Almost all owners of cottages and suburban areas today provided water. One of the solutions to this problem is the well, the operation of which in summertime does not cause problems. However, with a decrease in temperature, you may encounter a problem expressed in the freezing of the flow and casing.
In order to avoid interruptions in the water supply, it is necessary to think in advance about how to insulate the well for the winter with your own hands. You can use for this:
Each of these methods can be considered not as effective, so the above materials are rarely used separately. Quite often, they are an additional method of insulation. The disadvantage is the need to protect them from moisture.
The most effective way to become mineral wool insulation used in construction for insulation. The problem can be solved once and for all, for this you can use the caisson, which is a sealed plastic or metal well, closed with a lid for the winter. Additionally, it is warmed foam.
Interesting solutions to the problem
Before insulating the well for the winter with your own hands, you need to think about which insulation materials to choose. In addressing this issue should take into account the climatic conditions of the area. At the same time, the depth of groundwater in the place where the well is located also plays an important role. If it is drilled in a region with a mild climate, where the temperature outside the window rarely drops below -15 ° C, then natural materials like high peat can be used.
To do this, around the trunk should perform the box, having filled there the selected material. Thermal insulation is important to protect well from the ingress of water, because otherwise the insulating properties will be reduced. In those regions where the climate is more severe, and the level of groundwater is quite high, you should use a heater of industrial production, which is selected taking into account the cost per square meter and technical characteristics.
You can opt for basalt wool, polystyrene, foam, glass wool or penoizol. These types of thermal insulation are applied at the time of well preparation for winter operation. This choice is particularly relevant in the case when the design is supplemented with an electric pump.
Simple rules for solving complex problems.
Before you insulate the well for the winter with your own hands, you should remember some laws of physics. In this case, we are talking about the main ability of air, expressed in poor thermal conductivity. You can use this rule by leaving some space between the protective layer and the casing. The thickness of this gap can be 5 cm. This layer will protect the well from freezing.
In confirmation of this fact, we can recall that in modern insulation quite often the above mentioned property of air is used. For example, foam materials have small air bubbles in their composition, which are able to increase the insulating properties. When choosing insulation should be guided by the recommendation that the thickness of the insulation should be from 30 to 35 cm.
Method of work
If you are faced with the question of how to insulate a well for the winter with your own hands, then you need to take a closer look at the technology of work. To begin with the riser, it is necessary to sheathe a fine-meshed metal mesh, retreating from the walls of 5 cm. A metal casing is put on the structure in the next step, while it is important to leave space between it and the mesh for thermal insulation.
At the next stage, it is important to determine the type of backfill that sawdust can take as it is, they are placed in the formed space without tamping. In order to prevent moisture from entering the heat insulation, it is worthwhile to install a steel tray under the valve, which will be removed outside the metal casing. It is necessary to ensure a slight bias.
If you are thinking about the question of how to insulate a well for the winter with your own hands, methods should be considered. One of them is an additional insulation scheme, which involves the use of a small heater and a floating freezing sensor. If ice forms on the surface of the water, the sensor will work, turning on the heater will contribute to the melting of ice. If you equip a well with this technology, then you can eliminate the possibility of freezing by reducing energy costs.
Thermal insulation "pipe in pipe"
Quite often, gardeners and owners of suburban real estate ask how to insulate a well for the winter. An overview of the best ways is presented in the article. After reviewing them, you can make the right choice. In order to reduce labor costs, the arrangement of the route from the house to the well can be accompanied by horizontal drilling and soil puncture.
For this, the water pipe is located in a case, the function of which will be performed by a pipe of a more impressive diameter. A pipe with a cable and a power cable must be laid in a heat-insulated pipe, which is made of foam or mineral wool. If necessary, the damaged pipe can be removed from the case and replaced. To make the extraction process simpler, remove the cable from the protective cover.
When warming the well with your own hands did not allow to achieve a positive result, which can occur, for example, at abnormally low temperatures, you should use the emergency option, which involves reanimation of the system with boiling water. Melt the ice plug using a metal 10 mm tube.
It is put on a rubber hose that connects to the funnel. The pipe should be placed in the well until it hits the plug. Then you need to start boiling water in the funnel. Hot water will help to melt the ice, and the tube will move down. After a certain time, the well will clear.
It also happens that everything is in order with the construction, but the water still does not come from the frozen pipes. In this case, the problem lies in the elements that come from the pump. The solution to this issue may be the replacement node. If the walls of the water supply system are not covered with cracks under the influence of frozen water, you can enter the heating wire into the pipe using a special device. It is important to choose a cable that can be used in water supply systems.
Installation of heat-insulating box
If you are thinking about how to insulate the well for the winter, the instruction presented in the article will help you with this. In the region where the climate is mild enough, you can refuse to install the caisson. The wellhead with the equipment is located in a heat-insulated box that opens when necessary.
Such a structure can be built of brick or wood. The walls inside are covered with insulating material. Such a design also performs a decorative function, which is true if you add original ideas to the project.
Using plastic caisson
If you also had a question about how to insulate a well under water for the winter, then you can use the “plastic caisson” technology. Some experts consider this approach the most acceptable. By having the well head and pipe routing below the soil freezing line, you guarantee that you will no longer worry about the need for thermal insulation.
At such a depth will not occur glaciation of water, because the temperature will be above zero. To solve the problem, it will be necessary to dig a ditch around the well, going deeper by 2.5 m. A caisson is installed in this place. To increase the reliability of the wall and the lid is insulated with foam or mineral wool insulation.
Before you insulate the well for the winter with your own hands, the choice of methods must be implemented. If you are interested in a caisson, then its installation may involve the installation of an additional cover with its thermal insulation above the well. This completely eliminates the possibility of ice formation in the pipes. The installation of this element should be carried out in advance, because opening the hatch at low temperatures is undesirable.
Before insulating the well for the winter, you need to know everything about the insulation. After reviewing the rules, you will understand that the insulation should be carried out before the frost hit. Additionally, the input part of the water supply system, which is located on the street, is insulated. Insulation is also subject to a section of the water supply pipeline, which is located in unheated parts of a residential building. This should include the basement and basement.
