Signs You Need a New Boiler

Boiler is 20+ years old

Aging boilers lose efficiency and become unreliable. Modern units are 20-40% more efficient.

Rising energy bills

Older, inefficient boilers drive up heating costs significantly each winter.

Frequent repairs

Multiple repairs per season indicate it's more cost-effective to replace.

Uneven heating

Some rooms too hot, others too cold—your boiler can no longer distribute heat properly.

Visible rust or leaks

Corrosion and water leaks signal the heat exchanger may be failing.

Strange noises

Kettling, banging, or gurgling sounds indicate serious internal problems.
