Frequently Asked Questions

• How can I verify that „Sensor KTF20 - Silicone 2m“ fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation on your appliance's (boiler, tank, water heater) rating plate with the compatibility stated directly in this product's name (Atmos brand) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including the serial number, if available) - we will be happy to verify compatibility for you.
• Why is it important to use the original/compatible part rather than a universal replacement? Parts such as seals, sensors or safety components (safety valves, thermal fuses) are generally sized precisely to the parameters of the specific appliance (pressure, temperature, sensor electrical resistance) - an incorrect part can cause reduced functionality, leaks, or, in the case of safety components, a genuine safety risk.
• Does installing this part have to be done by a professional? For simpler, mechanical parts (e.g. seals, covers, small accessories not connected to electricity, gas or the pressurised section), a competent DIY handyman can generally manage the replacement after disconnecting the appliance from power and the system. However, for any intervention in the gas, electrical or pressurised part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electronic modules), we always recommend a service technician - especially since such intervention could affect the validity of the warranty on the whole appliance.
• How do I know this part is worn and needs replacing? Common signs include visible wear/cracking (for seals and rubber parts), water or flue gas leaking at the part's location, an error message on the control display (for sensors and electronic modules), or a clearly reduced function of the appliance (e.g. irregular burning in the case of burner parts). If in doubt, the safest approach is to have the condition assessed by a service technician during the regular annual inspection.
• Is it worth keeping this part at home as a spare? For parts that are subject to normal wear (seals, fuses, small mechanical parts) and whose failure would mean a shutdown of heating or hot water production, keeping a spare on hand is a sensible precaution - especially for an older appliance, for which the part may be harder to obtain quickly.
