How To Apply Thermal Paste To Cpu 2010

BHE complete without welds

Rising energy prices and dwindling resources, lead builders, planners and architects to a targeted change in thinking. An environmentally friendly and economical alternative renewable energies present here the dar.
The boreholes RAUGEO PE-Xa probe before the transfer.

REHAU has recognized this trend and has been working long and increasingly used for the exploration and increased use of energy from solar, geothermal and biogas one. Besides the fact that these energies are renewable, environmentally friendly and climate-friendly, they also ensure the safe and adequate supply of future generations. In addition, existing cost reduced active and achieved independence from the ever-rising energy prices werden.Um set a positive example, and renewable energy also at its own site to make good use of REHAU is currently equipping in order to obtain his heating and cooling system. Here are 11 boreholes in the future of a reversible ground source heat pump, a heating and cooling in the amount provide 60 kW. This is a halving of primary energy use by 372 900 kWh / a to 203 700 kWh / a can be obtained. This represents a saving of 46% and a reduction in CO2 emissions of 50 t / a. This pioneering project is also part of the green building program that was launched by the European Commission into being. Goal of green building is, building owners and encourage operators to identify economic savings in non-residential buildings and nutzen.Geothermie - Clean Energy from the ErdeDie environmentally friendly form of energy using geothermal energy in Germany from a depth of 1.2 meters can be used effectively. There is already at 18 meters depth a continuous temperature of 10 ° C, which rises 100 meters by a further 3 ° C. The heat from the ground heat pumps are usually used to work in principle as refrigerators. The refrigerator cut the material to be cooled heat that is released via cooling fins on the environment. The heat pump is similar: they cut off the bottom of special pipe systems - such as probes or collectors - heat and releases it at a higher temperature level in the air again. Bury and forget: BHE RAUGEO probe PE XaDie geothermal probes cross-linked polyethylene REHAU are manufactured according to strict guidelines and meet the highest Standards of quality and resilience. The probe RAUGEO PE-Xa is being perceived as the geothermal probe on the market with absolutely no welded joints in the ground. This makes them very reliable, because no leaks in welds or other connections can occur on the probe. RAUGEO probe can be used up to temperatures of 95 ° C and thus usable for heat storage purposes.

clear view to save energy at home

For new residential buildings must have been years of an energy certificate will be issued - from 1 January 2008 to such a statement after the government will be mandatory for all buildings.

For homes with up to four apartments that were built before 1978, the so-called demand certificate is required. As with washing machines, refrigerators and dryers have long been common practice to give the passport buyers and tenants information about the energy efficiency of a building. Also it should include recommendations for modernization. This is how the energy performance certificate help to motivate owners to save energy and thus contribute to climate protection. We answer the important questions about the energy performance certificate:
Who must have an energy certificate?
who rent from 2008 for an apartment or a house for sale or will have to present the prospective customer an energy certificate.
Are there any building for the same card?
No, the type of card depends on the size and year of manufacture of a building. For houses that were built in 1978 or later, for commercial buildings and office building just a consumption certificate requirement: it only indicates the energy consumption of the previous inhabitants. For houses with up to four homes that were built before 1978, however, the so-called demand certificate is necessary to evaluate the technical characteristics as well as thermal insulation and heating of a house and is much more meaningful. However, it is more complex and expensive. Consumer and tenant pads, however, hope that this demand certificate is due to the demand from buyers and tenants prevail as the only building pass energy.
is Who in the Energy Performance Certificate?
the card may be issued architects, engineers, chimney sweeps or energy consultant. For the demand certificate as they investigate the thermal insulation of external walls and roof or the boiler and hot water. For the consumption certificate, however, it is sufficient to call the experts basic information, such as year of construction, energy and the electricity and heat consumption of the last three years.
How much costs an energy certificate?
For a simple house with no basement and extensive roof, it will cost to industry sources, around one hundred euros if a professional prepared the document. The larger a home and depending on how often was modified or grown, is expected to increase the bill of the skilled person to 300 to 900 euros.
how long the card is valid?
Once a passport is issued or energy for ten years to be valid.
