in most Soviet-built homes (mostly "Khrushchev")You can still find cast-iron battery (radiators).These batteries have several advantages (iron rust worse than metal), but there are new and improved types of radiators, which makes the installation of the latter more and more attractive with each passing year.The advent of better battery life makes it necessary to apartment owners to think about how to replace the radiator.
In order to change the radiators, firstly, the need to remove the old ones.you must make sure that the system has no water (if summer) pre-drained her out and shut off the risers (if the heating period) before removing the old batteries.Then dismantle the connection pipe or grinder to cut the pipe feeding coolant into the radiator.But before you cut, you need to decide in advance what is the length of the pipe will be needed to establish a new battery.Therefore, before removing a battery, you need to
How to choose a heating radiator, which will replace the old battery?An important factor plays a design (appearance) in choosing a new battery, and do not forget about the technical parameters, new radiators do with light.Easy is good for transport, installation, and also makes a convenient self-temporary removal of the battery for repairs at the site of deployment of the radiator (plaster walls and gluing wallpaper).Important technical parameters of new radiators is the possibility of venting and floor water supply without turning off the riser.The latter condition is especially important during battery leakage, when it can be repaired during the winter supply of coolant to the house, at the same time without disturbing the neighbors and causing public services employees to shut off the entire house.
After the pipe that supplies coolant to the radiator, unplug the old battery, you must remove it from the mounts, and then remove (tear) the old mount.At the same time should visually inspect the pipe feeding coolant, for their life and rust level.If such a pipe with a riser suspicious, and should provide replacement.
In some cases, the owners of apartments do not have high demands on design, or radiators installed in non-residential premises (garage, warehouse, shop), also have the opportunity to make such a radiator yourself.How to make a radiator in the home?Basically, such radiators are made of thick metal pipe (diameter 150 - 200 mm.) Plugged at their ends.Four equal lengths of such pipes (1 to 2 m.) Are welded to each other by means of smaller diameter pipe so that the coolant in the radiator to circulate snake.On the opposite side of the pipes from the place where the coolant will be supplied, welded valve (three-quarters) for draining water, so that the latter would be located at the bottom.Cranes can also be installed at the entrances to the radiator for closing the water supply.Before installation of the radiator it is filled with water to check for leaks.If a leak is sealed place.
temperature in the heated using radiators room will directly depend on the area of contact with the outside surface of the battery.When installing such panels factory area depends on the number of radiator sections.How to calculate the number of radiator sections, if it is done in-house?The inability to answer this question is the main disadvantage of installing radiators.Typically, the optimal number of battery sections factory or diameter of tubes (as well as their number and length) improvised determined by "trial and error" because the same cubage different rooms sometimes requires quite different parameters radiators.The apartment can be a corner or on the contrary, even with the wall insulation, windows and balcony.If central heating, installation of radiators is better to have a reserve, as when it is very hot - you can open the window, and when it's cold - there is only cold.
