The needs of a household space heating make up 85.9% of the total annual consumed energy. In schools operate in winter the heating system to warm the halls even on sunny days, while many industrial buildings have high demands on space heating. Coverage of the annual energy requirements is done with the consumption of expensive fuel such as heating oil and electricity. The effort to save energy in these areas is an important priority and is urgently seeking new ways and applications, so that the thermal energy consumption can be reduced greatly.
The widespread use of solar heating systems in buildings, is the appropriate solution since these systems rely on the use of an abundant and renewable source of energy, the sun.
The design of solar heating systems in the beginning construction or redesign of existing buildings should be targeted to human needs of the user of the space, but also on climatic limitations of the region in which it is installed, which is not something easy. This diversity makes impossible the existence of formalized plans to perfectly fit everyone's personal tastes and different climatic conditions
The idea of the architect can design a solar system and adapt it to the requirements of the composition using simple materials, the challenge, the solar system is working and whether it works to perform well, is the subject of this research. The construction of a solar collector from simple materials, such as common insect protection strainer, glass and insulation in this research raises the question whether such simple construction that can be the plans even spot the project engineer can spend in architectural design and how good is the benefit - cost of a system that performs decently, having cost a little money. With outgoing temperature of 63°C at 500W/m2 solar radiation when the incoming temperature is 13°C, the system performance reaching up to 71%, with construction costs less than 200 euros, the answer is that something seems to be done.
