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

Water supply of more cottages and cottages, which are located outside the city, is provided by wells 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 water and casing. In order to rule out the possibility of water supply disruptions, the owner should consider how to insure the well for the winter with his own hands. Protect the structure from freezing can be with the help of improvised materials, namely hay, dry leaves, straw, peat or sawdust. The most effective will be the use of mineral wool heaters, 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 that closes during the cold period with a lid, which is insulated with foam.

Material selection

If you are thinking about how to insulate the well for the winter with your own hands, then for the beginning it is necessary to choose a warming material, while taking into account the climatic conditions of a certain area. Among other things, the depth of the location of groundwaters in the location of the well plays an important role in this matter. If we are talking about a region with a fairly mild climate, where the column of the thermometer drops below -15 degrees in rare cases, we can manage the natural materials listed above. Around the wellbore, it is necessary to make a box, filling up the selected material. Thermal insulation should be well protected against moisture, which eliminates the reduction of thermal insulation characteristics.

Before you warm the well for the winter with your own hands, it is worth considering the climatic conditions. If your house is located in a region with a rather harsh climate, where the water table is very high, it is best to use an industrial heater. Choose material is necessary, given the cost per square meter and technical specifications. Quite often, experts recommend using polystyrene, penoizol or glass wool. With the help of these heaters, it is possible to prepare the well for winter operation. In this case, the equipment can be equipped with electric pumps.

For the reason that the air has the lowest values of thermal conductivity, it is necessary to leave an air gap of 5 centimeters between the insulation layer and the casing. This will additionally protect the equipment from freezing. You can apply foam materials that have small air bubbles, with the help of them it will be possible to increase the thermal insulation qualities. The thickness of the insulation layer at the same time should be 35 centimeters.

Technology of work

If you are thinking about how to insulate the well for the winter with your own hands, you will need to use this algorithm when carrying out the work. To start, the riser is covered with a metal fine-mesh net, while the walls need to retreat 5 centimeters. On the design after this, you need to put on a metal casing, leaving between the mesh and the space for laying the insulation. Now the master can backfill the sawdust or any other material that was chosen for the insulation work. If you decide to use backfill material, you do not need to ram it. Under the valve should be installed tin tray, which will extend beyond the steel casing, it is important to withstand a certain slope, which eliminates the ingress of water into the heater.

Increasing the efficiency of insulation

Let's prepare for the winter more carefully. For safety in this case it is necessary to carry out the warming by means of an additional warm-up system. For this purpose, a small heater and a floating sensor can be installed in the well, which will signal the forthcoming freezing. At the time of the formation of the ice thin crust on the water surface, the equipment will operate in the borehole, including a heater that promotes the dissolution of the ice. If you decided to equip the well on this principle, the water can be protected from freezing, by significantly reducing energy costs.

Heat insulation of the liner to the house

If you are faced with the task of how to insulate pipes from a well, you can use a technique called "pipe in a pipe". To reduce the amount of excavation work from the well to the residential building, you can use horizontal drilling and soil puncture technology. The water pipe should be laid in a kind of case, in the quality of which will be a pipe of a more impressive diameter. The pipe with the cable and the feed pump must be laid in a heated cylinder, which is made of mineral wool or polystyrene. If the pipe is damaged, it can easily be removed from the case, and then replaced. If you are faced with the question of how to insulate a well in a private house, namely a pipe that will go to residential construction, then it is necessary to facilitate the removal of the pipe from the insulated housing, 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, it is not necessary to install a caisson. Under such conditions, the well head with associated equipment can be placed in a heat-insulated box that will be opened if necessary. The protective structure is made of sawn timber or laid out using bricks. From the inside of the wall can be insulated with any selected material. In addition to the main function, this design often performs a decorative role.

Use for insulation of a plastic caisson

We are preparing for the winter by the method of manufacturing the installation of a plastic caisson. If the well's borehole and pipe routing are below the freezing line of the soil, then the owner of the site will not have to worry about the thermal insulation. At this depth, severe frost will not affect the possible freezing of water. To implement this task, you need to excavate a foundation pit around the wellbore, deepening by 2.5 meters, and after installing the caisson. For full reliability, the lid and caisson walls must be insulated with foam or mineral wool material. If the site is 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. The installation of this element must be done in advance, since it is not recommended to open the hatch in severe frosts.

Repair or insulate

Warming with mineral wool, of course, is very effective. Do not delay the work on insulation for late autumn, when the earth will be frozen. It is best to conduct such work in a warm time, spending a minimum amount of money on manipulation. Repair of equipment that failed due to freezing of water, probably will cost more than buying a caisson or carrying out thermal insulation. Warming with mineral wool can be made independently, but if you are not confident in your abilities, it is best to invite specialists who will develop the most appropriate algorithm for carrying out work on the thermal insulation of the well.

Conclusion

After you have decided what to insulate the well, you can start acquiring materials, consumables and tools that are not available from the master. After this, it is especially important to get acquainted with the technological process of the work. Only in this way you will be able to avoid the most common mistakes.
