Causes of Boiler Leaks

Tuesday, January 14th, 2014

Leaks are among the most common cause of boiler malfunction, lowering the pressure and preventing the boiler from heating the your home comfortably. They can also be quite subtle: it’s not enough to simply look for a puddle because some leaks are so small that the water simply evaporates. Trained heating technicians know how to hunt down the causes and make repairs accordingly. Here are some common causes of boiler leaks. For more information or for boiler repair, call the Fairfield, OH heating repair experts at Bartels Heating & Cooling.

  • Rust. Rust and corrosion can affect any part of the boiler, especially an older one. Rust around seals and fittings is common, but depending on the boiler, it can pop up anywhere.
  • Bad circulator pump. The pump helps the water move around the boiler system, allowing it to heat your home. When the pump won’t work, the water doesn’t move and the pressure can build up. All that pressure can work on weak fittings and seals until a leak develops.
  • High pressure. Along those lines, excessive pressure from any source can put severe strain on the boiler’s components and result in a leak.
  • Cracks in the body. As your boiler ages, it may develop hairlines cracks and create a leak in the core unit. This is serious because it usually means having to replace the entire boilers.  Cracks are especially prevalent in older boilers that have been around a while.
  • Seals and joints. Depending upon their age and condition, seals and joints are the most obvious places to look for leaks. Unlike the pipes themselves, they don’t have to corrode to create a breach. A poor fitting can be enough to cause a leak (though such fittings are usually easy to fix).
