How to insulate well for the winter at the lowest cost - Proven Ways

owners of private buildings, as a rule, prefer self-contained water supply.Their advantages are obvious, and it says a lot.In most articles dealing with source selection, emphasis on the feasibility of well everything on the site.One of the main arguments - the water in it does not freeze, so it is much better than well.

But this is not taken into account some of the features of traditional, proven by centuries of hydraulic structures.Firstly, there is little indicating that not all wells need insulation, and, secondly, that if necessary, such activities can be performed independently, without significant material cost and effort.Let us examine what wells require insulation and methods by which it is done.

Wooden frame

These wells are not subject to the full insulation.Wood belongs to a class of materials that have very low thermal conductivity.Therefore, the penetration of "cold" inside only possible on.Therefore, this part of the well and need to insulate.There are various methods that can be selected on the basis of the characteristics of the region's climate (maximum "freezing" temperature).

Warming cover

The best option, if it is also made of wood.A further decorate it is possible differently: obbit felt, Styrofoam glued to the bottom plate (cut to size), completely cover the top of the log with any material.A good host will always find the most appropriate way.As an option - from plastic laying mineral wool layer.On sale there are special cover of the w / w, equipped with plastic hatches for access to water.

Construction «house»

This homemade "birdhouse" not only further protects the upper part of the well from frost, but also make it more convenient sampling water from it in the event of a failure, such as a pump.

Well of the Rings w / w

Such designs require high-quality insulation, because the concrete - a good conductor of heat.Thus it is necessary to take into account the depth of soil freezing.. As a rule, it is 1.5 m insulated below this mark makes no sense, since the temperature of the water and soil - are the same.

No need to explain that to insulate the external part of the well must be "bare" to a sufficient height.

Materials

insulation options are many.Here are the most convenient in terms of performance and not very expensive.Those who are willing to spend a considerable amount, it makes sense to ask, for example, a "sandwich" technology.The following methods - from the category of "low cost".

Styrofoam

On sale there are special half-rings (called "shell") of different diameters.The compound is very common - on the principle of "thorn-groove".We just need to place the joint halves to seal further.But it is necessary to provide for the possibility of dismantling and insulation (for example, when cleaning, handling more rings spetssostavami), so used, for example, mounting foam is not desirable - it halves stick together "shell."

Keramzit

well arranged around a kind of formwork.Such an enclosing frame can be build of wood (waterproof thick plywood board impregnated with antiseptic), MDF.Inside filling made of expanded clay, the material must be of different factions.In this case the layer will be as dense.The peculiarity is that the well will have to dig around a "square", although it is difficult.

Polyurethane

This method is more qualitative, but will have to invite specialists, as the spray mixture is made with a special installation.The cost is quite pay off, as this insulation will serve at least 30 years.Furthermore, coating is continuous and thick, which considerably increases the quality and waterproofing.The only condition - the work is carried out at a temperature below 20 0C.

For information

On sale are ready to cover the wells.They can be ordered, and to the required size.Estimated cost - 5 800 rubles.If warm water well completely, for their services invited masters will take not less than 16 000 rubles.

Practical recommendations

While digging a well is likely damage to the waterproofing layer.Before warming, you need to carefully examine the entire surface, and fix potential defects.

Some site owners believe that once carried water intake pump, it can be an insulation worry.Argument - the device is located closer to the source of the bottom, and deep well not be chilled even in the most severe frosts.But the question arises - if the pump or some other element of the "scheme" fails?Repair of "5 minutes", especially in the winter, do not get to make.How to be?

In addition, the ice "plug" can cause a shift of the Rings, and fix it pretty hard, but in the winter - it is impossible.That is why the well of w / b of products subject to mandatory warming.

For northern regions need to determine the depth of frost penetration is not less than 2 m.
