Independent installation of pipes for domestic heating is quite a complicated matter, but quite doable. The basis of the work is the welding of individual sections of the pipe into the whole heating system, the connection of radiators and the heating boiler. To weld metal pipes, you will have to use the services of a welder. This procedure promises unnecessary costs, as well as smoke and soot from welding in the apartment. Well, if you decide to do the installation of heating pipes with your own hands, use polypropylene pipes for work.
The performance of the pipeline depends on the correct distribution of the pipeline your heating system. There are various schemes of heating systems, but there are two, the most popular:
The system of the upper water spill is very beneficial for its independence from the forced circulation of water. The water heated in the boiler will rise through the pipe to the upper point and through the pipeline go down through the radiators to the lower (reverse) pipe. From the return pipe the water flows back into the boiler for heating. For the operation of this system, the pipeline is mounted on a level. It is necessary that from the exit of the boiler towards its entrance, throughout the pipeline there was a slight bias for the arbitrary circulation of water.

Such a system is advantageous in that it does not require the installation of a pump for circulating water . You save on electricity, and when it is turned off, the heating system continues to work. The disadvantage of the system lies only in its lack of aesthetics. The upper tube is used with a larger diameter than in the system with the lower spill. Such a pipeline is harder to hide in the wall. In addition, saving on electricity and the purchase of a pump, you will overpay for the increased consumption of energy used for the boiler.
The bottom water spill system allows the use of plastic pipes of small diameter. Circulation of water in the pipeline will provide a pump. This type of system has a higher efficiency than that discussed above.

The advantages of installing the pipeline include laying a thin plastic pipe under the floor of the building and connection to her floor heating system. To the radiator from under the floor will come two small lengths of pipe for connection. The disadvantage of this system is its dependence on the pump. The electricity was disconnected or the pump broke - you cannot use the heating system.
Begin all work by planning the heating system. If you decide to install a heating system made of polypropylene pipes, practice soldering joints on unnecessary pieces of pipe. It will save you from unnecessary marriage at work. Based on the plan, get the required number of polypropylene pipes, fittings, taps, soldering iron.

Piping is done
After that, your heating system is ready for operation, you can turn on pump and ignite the boiler. And polypropylene pipes will give you a guarantee of high-quality system operation for at least 50 years.
