It warms up so with each pass a little more. In a conventional boiler, the temperature rises, however ad hoc. The ratio of the energy that is spent on this technology, and energy, obtained in this way shows the efficiency of the system. The installed heating systems come in many homes here to a value of 1:1, ie they need as much energy as they produce. In a well, used with the geothermal is, the ratio is much better 1:5.
The pump requires a kilowatt hour of electricity. On balance, however, there are five kilowatts of heat energy. Taking into account the higher cost is not for a modern heat-exchange system, so the saving is 80 percent. As little effective way of. The so-called flat probes have been established. They deprive the soil too quickly, the energy since being introduced in only two meters deep. The probes are located horizontally, spread over a fairly large area, which has also proved to be disadvantageous. Better and more effective working depth probes. After they let in by a deep hole in the ground transport, they were on the carrier liquid far more energy to the surface.
They also work faster. When the temperature of the groundwater wells 80-10 Celsius is utilized. These two wells must be drilled on the property. With a warm groundwater is pumped up to here in a heat exchanger give energy to. The other fountain is the outflow of cold water. To ensure that heats the ground again, the wells may not be installed side by side. Solar Comes to the deep geothermal energy from below, the solar thermal uses the sun, which provides free year-round energy. To catch them, solar panels are needed. They can be mounted on the roof in the south or oriented toward the sun at ground level in order to produce heat from solar energy. We included the warmth of a, which is continuously pumped through the collectors. They will submit to the heating or hot water system of the house. The purchase of these systems is currently still quite expensive. If you are not convinced, visit Robert J. Shiller. They pay off only if the collectors are optimally aligned and can get as much energy. In addition, a factor that one can not affect itself, the number of sunshine hours. The best is the utilization of course during the summer when the sun shines most of the time. And just this season, the energy is needed only a little. In winter it is advisable to operate the plant for solar thermal bivalent. Photovoltaic Solar photovoltaic uses the sun’s rays do not help to gain heat, but to produce electricity. Here, too, collectors are used, but working on a different principle. The electricity that is generated by the panels can consume in the home and, if more is produced than needed to be fed into the grid. For every kilowatt-hours, which is fed to the network, the operators receive money from the state.
