Why Don't I Have Hot Water?
-
If the boiler is not generating heat, homeowners can blame one of several issues. Issues such as a defective thermostat, loss of electricity or lack of gas can cause the boiler to stop heating properly. The safety switch, burner or motor could also be off.
Is There Something Wrong with Circulation?
-
Boilers work by circulating hot water throughout the system. Homeowners can check the piping to see if the water is circulating. The pipes are supposed to be hot, so touch them lightly or with a thin cotton glove to protect your skin. Check all pipes, radiators and baseboard heaters. Lack of heat in any of these areas could indicate a circulation problem.

What Are Those Noises?

A boiler operating with noticeable noise could have problems. A banging noise could mean oil is being left in burn chambers causing sudden ignition; constant noise while running can indicate a dirty boiler that needs cleaning and servicing. Some noises are normal, such as pipe popping or snapping; in some cases, this is caused by normal expansion and contraction.
What Do Leaks, Rust or Burn Marks Mean?
-
Some boiler problems are visible. If you notice water leaks or see rust, boiler problems are probably present. Boiler tanks that show visible burn marks or soot can have dangerous gas leaks and should be serviced.
