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.
Advantages of heating bath
The scope of modern services hydraulic assembly includes a heated bath tub or shower tray, where you can easily bathe a child or carry out a quick toilet without entering the shower. Still a lot of people looking for good ways of heating the water in the bathtub, serving ago, not to have to constantly pour into the hot water during the long bath. One of them is the installation of a hot tub or jacuzzi. This type of bathtub must have good flow, so that they can function efficiently and not caused problems. The advantage of this type of tub is that it can take them a long bath and enjoy her during a massage, which has relaxing and therapeutic properties.
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. (In North America the term "furnace" is normally used if the purpose is not actually to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications,12 including water heating, central heating, boiler-based power generation, cooking, and sanitation.
