20-Year Warranty. Because we can afford it.



Especially when it comes to heat and electricity, security of supply is crucial. With solar solutions from GASOKOL, you rely on the most constant energy source of all: the sun.

We have perfected our way of working over almost half a century, having thus become one of the most reliable partners in the field of solar energy throughout Austria and in Europe.
For that reason, we can afford to give you a 20-year warranty.

Defects resulting from manufacturing faults or from using inferior materials in the products we manufacture will be repaired by us free of charge.
The trust and satisfaction of our customers are enormously important to us – that is why our warranty promise goes beyond the legally stipulated minimum.

The warranty period starts as of the date of production (year + calendar week on type plate). Any warranty claim may exclusively be submitted to the contractual partner of GASOKOL GmbH. The warranty period and the scope of application are fixed in the customer’s master data sheet, as amended. These warranty provisions are only valid according to our GTC and in connection with a written agreement with GASOKOL GmbH.
