  1. Thermal conductivity and moisture absorption coefficient should be as low as possible. Also it is worth to test its water-repellent ability.
  2. The heater must provide fire safety and in accordance with the sanatorium conditions.
  3. It is very easy to assemble and operate this heater with the possibility of reuse.
  4. Insulation for outdoor use must be resistant to dampness, chemicals, non-rotting and corrosion.

How to insulate pipes in earth by the most common materials?

  • Glass fiber insulation - inexpensive, but effective. Manufactured and sold in rolls. When installed, it is applied to the surface and simply wrapped with wire and other means. Quality brands - Knauf and Ursa.
  • If this material is used, the waterproofing process for this fiber will become necessary. And this, after all, extra money.
  • Basalt-cotton wool insulation. Its characteristic feature is high density and heat engineering. It is used for insulation of pipelines, heat and waterproofing in factories, etc. It is obligatory for the installation of a heater: follow the convergence of joints on the surface.
  • Two listed insulation are suitable for pipes of different diameters. Other materials require preparation for a specific diameter, structure and placement. Where better to choose a universal material!
  • Polyethylene insulation for premises. Will be the very first solution for the insulation of the pipeline, for example, in the basement or other non-residential premises of the house. It looks like a cut pipe, the size, matched in advance, is put on an existing pipe and this provides thermal insulation. This heater, in addition to blanks, also has heat insulation sheets, which are filled with foam polyethylene, which ensures a low level of moisture permeability.
  • Styrofoam or, as they say, polystyrene. Thanks to it, water pipes are insulated both in the ground and indoors. Installation is carried out by cutting a pipe from a foam plastic, on which the edges have a design form, that is, snap on the moment of alignment of the elements.

In addition, how to insulate pipes in the ground also depends on the type and purpose of the pipeline.

The most problematic places of pipelines are wells and caesons, which supply water to pipelines and pumps. If these pipes freeze, there will be no water in the house. The reason for this is the insufficient depth of the pipes and, of course, the lack of insulation

For the insulation of pipes in the street, waterproofing materials are required, therefore, be sure that they were of high quality. For example, it can be a roofing felt, which is also wound on a pipeline to counteract climatic conditions.

Options for solving the problem of "how to insulate pipes in the ground"

Recently, various electrical appliances, for example, heating cables and tapes, have become very actively used for thermal insulation of pipes.

  1. Installation of heating devices.
  2. Wrap the foil tape. Evenly and not very densely, that distribute heat in space from the heating element to the pipe. For metal pipes, this is not necessary.
  3. Extend the electrical cable along a line or a spiral so that the windings do not intersect and do not overheat the structure.

Depending on the cable model, they are attached in a different way. So as not to dig through the soil, it is necessary to insulate the entire system of electrical heating, that is, to lay both the layer of the heater and the layer of waterproofing.

When choosing a heating cable, pay attention to its features:

  1. Cheaper in price and optimal in quality are resistive systems, although they are characterized by high energy consumption.
  2. Expensive and versatile - self-regulating tapes, they have a small power consumption.

As mentioned earlier, a dangerous place for pipes insulation is a well, since it is most susceptible to low temperatures and difficult to insulate. Therefore, the most optimal solution for wells can be a device box in which to lay or cover the insulation( waterproofing), by the way, you can even from cheap. Saving here does not hurt, and emergency work will be avoided for several years!
