save on heating energy using solar
To save on heating energy and money
Is it to replace a boiler in retrospect a grant? Does a geothermal heat pump at a night storage heater make sense? In the TV-telephone campaign many readers the advice of experts around looking around the energy-saving heating.
Trier. (Kat) Here is a selection of questions from readers and responses from experts on the subject of heating and how you can save money:
We can replace a boiler. Is there still a subsidy after the event?
Sabine Mikic, relationship manager at the State Trust Bank of Rhineland-Palatinate: A grant is available for the Federal Office of Export and Economic Control (BAFA), when a solar collector system is installed. Even later is a deficit is possible. A boiler exchange, which is in planning can, under certain conditions to be funded by the state with a grant. Information can be obtained from the Land Trust Bank of Rhineland-Palatinate on the phone number 06131/4991991.
I did three years ago, an old boiler, built in 1974, replaced by an oil fired condensing boiler with solar system. But I have no savings. Why might that be?
Helmut Kramer, honorary consultant at the center for energy Rheinland-Pfalz: The replacement of an old boiler with an oil condensing boiler, you can be in control of the energy savings of at least 20 percent. Some sources of error when you are: There may be unwanted circulation in the solar system. The entire casing should be checked. You can also find on the calorimeter, as produced much heat the solar system. And see if the water heater can be replaced by solar heat. Talk to the plumber that installed the system.
Can I get a piece of wood boiler funding?
Helmut Kramer: No, currently there are no mere piece of wood boilers more funding. Funding is available pellet boilers and combination boilers pellets and logs.
I live in a house that was built in 1950th Nine years ago I had an exterior wall insulation of ten centimeters can be attached. I have night storage heating and think about a ground source heat pump. Does this make sense?
Elisabeth Foit, honorary consultant at the center for energy Rheinland-Pfalz: The geothermal heat pump in combination with surface heating, a floor or wall heating can be operated. Geothermal heat pumps to achieve an average water temperature of 35 degrees and 70 degrees for heating would be required. The difference would be produced by electricity and that should be avoided at all costs!
Our house is almost 40 years old, the heating system as well. Except for the burner that was replaced in eight years. We are considering to pellets or gas switch with a LPG tank in the garden. Or should we stick with oil?
Elisabeth Foit: In view of the effort if you want to leave a LPG tank set up in the garden, you can also think about a pellet heating. Especially since you could use the place of the existing oil tanks.

sun environmentally-plus action every buyer of a climate-friendly Consolar solar energy system funded with a lucrative bonus
(Business Wire) Frankfurt am Main, 16.11.2010, time for the cold season starts Consolar the new Environmental Action Plus: Who from now until 31 March 2011 renewable energy from solar heat Consolar umsteigt benefited from the temporary promotional premium. Eligible, each purchase of a Consolar-system with all available collectors – and according to the current promotion of government per square meter collector area commenced. Includes the TUBO-collector for a house such as 9.4 square meter, saving the buyer’s 450 euros. Including the current funding of the federal government for the buildings are then obtained a total of 1350 Euro grant. Thus protecting the owners not only money, but have been actively involved in quality and climate change: For the collectors of Consolar are specifically designed for the highest standards back and won several awards, including the eco-label “Blue Angel” and the award of eco-test. For more information about Green Plus action and the terms and conditions are available on the website at www.consolar.de.
Switching to solar energy, pays itself several times – this understanding would emphasize Consolar with the Environmental Action Plus. According to the Federal Government, the heat supply by 2030, mainly made with renewable energies. Prerequisite for this is efficient solar solutions, such as the tube collector TUBO, which was awarded by Öko-Test recently as “the most efficient collector” in the test. The flat panel 27 has PLANO Consolar turn of the highest solar fraction per collector, such as eco-test confirmed in a comparison study. He is very powerful and was combined with the COAX memory as a complete system also awarded the “good” eco-test.
Consolar for example, provides also the only manufacturer to ten years warranty against glass tube breakage by thermal shock, hail or frost on the TUBO vacuum tube collectors. How reliable are the collectors, shows their use on the first CO2-free Arctic research station Princess Elizabeth in the Antarctic. The SOLUS TUBO-system of Consolar supplied the research team there, even at low temperatures with heat.

heat your hot water for the bathroom with solar-collectors
Hot water can be easily prepared with sun rays. The solar technology, the homeowner can tap into the sun is by now mature. Although solar panels for hot water as well as cheap for the profits of electricity not used photovoltaic systems, but thanks to government grants to pay off the investment.
Compared to oil or gas-fired plants come on a solar energy from 50 to 62.5 percent per year. Solar geysers that support the hot water and heating in buildings are, in addition to the seals on the roof panels from memory, control equipment and accessories such as pump or temperature sensor. 2008, the heat production of 5.3 billion kilowatt hours of solar systems. Rising.
Solar heated water: Good for the environment
Why waste oil, gas and electricity, if water can be heated with solar energy? This is a question more and more households. And the investment worth it: So a family of four saves a year in the hot water heating by solar compared to oil or gas about 180 €. They are in 25 years, 4,500 euros, or about as much as a solar system cost including installation. The state encourages this bit for the environment with a grant. Such a plant to conserve the environment.
The sun heats the water almost free. One can also use it and connect around the dishwasher to the hot water network. With special washing machines and ballasts can also use hot water for laundry. In summer, the plant switches off as early as midday, because the store is fully heated. With a few tricks can be exploited more solar energy: the morning shower, wash dishes and rinse. It can even be useful in order to heat the basement – prevents moisture and mold problems.
Ad
Excess heat can save in special “buffered” are. Sun is, at least in summer, enough at night and during bad weather ready warmth. Still can not be supplied by solar energy throughout the hot water. Especially in winter, you have to continue with additional oil and gas.
Another tip: The mostly black-painted panels for water heating on the roof are robust and therefore less susceptible to interference with professional installation. Nevertheless, appropriate insurance coverage for the assets, except for freak weather of tennis with hail, hurricanes and meter-thick snow loads causing particularly vandalism (such as stone-throwing children) and theft currently major damage.
Who uses the system only for its domestic water heating and heating support, which has under its homeowners’ insurance a basic protection, but also only for the insured risks such as storms, hail, fire, lightning, and tap water.
Recently, solar panels to generate heat only supported under certain conditions. As the Federal Ministry of Environment announced that the planning, construction and testing of pilot and demonstration plants with a minimum size of 100 square meters of collector area will be encouraged. The same goes for large solar geysers as sole preheating of drinking water.
advantages and disadvantages of solar energy
These are the advantages and disadvantages of solar energy
The more energy prices rise, the more attractive is the production of electricity on their own. Solar cells on the roof or in the garden and also promise free electricity produced from clean to the sun. But the investment will pay actually in a photovoltaic system for the conversion of light? What are the disadvantages and advantages of solar energy?
At the border of the sun rays hit Earth’s atmosphere with an energy of 1.367 kilowatts per square meter on. On the way to Earth is the biggest part of it lost. It is reflected by suspended particles such as dust or ice crystals and converted into heat. The only good ten percent of the radiation reaching the ground, may nevertheless cover all needs of the people. But who wants to use the power of light itself, should weigh the disadvantages and advantages of advance solar energy exactly. Because the energy is emission-free and free indeed, but in return requires much space and expensive technology.
Solar energy is free and clean
The sun is an inexhaustible source of ready and free source of energy. This is probably the biggest plus, considering advantages and disadvantages of solar energy. Who his own power from the solar system shall respect the price the supplier no longer fear also.
The investment in a photovoltaic system is not negligible, but is subsidized by the government. Based on the Renewable Energy Law. Nevertheless, the subsidy pays the technology for Germany. Already, according to a balance sheet of the Green Group in the Bundestag in the solar industry more than 60 000 people in more than 100 companies employed who have to do with the design, construction and installation of photovoltaic systems. The turnover of the sector in Germany is ten billion euros, of which two thirds of the remaining value in the country and bring the federal tax revenue of three billion euros each year taxes.
Ad
An important issue among the disadvantages and advantages of solar energy is definitely the climate. The information that could in this way, the emission of carbon dioxide alone in 2009 to 3.6 million tons will be reduced. Because with the energy or particulate matter and greenhouse gases.
Solar energy to the costs for all
Solar radiation is not continuous, and not to the same intensity available. It is dependent on weather, time of year and time of day. Without the technology to store that is not a constant energy supply is possible.
Until the solar systems alone supplied the same amount of energy, has been the need for their production pass, depending on the technology from 1.5 to 3.5 years. This has the Energy Research Centre of the Netherlands is calculated in a study. However, photovoltaic systems with up to 40 years, a long life.
Unique is the result when comparing the advantages and disadvantages of solar energy from the cost factor. Since the photovoltaic cuts off badly, because according to the Renewable Energies Act, the additional cost of generating solar power allocated to all German consumers. And those with 40-50 cents per kilowatt hour considerably. Electricity from wind power costs, however, with 6-8 cents per kilowatt hour or as much as the product in traditional power plants energy.
Although the share of solar power in the German energy consumption of only about one percent of all federal citizens have to dig deep for it in the bag. The calculations of the Rhine-Westphalian Institute for Economic Research found the promotion of solar energy has already cost the taxpayer € 14.3 billion. The solar magazine Photon goes from 77 billion euros.
Solar energy as renewable energy
Solar energy is renewable energy to brake as little
The development of solar energy as renewable energy is obtained primarily by advances in climate policy momentum. In Germany, renewable energies such as the solar energy in recent years have grown into a significant industry. In 2010, only 12.5 percent of electricity come from renewable energy sources.
They often have enjoyed in summer on its solar panels on the roof. For the summer brought a growing number of households for free hot water and considerable revenue from the homemade solar power. It is good business for both the operators of photovoltaic systems as well as for the environment. Each solar-generated kilowatt hour of energy saves the environment up to 300 grams of the greenhouse gas carbon dioxide.
Solar energy as renewable energy is available for anyone
Solar radiation is subject to daily and seasonal fluctuations of zero to about one kilowatt per square meter. To the stream but to use as possible around the clock may have additional measures such as energy, feedback control or auxiliary systems, such as a fuel-powered boiler, is necessary.
Solar energy is currently at the hydro and wind renewable energies behind in third place. Other renewable energy sources such as biogas, bioethanol, wood and geothermal energy.
Ad
The share of renewable energy in total final energy consumption has not changed since the beginning of this millennium, more than doubled and is currently at 10.1 percent.
The sun is the most inexhaustible source of renewable energy
With the help of solar technology can be the solar energy use in different ways: solar panels generate heat (solar thermal and photo thermal), solar thermal power plants produce with the help of heat and steam electricity plants and plant waste is processed to useable liquids (eg . ethanol, rapeseed oil) or gases (eg biogas cleaned, it will create methane). Solar cookers or solar ovens heat food or sterilize medical supplies, solar cells produce direct current electric (photovoltaic).
The use of solar energy as a renewable and renewable energy in Germany is funded by the Renewable Energies Act (EEG). Already 20 percent of homeowners have a solar energy to electricity or heat. More technical uses of solar energy are being tested.
Researchers are working on an energy mix in order to replace nuclear power can continue. The caching of surplus energy currently plays a minor role, as currently in the German electricity mix, the proportion of thermal power plants, including biomass-fired power plants more than 85 percent. That will change gradually.
It has been calculated that start in the year 2162, the lignite, hard coal in 2083, 2063 and 2038, the uranium gas needed. The crude oil that is currently most important source of energy, dry according to the calculations in the year 2031. Solar energy, however, is almost constant. The applied radiation energy is 10,000 times higher than the total energy demand in the world. But it must be noted that these are not always and everywhere available. In Germany, you can expect an average of 1600 hours of sunshine per year, to equator takes up to 3500 hours of sunshine a year.
Efficient solar heating for buildings
So far solar equipment for older buildings were not very useful. The relatively high heat demand for heating in older buildings makes a solar heating in those buildings considered economically inefficient.
The manufacturer of the system Solaera Consolar offers a particularly flexible system of solar heating, the heat of a solar equipment for the building stock and that is interesting. So far, only the connection of a pellet or a pellet stove to the Consolar Solaera system was possible. Recently, can the existing gas boiler or oil heater are integrated into the system.
Especially for less well-insulated buildings with high heat is the Consolar Solaera system as a real alternative to heating with renewable energy. While a normal solar heating covers only 20-40% of the building heat, score the Consolar Solaera system according to the manufacturer a solar coverage rate of up to 85%. May be covered with a building heating system of up to 13,000 kW / h. If we take the support of a pellet or a heating system with fossil fuels is working to up to 25000 kW / h can be achieved. Ideal for owners of family houses or small apartment buildings.
Solaera of Consolar makes itself a particularly effective combination of solar, heat pump and storage tank to use. Unlike traditional solar panels used here a hybrid collector. Seems the sun gives off its heat to the collector, the solar fluid. With an overcast sky or at night, is blown through the collector and ambient air made the heat contained therein also to the solar fluid. Another special feature of the solar storage tank. Standard solar storage tank will be mounted as a buffer layer or memory, the memory Solaera is a latent ice storage, which can provide on a much smaller space, more heat. Thus, the latent heat offers 320 liters of the same heat as a 2,500 liter storage tank water-based. The heat pump and ice storage are directly combined in one compact device, in addition to save space and no further connection pipes required.
The sun delivers enough heat, it will be delivered directly to a combined storage tank that supplies the building with thermal energy for hot water and heating. Are the progress of the solar system to low temperatures, latent heat of the power station with the low temperatures will be loaded. When heat is required to turn on the heat pump and useless in the latent heat contained a higher temperature to produce, which is then delivered to the combined storage or fed directly into the heating.
Is the performance of heat pump and solar panels to cover no more out to the heat, turns an ordinary boilers as peak load boilers. This, however, the heat pump is not switched off completely. In similar system concepts usually the heat pump is switched off completely.
The system is in heating modernization is an ideal complement to the existing boilers, which can continue to serve as a peak load boiler at extremely low temperatures. In particular, owners of low boilers can benefit here. The solar heating of Solaera Consolar is a high end system for heat generation.
Solar Heating – Solar equipment for every application
(PA) Basically, four systems for a solar thermal heating are available on the Solar Market:
1st Solar heating with combined storage – The solar heated storage tank as a tank in the drinking water solution in a separate bubble – separated by a buffer of water / heating water
2nd Solar heating with combined storage – Here is the principle similar to – but no internal tank is used, but in a solar storage integrated stainless steel corrugated pipe with a relatively low water volume. The objective here is to close the hot water flow in the amount required to provide.
3rd Solar heating with separate solar water storage – so called Duo solar systems. In addition to a storage tank is a water / drinking water solar storage used.
4th Solar heating with fresh water station – the most modern type of solar hot water extraction. The solar equipment combined with oil or gas or wood heating, etc., the heating water heated in the buffer. This heat exchanger is heated by a plate of fresh water to the desired volume and temperature.
Which solar heating system is an appropriate way to apply results from many factors. It is the increasingly popular stoves with water bag require heating, the different heat sources intelligently together.
The Gerenda Solar specializes in solar thermal systems. Under http://www.gerenda-solar.de DIY / home improvement find affordable and high quality solar heating systems from different manufacturers (Wagner Solar, ESTEC, etc.) to choose from.
solar heating systems design
* Presents the collaborative work of international experts from research, industry and academia in the IEA solar heating and cooling programme’s Task 26, Solar Combisystems
* Details methods for analysing and optimizing combisystems for different house types
* Introduces standardized classification and evaluation processes and design tools for these systems
The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice.
Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favors an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.
Contributors include key figures working on solar combisystems worldwide (Austria, Denmark, Finland, France, Germany, Norway, Sweden, Switzerland, the Netherlands, USA).
