All gas boilers have an average lifespan of 15 to 20 years. When it comes to deciding whether you need to replace a gas boiler or change parts it may be cheaper to replace it, especially when it reached its lifespan. When changing parts, it may be more expensive to do due to the fact that they are old and the manufacturer does not produce as many of them for the old boilers anymore.

Gas boiler lifespan is the first reason for replacing it. You may also notice that your bills are increasing. This suggests a drop in efficiency which will be quite common for old boilers to be dropped to 70% as opposed to the new boilers with 90% efficiency. You may experience more obvious signs of a malfunctioning boiler where you may hear noises, notice leakage, pressure drops, pilot lights going off or heating issues.
