About water central 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.
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.
range of hydraulic works in a block
Plumbers working in a cooperative housing standard working hours from eight hours to the seventeenth or eighteenth. In such a time they can also perform plumbing work in a block of flats. More work done in a block must be well organized in such a way that it can be performed as soon as possible with the greatest respect for the rights of the people to preserve their privacy and quiet in the early morning. The tasks of the executives of the association must also ensure the safety of residents of the block during the works. They can apply to do the second division of water, clean water and sewage network or even replacement of water meters in all areas.
checking water meters
Plumbers employed by the cooperative to perform a variety of hydraulic works. These include repairs done in individual apartments on request of their owners and renovations carried out throughout the block. Usually in all apartments at the same time they are installed new water meters, corresponding to accepted standards. Plumbers make the readings of the counters and check whether they function correctly and that none of the residents of the block is not he cheat on by their counter just to get lower bills for water consumption. They deal with the replacement of defective meters with new ones, if you notice the occurrence of any irregularities in their operation.
