A serious problem of Earth is the environmental pollution. "Save the Earth!" The improvement of the human life's quality, and a better meeting of higher comfort claim the renewed energies. The heat pump is an energy saving and environment protecting machine, installation creates the harmony of the building with the environment, it makes use of the Earth's heat and reduce the harmful air pollution. We can find a man friendly heating systems with their use. The usage of equipment with the renewed energy can be decentralised and its operation cost is much cheaper than the cost of the traditional equipment. The "transition" from the traditional energy sources to the using of new sources will be gradual. |
