hard to imagine a comfortable stay in the house without a permanent water supply.However, many owners of their own homes and cottages in the winter faced with freezing water pipes.Frost is not spared either galvanized steel pipe high-quality, no plastic products from the best manufacturers, the same hard-breaking all the pipes.To avoid such a sad outcome can be, if you timely perform the insulation of water pipes himself.

necessity of water pipe insulation
So you see the need for a water pipe insulation in your home.Given that the area is not kilometers of pipes, do not need industrial scale operations.Remember that the depth proleganiya pipe should reach half a met
Particular attention should be paid to the procedure of insulation of water pipes in unheated rooms and outside, as these places are the most vulnerable to freezing.If the inside of the aqueduct built to perform insulation and not so hard, the insulation of pipes, which are located in the street, especially in the places where they come into contact with pumps, meters, as well as in distribution wells, takes more time and effort.
materials for thermal insulation of water pipes
long past the time when the water pipe insulation produced using Sweatshirts, quilts and other materials at hand.Today, the sale is a lot of heat-insulating materials.That is why it is so important to choose the right insulation and know what to look at first.Buy material for thermal insulation of pipes is recommended on the basis of its key features and ease of installation.
choosing insulation, remember that it must meet the following requirements:
- have a low level of thermal conductivity and have good heat-saving properties;
- be durable and resistant to chemical and biological influences of environmental factors;
- have a minimum water absorption (high water repellency) as wetting the material greatly increases the performance of its thermal conductivity;
- operate at a high temperature without losing its own structure and physical properties.
Knowing the basic properties of the insulation and especially the location of water pipes on land, you can make the best choice for insulation heat insulation water pipes.Mostly they are recommended to be laid water pipe insulation indoors.
Let's look at some heaters are designed for a water pipe insulation:
- Glass wool.Fiberglass insulation is used primarily for insulation plastic pipes.From popular brands allocate fiberglass insulation Ursa, Knauf and Isover.Glass wool is characterized by low density, when using this material for pipe insulation stack it is further recommended that such external insulators as roofing felt or fiberglass.And this is a promise you additional time and costs.
- Basalt insulation.Heaters of this type operate in the form of cylinders that are easy to mount.The fiber for added protection covered with a layer of roofing material, or glassine paper, foil.Despite the obvious advantages, the cost of such insulation is not very democratic.
- Styrofoam.This insulation is the most popular material for self-warming plumbing.Polystyrene insulating shell are available with an outer coating or without.This insulating material is intended for use for reusable insulation of water pipes in the street and indoors.
- Insulation paint.This pasty gray or white, which is an innovative product in the domestic construction market.It made a lacquer composition based on water or adding an acrylic dispersion and fillers.Apply heat insulating paint is best through the spray.The thicker layer of paint you make, the pipe insulation will be higher.The paint is able to withstand high and low temperatures, and has anti-corrosion properties.By the way, one layer of paint able to replace polystyrene or glass wool.
Ways of warming water pipe underground
We have reviewed the materials that are used for thermal insulation of pipes outside and inside the premises.Some of the heat insulator can be used underground.However, such insulation method is not always easy and has many disadvantages.And so it is worth paying attention to alternative methods of insulation of water pipes in the ground, when there is no need to lay the pipe at a considerable depth.
Let us consider briefly the methods and learn how to insulate water pipes with their help:
- heating cable.Warming occurs by heating the pipe with a cable, the power of which is an average of 10-20 watts per linear meter, inside and outside of the pipe.Since winter is time lasts only a few months, the process of warming needed only at the time: the heating cable will be included only in those months.When using the insulation of pipes can not be laid at a depth of 2 meters, it is enough just to go deep by 50 centimeters.
- Warming air pipes.In this case, you can use the materials which have been listed above - polystyrene and basaltic materials.The method consists in the insulation of pipes with air, which comes from below, and the creation of so-called "umbrella" of the cold air that comes from the top.The tube was placed in a cylindrical insulation material.The result is something like a "pipe in pipe".
- Warming water pipes using high pressure.As part of this methodology in the water system crashed receiver, where and pressurized.This method will work best on submersible pumps because they are required for the system pressure (close to 5 atmospheres).But in order for the whole system was under pressure immediately after the pump immediately install a check valve.
Warming running water with your hands
All heaters, which are used today for heating water pipe, the operating principle is exactly the same.Selecting a specific insulation will depend on the location of your water supply and water-repellent properties of the material.
use of thermal insulation materials
With glass enveloping tube, and then fix the winding plastic tape.Next is to equip a waterproofing - with roofing material or other similar materials.However, insulate pipes that are located underground, fiberglass materials are not recommended.Firstly, with this method of insulation you have to equip two layers, insulation and casing itself, which consists of a coil of the heat insulator some waterproofing material.And this is quite a long and dreary, which leads to higher prices for water pipe insulation.
Since the density of such thermal insulation materials is small, the thickness of the insulation in the backfilling of the trench will be violated in height, that is, the material is simply compressed by the weight of the soil, and this process can last even one season.In the end, will miss the thickness of insulation to create a high-quality thermal insulation of underground water pipe.
If you spend filling pipes stratified compaction, it will only accelerate the process.With the lack of depth of emplacement of running water, after a long autumn rains through loose soil (after the backfill) surface waters likely reach the heat insulation and dry it for winter pore unlikely to prosper.
Insulation shell made of basalt fibers or Styrofoam, installed quickly and easily.On the water pipe with an offset of 100 - 200 mm relative to each other halves are put on polystyrene foam of a certain diameter, after being fixed with adhesive tape.The offset relative to each other is required for "an overlap", which reaches 10 - 20 centimeters.For warming corners, knots and twists made use of molded shell.
advantages of this method of insulation of water pipes polystyrene is that the water absorption for 24 hours, is only 0.5 - 2.0% by volume, so the insulation does not get wet by moisture and does not break as glass.When backfilling polystyrene will not wrinkle and get wet when penetrate through the soil surface water.The same procedure can apply insulation and water pipe passing through unheated spaces.
Application of heating cables
Consider organizing heating running water using a special cable.Just want to mention that it is not cheap, but if you mount the pipe yourself, you can save considerably.There are two types of heating water pipeline cable.Wire in the first case is held within the tube, but the installation procedure is quite complicated, and does not deal with this specialist will be very difficult.
In the second case, the wire passes over the pipe, but the power is calculated and its length before mounting the heat-insulating material.Mount it with their own hands a lot easier.By the way, are commercially available presets everything for the aqueduct, consisting of a tube with built-in heating cable and insulating material or without wires, but with cable channel, made for him.
If you use this method of heating pipes, then you do not need water to bury 2 - 2.5 meters, 50 centimeters is enough.This will require such materials: sanitary and foil tape, waterproof insulation, self-regulating cable for insulation of water pipes that has a capacity of at least 20 watts per meter.In addition, the heating cable can not only pipes do not freeze, and defrost them quickly.
process of warming water pipe heating cable takes place in the following sequence:
- through a pipe that extends from the well to the house, you need a spiral glue foil tape.Its glues are not too tight to the wire held in the performance of the winding tube.
- Thereafter the heating cable must be laid on the prepared pre-helix with a pitch of 10 - 15 centimeters.
- top of the cable should also stick the foil tape that provides wire retention.
- Insulation should be cut lengthwise and wrap around the pipe.However, it is necessary to carefully monitor the coincidence of all the joints between the conductor and the insulation, which will help prevent the emergence of "cold bridges".
- Next we must take plumbing tape and wrap very tightly over the entire pipe insulation material.Remember that the winding tape is obligatory sanitary as to prevent infiltration of ground water through gaps present.
- Once you get to the point where they exit from the water pipe under the ground and the entrance to the house, there is a need for using additional windings that can be done in several ways: through an additional insulation of cold water pipes with the help of polyethylene film and the arrangement of the frame around the pipe conduit,which will be engraved insulation.The upper part of the box and covered with a protective coating, for example, wind and waterproof film sewn up after installation.
now increasingly made to establish with the heating cable in terms of collecting data on temperature.Enough to put the 3-4 on the road sensor so you can monitor either manually or automatically.For example, if the temperature drops below 5 degrees above zero, the system will include voice messaging and send a message by e-mail or mobile phone.You can also provide automatic switching of the heating system when the preset parameters.
Secrets of proper insulation aqueduct
sure recommended to compile a detailed diagram of underground water communications in the home and on the land, and pay close attention to the connecting elements.Remember that only one small drop of water that froze in the thread is able to break them.A pipe in turn, should not be subjected to corrosion process, the best option - metal and plastic.
insulated and heated recommended all sections of the pipeline that are at low temperatures.This applies to space in the building, for example, unheated basements, and places the input pipe of the building.One method of insulation of water pipes in the country in place of the input is as follows: short sections running water to 0.5 meters that are left unheated, place in large diameter pipes.
For this use pipes made of PVC with a diameter of 100 - 150 mm, sawn along its advance.Then you need to center and fix all using tape.Drill a few holes in height, fill the space between the pipes of the spray foam construction.As you fill the holes you can cover the same tape.
Remember, warm water pipes in winter become targets of increased attention from various rodents - moles, rats and other animals.They are able to easily gnaw through insulation, asbestos and plastic pipes, considering them the most suitable warm borough.Protection from water pipes can plaster them with a solution to the broken glass, metal mesh wrapping them or by a metal sleeve.
This procedure is completed pipe insulation.The pipe with the right instruction is executed last a long time and at the highest level, without fear of severe frosts.I would like to reiterate that the warming of running water should be carried out promptly, without waiting to happen rupture due to freezing water.Always consider the water repellency, durability and conformity of thermal insulation material fire safety requirements.
