An expansion tank for a boiler is a device that absorbs excess pressure caused by heated water expanding in a closed heating system.
2: Why do I need an expansion tank?
An expansion tank is essential to prevent pressure build-up, which can damage the boiler and piping, ensuring safe operation.
3: How does an expansion tank work?
The tank contains air and water. As water heats and expands, the excess volume pushes against the air, balancing the pressure in the system.
4: Where should I install the expansion tank?
The expansion tank should be installed on the supply line of the boiler, ideally near the boiler itself for optimal performance.
5: How often should I check my expansion tank?
Regularly inspect the expansion tank for signs of wear or leaks, ideally during annual boiler maintenance.
6: Can I replace an expansion tank myself?
If you have plumbing experience, you can replace it yourself; otherwise, hiring a professional is recommended for safety and proper installation.
