The "thermal solar" technology comprises all techniques that permit the utilization of the solar radiance short-waves in the form of heat.

Nowadays it is possible to find on the market a lot of equipments using this technology: solar cooker, solar drier, solar oven, solar water heater, solar equipment for industrial processes. But among all these facilities the most widespread remains the solar water heater.

Respecting the environment, the utilization of the solar water heater permits not only to protect the forests, because excluding the use of firewood as source of energy, but contributes also to the reduction of the production of CO 2.
