District heating substation components, 24 months 

 

Piping parts and connectors, 24 months 

 

Heat exchangers, 60 months 

The warranty applies to district heating substations and plate heat exchangers in use in Finland. The warranty is not voided by changes in

replacement products. 

3) Warranty content

not the case, the goods contain a defect covered by the warranty. 

However, Gebwell Oy is not liable for the defect if it can be demonstrated that the deterioration in the quality of goods or abnormal 
usability is likely due to: 

 

negligent or improper installation (e.g. insufficient support for piping, improper operating environment) 

 

exceeding the permitted maximum pressure (pressure shocks) 

 

external strain (temperature, mechanical strain, etc.) 

 

repairs by a maintenance company other than one approved by Gebwell Oy 

 

poor quality of circulating water, i.e. if the water does not meet the reference value recommendations given in report KK3/1988 
by Finnish Energy or requirements issued in Resolutions 953/1994 and 74/1994 of the Ministry of Social Affairs and Health (on 
water hardness, aggressiveness, etc.) 
 

Gebwell Oy is not liable for any indirect caused by possible damages

4) Notification of defect 
The customer must notify Gebwell Oy of the defect within 14 days of the time that it has detected or should have detected the defect. 

5) Correcting the defect 
Insofar as the defect falls within the scope of these warranty terms, Gebwell Oy is responsible for correcting the defect or providing a 
replacement product free of defects within a reasonable period of time after receiving the notification of defect. 

6) Rights of the customer after expiry of the warranty. The warranty does not affect the customer’s rights under Chapter 5 of the 
Consumer Protection Act in the event of a defect. 

7) Settlement of disputes 

The customer has the right to refer disputes arising from these warranty terms to the Consumer Disputes Board. If the dispute over 
warranty is brought before the court, it shall be heard in the competent district court of the customer’s domicile.
