Thermal solar energy or thermosolar energy is based on the use of the solar energy to produce heat for cooking or producing hot water for the domestic use, either potable hot water, central heating or to produce mechanical energy and, thereafter, electric energy. In addition, this hot water can be used in an absorption cooling machine, which uses heat instead of electricity for cooling, for instance, premises.

Particularly, Tecnoambient employs thermal solar energy to produce hot water, by flat panels or vacuum tubes, and, with lots of successful installations, to support central heating by radiating ground, where solar energy is ideal because it works with low temperature. In this installments, TecnoAmbient installs solar collectors of vacuum tubes due to its high performance.
