Boiler - what is it?
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.

frequently performed plumbing
Plumber in carrying out their tasks running in different rooms and at different heights. He should, therefore be sure of their safety. To ensure the safety of its employees are also required hydraulic company directors. Often the work performed by plumbers are repairing leaking taps and cisterns, as well as washing machines and boilers. However, large hydraulic projects are associated with the performance of water and sewage networks in homes and apartment buildings, as well as all other public buildings. In carrying out their work with builders plumbers and even the fire brigade. Sometimes plumbers deal with lecturing tiles in bathrooms and kitchens.
Worth to know - plastic pipes
Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications.
Plastic pipe systems fulfil a wide variety of service requirements. Product standards for plastics pipe systems are prepared within the standards committee known as CEN/TC155. These requirements are precisely described in a complete set of European Product Standards for each application alongside their specific characteristics.
For example:
Conveyance of drinking water: Hygienic requirements
Conveyance of gas: Highest Safety requirements
Plastic pipes for radiant heating and floor heating: Temperature resistance over decades
Sewer applications: High chemical resistance.
Plastic pipes are perfectly capable of fulfilling the specific requirement for each application. They do so with a high level of performance over a long lifetime and with reliability and safety.
The key factor for success is achieved by maintaining consistently high quality levels. For plastic pipe products, these levels are closely defined by the different standards.
Two key aspects are fundamentally important for the excellent performance of plastic pipes: flexibility and long lifetime.1
