摘要：Considerating that the energy resources can be found in limited quantities and are not renewable, the most efficient and technically sustainable for heating the soil in early spring or late autumn in a greenhouse for vegetables is to use the solar energy. A heated greenhouse for vegetables is useful because the vegetation process can start more early or can continue later for can obtain several crops throughout the year. The paper presents theoretical researches accomplished for development an system of ecological heating in a greenhouse covered with a tough polyethylene wrap with triple layer. The heating system contains solar panels with heat-pipe vacuum tubes and an installation for heating the interior of the solarium using hot water hot air heaters, which adds more heat.
