Frequently Asked Questions

• How do I check that the "Safety Valve AVANSA STS for Cooling Loop" fits my device exactly? The most reliable way is to compare the exact type/catalogue designation from your device's (boiler, tank, water heater) nameplate with the compatibility stated directly in this product's name (AVANSA brand) and in its technical parameters above. If in doubt, write to us with the exact type designation of your device (including any serial number if available) - we will be happy to verify compatibility for you.
• Why is it important to use an original/compatible part, and not 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 device (pressure, temperature, sensor electrical resistance) - the wrong part can cause reduced functionality, leaks, or, in the case of safety components, a real safety risk.
• Must this part be installed by a professional? For simpler, mechanical parts (e.g. seals, covers, small accessories not connected to electricity, gas, or the pressure part), a handy DIY enthusiast can usually manage the replacement after disconnecting the device from power and supply lines. However, for any intervention in the gas, electrical, or pressure part of the device (e.g. sensors directly in the combustion chamber, safety valves, electrical modules), we always recommend a service technician - especially since such an intervention could affect the validity of the warranty on the entire device.
• How do I recognise that this part is worn and needs to be replaced? Common symptoms include visible wear/cracking (for seals and rubber parts), leakage of water or flue gases at the part, an error message on the control display (for sensors and electronic modules), or clearly reduced functionality of the device (e.g. irregular combustion 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/service part? For parts that are commonly subject to wear (seals, fuses, small mechanical parts) and whose failure would mean a shutdown of heating or water heating, keeping a spare in stock is a sensible precaution - especially for an older device for which it may be more difficult to obtain the part quickly.
