Mandatory hydraulic works carried out in the block
When a residential building administrators will notice that there is a need for its repair hydraulic, then join the collection of funds needed for this purpose. They may come from the so-called. repair fund or will temporarily raise the rent. Before joining the fundraiser will have to obtain the consent of residents to take such steps. They perform, so you need a vote on one of the meetings with residents and cooperative will be able to proceed with the execution of the repair only after obtaining the consent of the majority population. Residents who do not give their consent for the renovation will be excluded from it. However, mandatory will be carried out such plumbing, which will serve to prevent the creation of a large block of water leakage.
Hot water in central heating
Early hot water systems were used in Russia for central heating of the Summer Palace (1710?1714) of Peter the Great in Saint Petersburg. Slightly later, in 1716, came the first use of water in Sweden to distribute heating in buildings. M?rten Triewald, a Swedish engineer, used this method for a greenhouse at Newcastle upon Tyne. Jean Simon Bonnemain (1743?1830), a French architect, introduced the technique to industry on a cooperative, at Château du P?cq, near Paris.
However, these scattered attempts were isolated and mainly confined in their application to greenhouses. Tredgold originally dismissed its use as impractical, but changed his mind in 1836, when the technology went into a phase of rapid development.
Early systems had used low pressure water systems, which required very large pipes. One of the first modern hot water central heating systems to remedy this deficiency were installed by Angier March Perkins in London in the 1830s. At that time central heating was coming into fashion in Britain, with steam or hot air systems generally being used.
Perkins' 1832 apparatus distributed water at 200 degrees Celsius (392 °F) through small diameter pipes at high pressure. A crucial invention to make the system viable was the thread screwed joint, that allowed the joint between the pipes to bear a similar pressure to the pipe itself. He also separated the boiler from the heat source to reduce the risk of explosion. The first unit was installed in the home of Governor of the Bank of England John Horsley Palmer so that he could grow grapes in England's cold climate.
Checking the boilers working in a block of flats
Usually when putting a new unit for use in all apartments are mounted so the boilers operating on gas or electricity. The task plumbers will not only be mounted boilers in all apartments, but also a thorough check of their safety and to adapt their work to the accepted standards. The equal time derogation will also be checking the efficiency of the installed boilers and gas leaks associated with their work. Residents should report to the administration failures resulting in their boilers and replace them only on those that are admissible in blocks for security reasons. Building administrator may also instruct mandatory exchange of the boilers, which ceased to function well.
