We all wish our boilers could last forever, but the time for replacement will come eventually. If your system is beginning to show signs that it is struggling, you might need to start considering an upgrade.
Signs that you need to replace your boiler include:
It is 15 years old or older
Your energy bills are much too high
It takes much longer to heat up than it should
The pilot light flame is yellow instead of blue
It is leaking
It has been repaired several times in the last few years
