Is Rust a Sign That My Boiler Needs Repairs?

Your boiler uses water to heat your home, but it is made to withstand the effects of rust. For rust to develop, there has to be enough oxygen present in the air in addition to the water; boilers are made to be as air-tight as possible, so rust shouldn’t be an issue. If you are seeing rust and corrosion on your boiler, it is time to call a technician as the rust is most likely the result of a problem somewhere in your system.  The trained and certified technicians at Boehmer Heating & Cooling are available around the clock when you’re in need of quality boiler repair service in South Hills, so if you are seeing significant rust on your boiler, call us today.

Sacrificial Anode

Manufacturers of boilers understand that rust development is a potential issue with any boiler. This is why every boiler comes equipped with a component called a sacrificial anode, also called a sacrificial rod. A sacrificial anode is placed at the top of the water tank. It is made from a highly active metal alloy that corrodes faster than the metal of the tank, so it “sacrifices” itself ahead of the tank. But should the anode completely corrode and not be replaced, the rusting process will move on to the tank itself.

Problems Caused by Rust

Rust and corrosion are never good for any whole-home system; here are a few ways it can be problematic for your boiler:

  • Development of leaks – if rust has developed in an area like your water tank, the expansion tank or on piping, water leaks can develop. This will lower the pressure in your system and cause heating problems in addition to potential water damage.
  • Problems with water temperature – rust acts as an insulator. If significant rust develops on your water tank or heat exchanger, the system can overheat. Additionally, the higher temperature can increase the pressure in your system, which can cause problems.

Maintenance Is Great Prevention

One of the best ways to ensure that your boiler isn’t rusting is to schedule annual maintenance. During a maintenance appointment, you system will be thoroughly inspected and the sacrificial anode will be checked and replaced if needed.

Rust is never a good sign on a heating system. If you are seeing excessive rust on your boiler in South Hills, call Boehmer Heating & Cooling today to schedule a service appointment.
