Hot Air Collectors + Solar Air Heating Systems
New Energy portal devotes itself to DIY solar air collectors. This solar heating systems work very effectively and thus can replace a significant portion of fossil fuels - they can save oil and gas.
The solar air collector uses air as a medium which is heated in the collector and blown by a fan directly into rooms that need to be heated. The solar air collectors thereby contributes directly to energy savings. It works independently and can be retrofitted to almost any building.
Due to the simple and efficient construction, air collectors are ideal for DIY home improvement.
The five types of collectors
The solar air collector types I & II and the windows are collectors that can be rebuild cheaply. The facade collector as a precursor to the S-Line collector has heated my home for 2 years.
The newly developed S-Line collector with an efficiency of 75% and a peak power of 1,500 W is one of the most powerful air collectors on the market. The S-Line collector is the logical development of my previous DIY panels, exhibits leadership and innovation in air suction. It can be simply replicated. My building instructions are for ecological reasons only available as ebook in pdf format and the S-Line collector additionally as DVD.
Printed versions of the assembly instructions are not on offer by New Energy Portal. Construction manuals, kits and parts for DIY available in the New Energy Portal Shop.

The S-Line Solar Hot Air Collector is a complete new development and based on the experience of the 4 previous Solar Hot Air Collectors that Dip. Ing. Stefan Brand has developed since 2008.
For many decades, buildings have be heated with solar air collectors and supplied with heated fresh air.
The DIY Constuction Manual describes how the Trubadu S - Line collector can be rebuild. Solar Air Heaters, however, can vary widely and be combined with existing heating systems. Depending on their purpose of usage and type of building changes may be required and/or necessary.
The goal of developing the Trubadu - hot air collector was to create a cost effective and simple way to enable people to create their own energy. All components are readily available and the production cost of the collector is between 150 € and 220 € per square meter of collector area. Thus avoiding a long payback period.
The result is a heating system in a modular design, which is characterized by a low overall height, and offers the possibility to use different types of absorbers. By optimizing the air suction, a uniform air flow is achieved below the absorber plate which thus increases the efficiency of the solar air heater.
Solar air heating panels can be retrofitted to a variety of single family homes and thereby contribute to energy savings. Payback periods range from 4-7 years.
The main components of the solar air heater are the absorber plate, the air duct and an electric fan. The absorber plate collects energy from the sun rays and converts them into heat. The air duct and fan help to transport the gained heat from the solar air heater into the house.
Hot air won from the solar air heater is then used directly for the heating of rooms by passing it through a piping system into the rooms.
Therefore, the solar air heater can be used even at low solarization and be energetically effective and efficient at the same time.
The sun produces when it shines on average about 800 W / m² - max. 1000W / m².In Germany this averages to around 1,400 hours per year. This is roughly equivalent to 1,200 kWh / m² per year - heat that can easily be utilized. According to the current state of the art this heat energy can be converted to cover around 5 to 20% of your home's heat supply. The total solar air collector area should be roughly 5.5 m² and a heating time of 700 h of solar heat gain.
The construction of the collector should be no problem for any technically skilled person. A well-stocked hobby workshop is, however, a prerequisite.
With solar air collector systems you can generate per square meter per year between 100 to 350 kWh heat (calculated for the the season in which heaters are being used from October to May). During this period the solar air heaters can be used for heating and ventilation of buildings.
The peak performance of the Trubadu collector is in full sunlight about 1500 watts.
Warm air from the solar air heater can hold more moisture. If the air is heated during the day within the solar air collector, the hot air is able to absorb moisture from the premises, before the air moves through the openings in the kitchen, bathroom, and then out again. In this way, moisture and odors are removed from the house and reduce the risk of mold growth. This is of advantage especially for building that are rarely used such as vacation houses. Also to de-moisturize cellars the warm air of the solar air heater can be applied.
