What is solar ventilation?
It is important to distinguish between solar fans, which operate on solar power, and solar air collectors, which use the sun’s energy to heat air and channel it into a building for heating and ventilation. We offer solar air collectors from Grammer® Solar, which we deliver throughout Switzerland.
What is the cost of solar ventilation?
We offer Grammer® Solar solar ventilation systems starting at CHF 1,500–2,000 per square meter of solar surface area throughout Switzerland. The exact price depends on the number and size of the solar air collectors, the accessibility of the installation site, and the travel time to the site. Ask us without obligation for an individual offer.
What are the advantages and disadvantages of solar ventilation?
Solar air collectors provide automatic ventilation of the building, entirely without incurring electricity costs. The solar heated air creates a comfortable indoor climate and leads to lower heating costs during the cool seasons. The system is considered to be very reliable in operation with low maintenance requirements.
Who is Haustrocknung.ch?
Since 2010, Haustrocknung.ch has specialized in dehumidifying buildings, which we dry out sustainably using innovative systems. We recommend the eco-friendly ventilation system from Grammer®Solar because it significantly improves the indoor climate through air circulation.
How much does a solar ventilation system cost in Switzerland?
Grammer®Solar’s solar ventilation system is available starting at CHF 1,500–2,000 per square meter of solar surface area. This price includes the entire order processing. The actual price depends on the size and number of air collectors, the accessibility of the installation site, and the distance we have to travel to reach the site.
What are the electricity costs associated with a solar ventilation system?
The solar ventilation system from Grammer® Solar operates completely independently because it generates the electricity for the fans itself. If the system is equipped with the night ventilation option, annual electricity costs of CHF 25 may be incurred during night ventilation.
How does solar ventilation affect heating costs?
Solar ventilation channels free solar heat into the house, resulting in lower heating costs.
What maintenance costs and expenses should I expect?
Apart from changing the filter, which should be done once or twice a year, the system requires absolutely no maintenance costs or effort.
How does solar ventilation work?
The solar and air collector from Grammer® Solar generates electricity, which powers a fan. This fan draws in air, which first passes through a filter, is then heated in the air collector, and finally circulates throughout the entire house. The free solar heat creates a healthy and comfortable indoor climate, prevents mold, and keeps the house dry. As soon as the desired room temperature is reached, the system shuts off automatically.
What can solar ventilation do?
The standard version of the Grammer® Solar ventilation system automatically brings warm air into the house. This creates a comfortable indoor climate, lowers heating costs, and reliably protects against moisture and mold in the home. In addition, the ventilation system can be optionally retrofitted with a night ventilation kit, which connects the ventilation system to the home’s electrical grid. This allows the house to be cooled with cool night air on a timer and, if necessary, ventilated on a user-controlled basis.
Does solar ventilation filter pollutants from the air?
Yes, the aspirated air first passes through a filter before entering the house. This filter should be replaced once or twice a year. Apart from that, the system does not cause any maintenance expenses.
What is the maximum ventilation capacity of the air collectors?
Grammer® Solar's air collectors supply up to 125 m³ of air to the building per hour. Incidentally, the system ventilates the building even when the sky is cloudy.
For which buildings is solar ventilation suitable?
Grammer®Solar is suitable for single-family homes, vacation homes, mobile homes, garden sheds, greenhouses, and specific areas such as basements or attics. Thanks to its temperature-regulating effect, the ventilation system is particularly practical for homes that are unoccupied for several weeks. In addition to residential homes, the system can also be used in commercial or agricultural buildings.
Where are the solar air collectors installed?
The air collectors are mounted on flat roofs, pitched roofs or on facades - either flat or at an angle. The ideal location should receive as much sunlight as possible and have no partial shading.
How noisy is solar ventilation?
The operation of solar ventilation is virtually silent.
How do I control the solar ventilation?
The ventilation system is controlled automatically by a thermostat. As soon as the desired temperature is reached, the system shuts off. When the nighttime ventilation option is enabled, the system operates on a timer.
What is the procedure for installing solar ventilation?
After the initial consultation, we will prepare a quote tailored to your property. If you accept it, the air collectors will be installed on the roof, on the facade, or in another suitable location as agreed. Where necessary, holes will be drilled for the ventilation pipes. In some cases, a lift may be required for the installation.
How long does it take to install solar ventilation?
The installation of solar ventilation usually takes one day. The duration of installation depends on the accessibility of the place where the collectors will be installed, as well as the number and size of solar air collectors.
What is the lifetime of solar ventilation?
Grammer®Solar estimates the service life of its solar air collectors to be at least 25 years. The collectors are certified in accordance with the collector standards DIN EN ISO 9806 and DIN EN 12975-1 and have been manufactured in Germany for over 40 years.
Questions & Answers
How the solar air collector works
- As soon as the collector receives enough sunlight, the fan automatically turns on.
- Fresh outside air is drawn in through a filter and passed through the insulated air collector, heating the air by up to 40°K.
- Subsequently, the warm air enters the building through an insulated pipe.
- The humid, stale air goes outside through exhaust vents. [1.]
