Guarantees and Complaints

Products available at eGrzałki.pl and all bespoke heating elements come with a standard 12-month warranty unless stated otherwise in the product description or offer. The guarantee covers material or production flaws only. The owner of the GrzałkiElektryczne.pl shop is not responsible for incorrect selection or misuse of the products.

Offered heaters are made in accordance with Polish Energy Standards (PNE).

Folding a Claim

In case of damage to a heating element during the warranty period, please review the most common causes of unaccepted complaints. If your situation does not match any of these cases, please contact us via email or telephone. You will then receive a complaint protocol, which must be submitted along with the defective product. Shipping costs are paid by the customer unless the producer specifies otherwise in the warranty card.

Causes of Damage Not Covered by Warranty

Lack of heat dissipation from the surface of the heating element
Resistance wire in the heating element burns out due to excessive temperature. Common causes:
- Lack of airflow (for heavily surface-loaded elements)
- Turning off the ventilator too quickly after the heaters are turned off
- Too high working temperature relative to the heater material
- Dense arrangement or contact between heating elements
- For water heaters: turning on without full immersion, insufficient flow for heavily surface-loaded elements, boiler scale, or sediment buildup on the heating element’s surface.
Using the heater contrary to its intended purpose
- Using a copper heater in a stainless container (electro-corrosion)
- Immersing a heater designed for air into water (non-hermetic connections, clamping bushings)
- Using oven heaters in storage heaters (excessively high temperatures)
Incorrect heater selection during device design
Heating elements are often subassemblies within a device. Proper operation depends on factors such as:
- Selection of surface material for operating conditions
- Heating environment, operating temperature, and installation method
- Spacing between heating elements
- Current and thermal protection
- Influence of environments other than water on surface/connection materials (e.g., aggressive environments)
- Insulation within the device and airflow or fluid flow conditions.
Incorrect surface load selection for the heater relative to the environment
Please check the maximum load chart for heating elements in specific environments. (link)
Connecting the heater to a higher voltage
Technically possible, but always check the power achieved after voltage increase and ensure the surface load is within limits.
Improper bending of the heater
Applies to heaters with softened surfaces. Only heaters bent by us are covered by the warranty. Customer-bent heaters void the warranty. After bending, verify electrical parameters (insulation resistance, spiral resistance, and high voltage testing at 1.25 kV). Before bending, please review the correct bending conditions. (link)

Note: Heaters are electrical devices that must be inspected and installed by an authorized electrician before use.
