Why Is My Boiler Leaking Water?

Boilers have a few major advantages in the world of home heating: inexpensive and fast installation, quiet operation, high energy efficiency, and long lifespans. One of the reasons they last so long is that boilers contain few moving parts, so unlike furnaces or heat pumps, they won’t need frequent repairs due to wear and tear.

However, boilers do experience one repair issue that comes up more often than others: water leaks. In any system that uses water circulation to work, leaks are a possibility that must be addressed as soon as they occur. Modern boilers suffer few leaking troubles because of their sturdy manufacture, but leaks can still happen—especially if the boiler was improperly installed or doesn’t receive regular maintenance.

If you notice leaks in your boiler, call up Greater Comfort Heating & Air Conditioning, Inc.® for help. We perform all types of heating repair in Hebron, KY, and we can patch those leaks for you and find out what’s causing them.

Here are some reasons your boiler might develop leaks:

Corrosion: Rust and corrosion is the super villain of any device where water meets metal. If your boiler starts to develop corrosion inside its tank or along its pipes and around its valves, the metal will weaken and water can start to leak out. Repairs can sometimes remove small corroded patches or replace the corroded parts, but if the problem spreads too far you may need to have the tank replaced.

High pressure: A boiler should maintain steady water pressure (an expansion tank helps with this task), but a buildup of limescale and calcite along the pipes or inside the tank will drive the pressure higher and trigger leaks in numerous places. If the pressure release valve becomes blocked, it will also cause a pressure spike. You’ll need professionals to seal the leaks and remedy the increase of pressure to prevent further problems.

Poor initial installation: If you inherited a boiler with your house, it may have gotten a shoddy or amateur installation. The usual trouble we see from poor installation is leaking because of bad soldering along the copper pipe fittings. You may not need a complete reinstallation—experts can often perform repairs that will get the boiler into proper shape—but this is sometimes the best option.

When leaking begins, you need to act fast to stop it. Not only do leaks often warn about other problems in the boiler, but even the smallest water drip can cause structural damage to your home and encourage the growth of mold and mildew.
