"The basement earth heats up": I didn't believe in the myth, and made the floors of the house ever warm

Among construction and paramount misconceptions, perhaps the most powerful is the idea that a building spot (in simpler terms, the soil under the house) does not freeze just because it is heated by "the earth itself." That is, the core of the planet heats the magma, and the heat is transferred upward, right into the basement of your house, which is on a strip foundation.

A bunch of people are absolutely sure that they have + 5-6 degrees of heat in the underground, even in winter, only due to the fact that this warmth of the earth rises upward.

I will not scoff at the lost for a long time, and I will say that such a temperature is kept in the underground rather because part of the heat (very average ~ 10-12%) leaves the apartment building down through the floor. And this is despite the fact that a warm elastic medium (water, air) tends to rise upward.

I hope now you understand why in the house, especially in a wooden house, in winter you just can't walk barefoot on the floor - it's cold. E

then the basement cools your floor.

By the way, I am also a resident of a log house with wooden floors, 60 out of 100 sq. M. its area, and this problem is relevant to me. Was.

Until I installed a heat accumulator in a subfield up to 60 cm high. The heat accumulator solves two tasks: it cuts off the cold of the earth from lateral freezing (see photo below) and actually accumulates heat in summer and autumn.

What does a heat accumulator look like?

And this is a simple design: a pillow made of 80 mm of compacted sand, 100 mm of insulation (foam) and 80 mm of reinforced concrete screed. If I made a 100 mm screed, I could safely introduce underfloor heating pipes into it.

The conclusions (supply-return) of these pipes can be connected to a solar collector and dried, heated, gaining heat into the thickness of concrete during a hot summer period. Then in the winter bare feet will say "thank you".

You will be surprised, but in the summer it heats the water to a temperature of 80-90 degrees. More artisanal collectors - 60 degrees. This heat is more than enough to heat a concrete slab, close the vents and not freeze in winter.

I leave room for your questions, comments and advice.
