How to prepare well for the winter

BTo use the well in the winter it must be warm, but just cover the top of the box heater is not enough - it is important to know a number of nuances, which I'll discuss in this article.

In this material, we will consider the insulation of the well water in central Russia (with winter temperature of -25 degrees). If you need a separate article about the insulation wells in the north, write in a comment ↓ .

Go!

Nuance first.
The required thickness for a heater well in the central zone - 300 mm (30 cm). Of course, standard values ​​slightly below (250 mm), but it is better to put more insulation in the event of abnormally low temperatures.

Nuance second.
Between the layers of insulation would be good to make the air gap of 5-6 centimeters. For this purpose, can be laid over the lower layer of insulation bars 5 * 5 and already put them on the second insulation layer.

Nuance third.
If warming wells you use synthetic insulation (expanded polystyrene, styrofoam), keep in mind that they are only effective if stacked "one round", not halves.

My advice.
I would still use wells for thermal insulation of natural materials - mineral or rock wool. She is supple and it is possible to plug the gap. The main thing - wrap the wool from a possible film getting wet.

Do you warm up you well for the winter?
