How to insulate a water pipe in a private house
Hello. We plan to equip the well and the water supply in the suburban area. Since frosts often reach -35 ° C in our region, we worry that pipes will freeze in winter. Tell me, is there an effective way to insulate water pipes?
Answer
It is possible to prevent freezing of a water pipe in a suburban area using several heat-insulating materials:
- polystyrene foam;
- basalt insulation;
- glass wool or mineral fiber.
Styrofoam insulation is good in that the manufacturer produces it in the form of a thick-walled shell of two or three components, and a similar shell exists for pipes of any diameter. Due to its good hydrophobicity, polystyrene foam does not lose its properties when wet and has a long service life.
Basalt insulation is also available in the form of a casing, only due to its flexibility it has the shape of a hollow cylinder with a longitudinal section for installation on the pipe. The advantage of such thermal insulation is its good mechanical strength and ease of installation.
Mineral fiber roll heaters have good thermal insulation and have the lowest cost, but when wet they lose more than 50% of their protective properties. In this regard, choosing glass wool as a heat insulator, be prepared for the installation of waterproofing from roofing material or fiberglass.
Finally, we note that no matter how high-quality thermal insulation is, it does not warm the pipe, but only prevents the penetration of cold to it. For this reason, it is necessary to mount the water supply as deep as possible. If this is not possible, then use heating cable.
