Boiler Repair Earlsfield offers repair and maintenance of Earlsfield heating installations. The principle of operation of gravity heating is based on the use of the phenomenon of water density change caused by a change in its temperature. Gravity heating can be performed with a lower and upper distribution. Pipes distributing hot water in heating with lower distribution are led in the basement of the building and from them another part of the installation is led to the rooms on the upper floors. In heating with upper distribution, the main pipe of the installation carries hot water to the attic, from where it is distributed throughout the building. Gravity heating is used in buildings where the horizontal distance from the heat source to the farthest riser does not exceed 25 m, and the height difference between the heat source and the lowest radiator is at least 2 m.
