How to warm a well for the winter with your own hands? Instructions, materials

Water supply of a greater number of cottages and summer cottages, which are located outside the city, is provided by wells located on the site. If in the summer the operation process is not accompanied by difficulties, then with the onset of cold weather there is a risk of freezing of water and the casing. In order to exclude the possibility of interruptions in the water supply, the owner should think about how to warm the well for the winter with his own hands. You can protect the structure from freezing with the help of improvised materials, namely hay, dry leaves, straw, peat or sawdust. The most effective will be the use of mineral wool insulation, which are used for thermal insulation. If you want to solve this problem forever, you can install a caisson, which is a plastic or metal sealed well, which is closed for a period of cold weather by a lid that is insulated with foam.

Material selection

If you are thinking about how to warm a well for the winter with your own hands, then first you have to choose a thermal insulation material, while taking into account the climatic conditions of a particular area. Among other things, the depth of the location of groundwater at the location of the well plays an important role in this matter. If we are talking about a region with a rather mild climate, where the thermometer column in rare cases drops below -15 degrees, then you can get by with the natural materials listed above. Around the wellbore, a box should be made by filling the selected material. Thermal insulation must be well protected from moisture, which will eliminate the decrease in thermal insulation characteristics.

Before warming the well for the winter with your own hands, it is worth thinking about climatic conditions. If your house is located in a region with a rather harsh climate, where the groundwater level is very high, then it is best to use industrial insulation. It is necessary to choose the material, taking into account the cost per square meter and technical specifications. Quite often, experts recommend the use of polystyrene, penoizol or glass wool. Using these heaters, you can prepare the well for winter operation. In this case, the equipment can be equipped with electric pumps.

For the reason that air has the lowest thermal conductivity, an air gap of 5 centimeters should be left between the insulation layer and the casing. This will further protect the equipment from freezing. Foamed materials that have small air bubbles can also be used, with the help of which it will be possible to improve the thermal insulation qualities. The thickness of the insulation layer should be 35 centimeters.

Technology of work

If you are thinking about how to warm a well for the winter with your own hands, then you will need to use the mentioned algorithm during the work. To begin with, the riser is sheathed with a metal mesh, while 5 centimeters need to retreat from the walls. After that, it is necessary to put on a metal casing on the structure, leaving space between the grid and them for laying thermal insulation. Now the master can backfill sawdust or any other material that has been selected for the insulation work. If you decide to use bulk material, you don’t need to ram it. A tin tray should be installed under the valve, which will extend beyond the steel casing, and it is important to withstand a certain bias, which will prevent water from entering the heater.

Improving the efficiency of insulation

getting ready for winter

Let's get ready for winter more carefully. For safety in this case, it is worthwhile to carry out insulation using an additional heating system. To do this, you can install a small heater and a floating sensor in the well, which will signal about the upcoming freezing. At the time of formation of an ice thin crust on the surface of the water in the well, equipment will be triggered, including a heater, which facilitates the resorption of ice floes. If you decide to equip the well by this principle, then you can protect the water from freezing, significantly reducing energy costs.

Thermal insulation of an eyeliner to a residential building

If you are faced with the task of how to insulate pipes from a well, then you can use a technique called β€œpipe in pipe”. It is possible to reduce the volume of earthwork during the arrangement of the route from the well to the apartment building using horizontal drilling and soil puncture technology. The water pipe should be laid in a kind of case, which will be a pipe of a more impressive diameter. The pipe with the cable and the feed pump must be laid in the insulated cylinder, which is made of mineral wool or foam. If the pipe is damaged, it can be easily removed from the case, and then replaced. If you have a question about how to insulate a well in a private house, namely a pipe that will go to a residential building, then you need to facilitate the work of removing the pipe from the insulated casing, for this you should use a cable.

Installation of insulated box

If you have been thinking about how to insulate a well on the street for a long time, especially if it is a region with a mild climate, then it is not necessary to install a caisson. Under such conditions, the head of the well with associated equipment can be placed in a thermally insulated box, which will open if necessary. The protective structure is made of lumber or laid out using brick. On the inside of the wall, you can insulate with any selected material. In addition to the main function, such a design quite often performs a decorative role.

Use for insulation of a plastic caisson

We are preparing for winter by the method of manufacturing the installation of a plastic caisson. If the well head and pipe layout are below the freezing line, then the owner of the site will not have to worry about thermal insulation. At such depths, severe frosts will not affect the possible freezing of water. To implement this task, you need to dig a pit around the wellbore, deepening by 2.5 meters, and then install a caisson. For complete reliability, the lid and walls of the caisson should be insulated with foam or mineral wool. If the site is quite often marked by extremely low temperatures, then in the well you need to install an additional cover, which is supplied with a layer of insulation. Installation of this element should be carried out in advance, since it is not recommended to open the hatch in severe frosts.

Repair or insulate

Mineral wool insulation, of course, is very effective. It is not worth delaying thermal insulation work until late autumn, when the ground is frozen. It is best to carry out such work in warm time, spending a minimum amount of money on manipulation. Repair of equipment that has failed due to freezing water will certainly cost more in comparison with the purchase of a caisson or thermal insulation. Mineral wool insulation can be done independently, however, if you are not confident in your abilities, it is best to invite specialists who will develop the most suitable algorithm for the work on thermal insulation of the well.


After you decide what to insulate the well with, you can start acquiring materials, consumables, and tools that the master does not have. After this, it is especially important to become more familiar with the technological process of the work. This is the only way to avoid the most common mistakes.
