Frequently Asked Questions

• How can I check that “Cover Sleeve 125 mm” fits exactly my appliance? The most reliable way is to compare the exact type/catalogue designation from your appliance’s (boiler, storage tank, water heater) rating plate with the compatibility stated directly in this product’s name 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 the compatibility for you.
• Why is it important to use the original/compatible part rather than a universal replacement? Parts such as gaskets, sensors or safety components (safety valves, thermal fuses) are usually dimensioned 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, an actual safety risk.
• Does this part have to be installed by a professional? For simpler, mechanical parts (e.g. gaskets, covers, small accessories with no connection to electricity, gas or the pressurised part) a handy DIY person can usually manage the replacement after disconnecting the appliance from power and supply lines. However, for any intervention in the gas, electrical or pressurised part of the appliance (e.g. sensors directly in the combustion chamber, safety valves, electrical modules) we always recommend a service technician - especially if the 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 are visible wear/cracking (in the case of gaskets and rubber parts), water or flue gas leaks at the part, an error message on the control display (for sensors and electronic modules), or a visibly reduced performance of the appliance (e.g. irregular burning in burner parts). If in doubt, the safest option 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 commonly subject to wear (gaskets, 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 older appliances, for which it can be harder to source the part quickly.
