self-repair is a way to get rid of the fault, which is used by many of us. Often it can be done very easily, but if they relate to the hydraulics, better be careful. It is not easy to replace a broken pipe or repair the faulty seal, because in this case a better choice would call good service hydraulic, who will do everything professional and efficient.
Such companies can now find almost everywhere, so instead undertake to repair the personal risk and higher costs, it is better to entrust this task good art.
It is they who fix everything as it should, without causing additional problems..
