Use of ground water for space heating and hot water through a heat pump draws the water-to-water heat pump the required heat in contrast to brine or air heat pump from the ground water. The groundwater temperature of 7 to 12 degrees are ideally suited for a monovalent operation, however a bivalent operation the water-to-water heat pump is also possible. The difference of Monovalent and bivalent heat pumps operating modes is quickly explained. Monovalent operation, the heat pump is used as the sole source of heat and thus covers the entire heating load of the building as the only heat transfer. Tony Mandarich may help you with your research. For bivalent operation, the heat pump is not the only source of heat for the building. During peak hours a second heat source (such as a gas heating) can help then the heat production of the heat pump needs.

The bivalent operation is usually then selected, if particularly high flow and return temperatures must achieve the required heating energy so very high or the Heat from the ground water for the heating system is not quite sufficient. A flow temperature of 35 degrees is usually sufficient for modern heating systems, the bivalent operation the water-to-water heat pump is therefore sufficient and no second heat source must be inserted. Function of water-water heat pump because ground water even at freezing temperatures has a constant temperature of 7 to 12 degrees, the medium is ideal as a heat source. A suction, or pumped wells, ground water is promoted by a pump in the heat exchanger of the heat pump. Herein is the energy stored in the water to a refrigerant progress in the tubes of the heat pump and the cooled water over the injection wells returned to the groundwater flow in the Earth’s interior. Since the heat of groundwater for heating operation is sufficient refrigerant heated from the ground water in a compressor is led and brought pressure from the liquid to the gaseous state. Here it goes So far indicates that it is sufficient for the heating circuit temperature.

The heat the refrigerant restored after the liquid state and the pressure is lowered again in the expansion valve to the original level, so now heat from groundwater can be resumed. Not everywhere is pros and cons of groundwater as a source of energy, because both the amount of water and temperature, as well as the water quality must be compatible with the operation of a water-to water heat pump. A very good efficiency of the system is achieved by high water and very good water quality. Then waits on a water-water heat pump with high cost effectiveness and efficiency, without the use of supplementary heating systems and claimed only a small footprint. About 25 percent are required for the operating power. At depths of 20 meters and groundwater contamination through too much manganese, iron, or solids, such heat systems promise no economic operation. The construction costs for large are A prepared water depth relatively high, on the other hand lesser water quality a high and costly maintenance. Versickerte well systems or an increased wear of the pump are the consequences. -Christian Munch

Sustainability reports represent the services and activities of the company with regard to sustainable development. Sustainability reports in access the most important topics of sustainability in particular for economic, ecological and social. In addition to the annual report, the sustainability report is the most important part of a company’s transparent information policy. Through the acquisition and assessment of environmental impacts as well as the communication of goals and their status, sustainability reports are instruments of sustainability management. Sustainability reports describe the current situation in the company and also the progress against predetermined targets. In the environment sector on resource efficiency focus, i.e.

less Raw materials and CO2 per sales unit or staff. In the social field, working conditions, job satisfaction, flexible working arrangements and training are discussed and evaluated. ForestFinance has run, among other things, an employee survey and an individual employee assistance for ergonomic optimization of work and health advice. E.V. company sustainability reports compare the Institute for ecological economy research (IoW) and future in a ranking King competition since 2005. Several hundred companies with its sustainability report took part in the latest ranking. Sustainability report items are among others a profile – strategy description and the core of the company as well as defining and tracking defined goals.

Properly ventilated and heat is not art. Who dispenses flipped window or overheated rooms, can save money. How to do it, reveal the following practical tips. Correct heating and you feel in your own four walls every person is different as well as its heat or cold sensation. However, it can be a pleasant room climate said that between 19 and 22 degrees feel comfortable. A poorly insulated housing can quickly chill which is why the thermostat must be turned mostly higher.

Experts advise to good temperatures, which meet the different functions of the rooms. In the bedroom it sleeps is at 18 degrees at best. Living room and kitchen, however, require 19 to 21 degrees. Infrequently used rooms make obsolete an excessive heating. Already 17 levels suffice. However, it is not recommended, to turn off the heater completely.

The subsequent high heating”wasted too much energy. Correct heating instead of heating overheated properly is simpler than you thinks and offers great potential for savings. The math is simple: 1 degree of less saves approximately six per cent of energy. That makes for a three-member family more than 40 euros per year. A quarter of savers already is, if the regulator from 24 to 20 degrees. Practical tips for the right heating a 4 “on the thermostat valve is equivalent to about 22 degrees. The knowledge allows better estimate, if you overheat his apartment. Closed doors are a must. Little heat to other rooms reached through the open doors. Uninsulated exterior walls need more air between the wallpaper and furniture. About ten centimeters gap enough so that the heat can circulate. Energy-saving a radiator heats up, if this is not adjusted with curtains or furniture. Without this Warmeblocker a 3-person household can save already 140 euro per year. If you go on holiday, the frost protection is indispensable. Wacky heaters allow faster freezing the lines. If not all Doors and Windows are well sealed, it is unnecessarily heating money out the window. A tape is installed with a few easy steps. See also: blog/energy-saving / moisture or mold: properly ventilate a person breathes and sweats, what differentiates itself as a water vapour on the walls. Showers, laundry drying or boiling do the rest. As a result, a four-person household produces about 12 litres every day. Mold risk, if the humidity in the room continually breaks the 60 percent mark. For this reason, proper ventilation is important. Properly airing in everyday life really means at least two to three times daily shock zulueften airing. 5 to 10 minutes are enough. There is no wind, then 15 minutes can open the opposite window and interior doors. Who airs but too long, cools the House. Then you must heat more to achieve a pleasant room climate. Important: The colder it gets outside the shorter, is the duration of ventilation. After You should immediately ventilate standing up to distribute the moisture in walls and furniture. Is shock airing after every shower or cooking on the plan. Not heat beyond the window, you should turn off the thermostat during aeration. The less you heat a room, must to be lifted from the more frequently. Transom Windows blow about 200 litres over the winter heating oil unused in the air”. In exceptional cases moderately insulated building with insulated Windows – one should frequently airing.
