CCRES SAW PROJECT





CCRES *SAW PROJECT

 *SUN AND WOOD

Most of the CCRES projects on small-scale renewables aim to trigger market transformation by improving conditions for suppliers and installers, and by providing easy access to good quality information for end users.
Before they can be expected to buy a renewable energy system, final users must be trusted to install them property.




 





CCRES SAW PROJECT
Combination of sun and wood for producing warm water and heating for houses.  



In Croatia a combination of solar panels and firewood is proving to be a promising, reliable way of heating smaller buildings and private houses. Building owners can supply themselves with warm water and heating without resorting to imports and irrespective of the price of crude oil.



The CCRES SAW PROJECT aimed to bring together partners with a background in crafts from Croatia, EU and rest of the world to promote the necessary technologies. The goal of the project was the creation of training schemes, marketing, networks and public relations operations capable of being adapted to all final users in the future.

  3. Installing a solar hot water system is one of the best ways you can save money on energy bills and reduce your impact on the environment.



    Heating water accounts for 30% of an average Croatian household's energy use. However, a solar water heater can reduce your emissions by as much as four tonnes of CO2 per year-the equivalent of taking one large car off the road-simply by using the sun's energy to heat water at zero cost.



    The initial purchase price will probably be higher than a similarly sized non-solar water heater but the savings in energy bills will generally pay for this difference in less than 4 to 6 years. A solar hot water system generally has a longer lifespan than a conventional unit, so financial returns can be considerable over the life of the system.



    The costs for solar hot water systems range from 20.000kn to 60.000kn , with a system for an average household around 35.000kn.



    Flat panel and evacuated tube collectors



    Solar hot water systems use solar collectors (in the form of panels or tubes) to absorb energy from the sun. Water is heated by the sun as it passes through the collectors. It then flows into an insulated storage tank for later use. Some systems pass anti-freeze through the panels instead. This transfers heat to the water tank via a heat exchanger.

    There are two types of solar collectors: Flat panel and evacuated tube. Flat panel collectors consist of a dark coloured metallic absorbing plate to which a network of pipes is bonded. This arrangement is then placed in a sealed metal box with a glass cover on the top and insulation on the back and sides to reduce heat loss. As the sun shines on the collector panel the water in the pipes becomes hot due to conduction from the collector plate.



    Evacuated tube collectors consist of two glass tubes (one inside the other) that are bonded to each other at each end to form a sealed space between them (although there are single tube types too). The surface of the inner tube is coated with a heat-absorbing coating. The space between the two tubes has most of the gas removed from it (hence they are evacuated), which provides a high level of insulation, just like a thermos flask.

    Evacuated tube collectors are suited to colder climates as they can perform well even on cloudy days. In cold colder climates they are a better and more efficient option than flat panel solar hot water.

    Collector panels work best when placed on a north-facing roof. Also, ensure the collectors are not shaded by trees or nearby buildings, particularly in winter, when the sun is low in the sky.



    Storage tanks

    Hot water flows into these tanks either by a passive or active system. In passive systems, the tank is placed above the solar collectors so that cold water sinks into the collectors, where it is warmed by the sun and rises into the tank. A continuous flow of water through the collectors is created without the need for pumps.



    In active systems, solar collectors are installed on the roof and the storage tank is located on the ground or another convenient location. Water is pumped through the solar collectors using a small electric pump, which is controlled by a temperature sensing controller. This option is good if you want to limit the visual impact of the system on the roof or if your roof can not support the weight of the tank.



    The storage tank is usually fitted with an electric, gas or solid fuel booster that heats the water when there is not enough sunlight. At certain times of the year, such as in winter, the booster will run more than at other times. While the booster will consume energy during the cooler months the overall energy savings of a solar hot water system throughout the year will substantially offset your hot water costs. To help save energy locate your solar hot water system as close to wet areas as possible to reduce heat losses in the pipes. Also insulate the piping to helpfurther reduce heat losses.

  4. Wood can be an excellent fuel because it is a renewable energy source, if sustainably harvested. However, air pollution from wood fires and the transport of firewood to urban areas are environmentally detrimental.



    About 30% of Croatian homes use wood for heating, but the wood is often obtained from unsustainable sources.



    If you have a wood heater, use only sustainably-harvested wood to avoid habitat destruction and rare species extinction, and do not use treated timbers that may give off toxic pollutants when burned.



    Burn wood only in high efficiency, low emission heaters. Open fireplaces lose up to 90% of the heat straight up the chimney, making them the least efficient of all heating technologies.




    Using wood for heating - what to do


    Use clean, dry wood from sustainable sources
    Keep the air damper open to allow the wood to burn efficiently with minimal pollutants
    Fill the firebox to a reasonable height to allow good airflow around the wood, making sure that there is at least a 25mm airgap between each log
    Keep the flue and the inside of the wood heater clear of ash
    Regularly check seals around the heater doors and ash removal trays.
    Close off flues and chimneys when they are not being used-this helps to prevent unwanted drafts.



    What not to do

    Don't use damp or scrap wood that you happen to find lying around, without knowing its origins
    Never use treated pine or wood that may have been painted with toxic substances
    Don't overfill the firebox or else your wood won't burn efficiently
    Don't load up the firebox and turn the air damper down to let the fire smoulder all night
    Don't let the creosote build up in your flue-you risk having a flue fire.


    Pellet heaters



    Pellet heaters work in a very different way to a conventional wood heater. Instead of loading up a firebox with large chunks of wood and controlling the airflow, a pellet heater is controlled by giving the fuel all the air it can use and adjusting the rate that the fuel is fed into the firebox.



    Pellet heaters don't use wood in its natural form, but rather, small pellets made from wood or agricultural waste, such as rice husks.



    The waste is granulised, dried so it contains almost no moisture, and compressed into tiny pellets of a consistent size and density. They have a large surface area compared to their volume, and so burn quickly.

  5. Practically half of the EU’s renewable energy currently comes from wood and wood waste, according to the EU statistics office Eurostat, but a lack of sustainability criteria for measuring its environmental impact is stoking fears of a hidden carbon debt mountain.


    The EU's Renewable Energy Directive set a binding goal to source 20% of the bloc's energy from renewable sources by 2020. This included a target to provide 10% of transport energy from renewable sources, including biofuels.

    The directive included voluntary and contested sustainability criteria for biofuels for transport as well as bioliquids in electricity, heating and cooling.

    Biomass, either solid or gaseous, is biological material that usually derives from forested wood, agricultural crops and residues, or from biodegradable waste such as municipal waste and sewage sludge.

    In order to produce energy, it can be converted directly into heat or electricity or into biofuels or biogas.

  6. Solar thermal systems are based on a simple principle known for centuries: the sun heats up water contained in a dark vessel. Solar thermal technologies are efficient and highly reliable, providing solar energy for a wide range of applications like domestic hot water and space heating in residential and commercial buildings, support to district heating, solar assisted cooling, industrial process heat, desalination and swimming pools.
    Solar Domestic Hot Water and Space Heating


    Even the simplest solar thermal systems can provide a large part of the domestic hot water needs. With some more initial investment, 100% of the hot water demand and a substantial share of the space heating needs can be covered with solar energy. Natural flow systems work without any need for pumps or control stations. They are widely used in Southern Europe. Forced circulation systems are more complex and can cover also space heating. They are more and more common in Central and Northern Europe.
    Solar Cooling


    A growing number of demonstration projects shows the huge potential for solar assisted cooling. Solar chillers use thermal energy to produce cold and/or dehumidification. When backed up by biomass boilers, 100% renewable cooling systems are possible. Solar cooling is at the edge of wide market introduction and substantial cost reductions can be expected in the next few years. The switch of peak electricity demand from winter to summer, caused by the exploding demand for cooling, is jeopardizing the stability of power supply. Peak cooling demand is associated to high solar radiation. Solar cooling will be a key answer to this challenge in the coming years.

  7. Process Heat and Other Applications


    Solar thermal can also provide the heat needed in many industrial processes, like food production and drying, desalination of drinking water, industrial laundries etc. While ordinary solar collectors typically provide temperatures of 60-100°C, concentrating collectors can reach temperatures of 300°C and beyond. In the lower temperature range unglazed solar collectors are an effective way to reduce energy demand for swimming pool heating.


    Key Advantages:

    Solar Thermal

    is immediately available and inexhaustible– all over Europe and worldwide

    is proven and highly reliable

    allows system owners to save substantially on their heating bills

    creates local jobs and stimulates the local economy

    reduces the dependency on imported fuels

    improves the diversity of energy supply

    saves scarce natural resources

    saves CO2 emissions at very low costs

  8. A Growing Market


    During the past twenty years, solar thermal markets have shown an extremely positive evolution. Often however, periods of strong growth are followed by sharp downturns, a trend which was also visible in the past two years, where an outstanding growth of 60% in 2008 was followed by a contraction of 10% in 2009.

    With more than 4 million square meters of solar collectors sold in Europe in 2009 for the second year in a row, the solar thermal sector however still outperformed a market environment distinguished by struggling building industries in many European countries and the global economic crisis.

    Although there is an obvious correlation between solar thermal markets, fuel prices and economic activity, the market stability in our sector remains highly affected by the diversified and inconsistent landscape that support policies for solar thermal technologies show across Europe. However, this is likely to be offset by the effect on national policies of the RES directive (2009/28/EC) implementation and also because renewable heat incentives are already firmly on the agenda in several European countries.

    Reaching the critical mass for economies of scale


    Today solar thermal is one of the most cost effective sources of renewable energy. People in the leading solar thermal countries benefit from higher solar value for money because reaching a critical mass of the market allows for high quality at better prices.
    The potentials for further economies of scale in the areas of marketing, distribution, design and installation of the systems are substantial. In the collector manufacturing process, automation for large volumes is still in its beginnings.
