Solar heating
Would you like to save up to one third of heating costs with solar air collectors? We design and install air collector solar heating.
Solar heating support for house or apartment
Conventional solar thermal collectors use solar energy to heat water, which can then be used to heat the radiators in the house, for example. Air collectors, on the other hand, heat the outside air and filter it and feed it into the house. As air absorbs the solar heat directly, without the detour via the medium of water, air collectors are very efficient.
In direct sunlight, solar air collectors can heat the outside air by up to 40°K, and by 4°K to 10°K when the sky is overcast. In other words, if it is cloudy outside and the temperature is 16°C, the collectors still deliver an air temperature of at least 20°C into the house. As soon as the air becomes too warm or too cold, the air collector switches off.
With 1 m² of collector area, 8 m² of living space can be heated. In old buildings, this can save up to one third of the heating costs. The disadvantage of solar air collectors compared to photovoltaics or solar thermal is that the energy cannot be stored and used at a later time. On the other hand, they work reliably even on cloudy days, when photovoltaics and solar thermal already provide hardly any energy.
Haustrocknung.ch is an owner-managed company based in Bern.

Questions & Answers
What is solar heating?
Solar heating generally refers to solar collectors that heat water, which is then used to heat the radiators in the house. In contrast, we offer solar air collectors that channel solar-heated air into the house.
What is the cost of solar heating?
Haustrocknung.ch offers solar heating systems with solar air collectors from Grammer® Solar from 1,500 - 2,000 EUR per square meter of solar surface. The exact price depends on the number and size of the solar air collectors, the accessibility of the installation site and the travel time. Ask for a non-binding quote.
What are the advantages and disadvantages of solar heating with air collectors?
Automated ventilation with solar air collectors ensures a pleasant indoor climate all year round, reduces the risk of mold and noticeably lowers heating costs in winter. Solar air collectors have the highest efficiency of all solar systems - unlike photovoltaic or solar thermal systems, however, they cannot store the energy and use it at a later time.
Why a solar heating system from Haustrocknung.de?
We have specialized in the topic of humidity in buildings since 2010 and are familiar with the installation of ventilation systems. We only install high-quality solar air collectors from Grammer® Solar, which have been manufactured in Germany for over 40 years and are the first air collectors in Europe to be certified with the Solar Keymark. The Keymark helps consumers to choose products that meet European standards.
How much does solar heating cost?
The installation of a solar air collector costs approx. 1,500 - 2,000 EUR per square meter of solar surface. The price depends on the characteristics of the collector, our installation effort and the travel time. We will be happy to prepare an individual offer for you.
What are the electricity costs for solar heating?
Solar ventilation from Grammer® Solar is completely self-sufficient, as it generates the electricity for the fan itself. If the system is equipped with the "night ventilation" option, electricity costs of around EUR 25 per year can be incurred.
How does solar heating affect heating costs?
According to the manufacturer, solar air collectors can save up to a third of heating costs in old buildings. The actual cost saving depends on the condition of the residential building and the amount of sunlight on site and can vary greatly in individual cases. However, the efficiency of solar air heating is often underestimated and is surprisingly good even when the sky is overcast.
What maintenance costs and expenses should I expect?
The filter should be changed once or twice a year. Otherwise, solar air collectors are practically maintenance-free and deliver a very constant output over decades.
How does solar heating with air collectors work?
The solar air collector from Grammer® Solar generates electricity and uses it to drive a fan. This draws in air, which first flows through a filter, is then heated by up to 40°K in the air collector and finally circulates throughout the house. As soon as the desired room temperature is reached, the system switches off automatically.
What can the solar air heating all?
Solar heating from Grammer® Solar brings free solar heat into the house. This ensures a healthy and comfortable indoor climate, reduces heating costs, prevents mold and keeps the house dry. Optionally, the air collector can be equipped with a night ventilation set, in which the ventilation is connected to the house's power supply. This allows the house to be cooled with cool night air on a time-controlled basis and ventilated under user control as required.
Does the solar heating filter pollutants from the air?
Yes, the sucked-in air flows through a filter before it enters the house. This filter must be changed once or twice a year. Otherwise, the system is maintenance-free.
How effective are solar air collectors on cloudy days?
While the air in the collector heats up by up to 40°K in direct sunlight, it is still 4°K to 10°K when the sky is overcast. This may sound like a low yield, but it actually corresponds to the highest efficiency of all solar systems. With an outside temperature of 16°C and an overcast sky, the air collectors still deliver an air temperature of at least 20°C into the house.
Where does solar heating make sense?
Solar heating systems with air collectors are mainly used for smaller residential properties, such as detached houses and apartment buildings, apartments, vacation homes, cellars, garages, mountain, hunting, fishing and club huts, mobile homes, tiny houses and caravans. Solar air collectors are also suitable for larger residential and industrial buildings, such as multi-storey residential buildings or as a drying system for wood chips, hay, firewood, biofuels or malt.
How big should the air collector be?
Up to 8 m² of living space can be heated per square meter of collector area. With this dimensioning, the entire room air volume is exchanged 2.5 times per hour.
What to consider when installing solar heating?
Air collectors are mounted on flat roofs, pitched roofs or on façades - either flat or inclined. The ideal location should receive as much sunlight as possible and not be partially shaded.
How is the solar heating controlled?
The ventilation system is controlled by a thermostat. As soon as the desired temperature is reached, the system switches off. With night ventilation, the system operates on a timed basis or at the push of a button.
How does the order work?
After an initial consultation and property inspection, we will draw up an offer tailored to your property. If you agree, we will install the solar heating system. A lifting platform may be required for installation.
How long does it take to install the solar heater?
The installation of the solar heating system usually takes one day. The installation time depends on the accessibility of the installation site and the number and size of the solar air collectors.
How long does a solar heater last?
Grammer® Solar expects a service life of at least 25 years. The collectors have been manufactured in Germany for over 40 years and are certified in accordance with the collector standard DIN EN ISO 9806 and DIN EN 12975-1.
