Almost all the owners of cottages and suburban areas today provided water supply. As one of the solutions to this problem is a well, the exploitation of which does not cause problems in the summer. However, as the temperature decreases, you may encounter a problem expressed in the freezing of the supply and casing pipes.
In order to avoid interruptions in the supply of water, you need 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 so effective, therefore the above materials are rarely used separately. Quite often they act as an additional method of warming. The disadvantage is also the need to protect them from moisture.
The most effective way will be mineral wool heaters used in construction for thermal insulation. The problem can be solved once and for all, for this you can use a caisson, which is a sealed plastic or metal well that closes for the winter with a lid. In addition, it is insulated with polystyrene foam.
Interesting ways to solve the problem
Before you warm the well for the winter with your own hands, you need to think about what thermal insulation materials to choose. In addressing this issue, the climatic conditions of the terrain must be taken into account. An important role is played also by the depth of occurrence of groundwater in the place where the well is located. 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 can be used by the type of peat.
To do this, around the trunk, you should execute a box, dropping the selected material there. Thermal insulation is important to protect against water ingress, otherwise the insulation properties will be reduced. In those regions where the climate is more severe, and the groundwater level is quite high, a heater of industrial production should be used, which is selected taking into account the cost per square meter and technical characteristics.
You can choose from basalt cotton wool, polystyrene, foam, glass wool or foam rubber. These types of insulation are applied at the time of preparing the well for winter operation. Especially relevant given the choice in the case when the design is supplemented by an electric pump.
Simple rules for solving complex problems
Before you warm 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. Use this rule can be, 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 support of this fact, we can recall that in modern insulation, the air property mentioned above is often used. For example, foamed materials have small air bubbles in the composition, which are capable of increasing the thermal insulation qualities. When choosing a heater should be guided by the recommendation that the thickness of the thermal insulation should be between 30 and 35 cm.
Methods of work
If you are faced with the question of how to insulate the well for the winter with your own hands, then you need to become more familiar with the technology of work. To start, the riser needs to be sewn with a fine-mesh metal mesh, retreating from the walls 5 cm. The design is next put on the metal casing, 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 kind of backfill, which can be sawdust, they are placed in a formed space, not ramming. In order to prevent moisture from entering the thermal insulation, a steel tray should be placed under the valve, which will be removed from the metal casing. In this case, 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, the methods need to be considered. As one of them is an additional scheme of thermal insulation, which involves the use of a small heater and a floating freezing sensor. If ice forms on the surface of water, the sensor will work, turning the heater on will help to melt the ice. If you equip a well with this technology, you can eliminate the possibility of freezing, reducing energy costs.
Thermal insulation "pipe in the pipe"
Quite often dacha owners and suburban real estate owners are wondering how to insulate a well for the winter. An overview of the best ways is presented in the article. Having familiarized with them, you will be able to decide the choice. In order to reduce labor costs, the arrangement of the route from home to the well can be accompanied by horizontal drilling and puncturing the soil.
For this, the water pipe is located in a case, the function of which will be a pipe of a more impressive diameter. The pipe with the cable and the supply cable must be laid in a heated pipe, which is made of foam or mineral wool. If damaged, the damaged pipe can be removed from the case and replaced. In order for the extraction process to be 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 happen, for example, at abnormally low temperatures, you should take an emergency option, which involves resuscitation of the system with boiling water. Melt the ice cap can, using a metal 10-mm tube.
It is put on a rubber hose, which connects to the funnel. The pipe should be placed in the well until it rests against the plug. Then you need to start pouring boiling water into the funnel. Hot water will help to melt ice, and the tube will move down. After a certain time, the well will be cleaned.
It also happens that the design is OK, but the water still does not come from the frozen pipes. In this case, the problem is the elements that come from the pump. The solution to this issue can be a replacement node. If the walls of the water pipe are not covered by cracks under the influence of frozen water, it is possible to insert a 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 a well for the winter, the instructions presented in the article will help you with this. In a region where the climate is mild enough, you can refuse to install a caisson. The well head, together with the equipment, is located in a heat-insulated box that opens when necessary.
Such a structure can be built of bricks or wood. Walls from the inside are covered with insulating material. This design also performs a decorative function, which is true if the project is to bring original ideas.
Using a plastic caisson
If before you, too, was the question of how to insulate the well for the winter under water, then you can use the technology "plastic caisson". Some experts consider this approach to be the most acceptable. By locating the well head and piping below the freezing line of the soil, you ensure that you no longer have to worry about the need for thermal insulation.
At such a depth there will not be a glaciation of water, because the temperature will be above zero. To solve the problem, it will be necessary to excavate the foundation pit around the well, deepening by 2.5 m. A caisson is installed in this place. To increase the reliability of the walls and cover are insulated with foam or mineral wool insulation.
Before we warm the well for the winter with our own hands, the choice of methods must be carried out. If you are interested in the 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. Installation of this element should be done in advance, because it is undesirable to open the hatch at low temperatures.
Before you warm the well for the winter, all about insulation must be known. Having become acquainted with the rules, you will understand that it is necessary to carry out thermal insulation even before the frost hits. In addition, the inlet part of the water supply system, which is located on the street, is thermally insulated. Warming is also subject to the water supply pipeline section, which is located in unheated parts of the residential building. This should include a basement and socle.
