Boiler leakages are usually a symptom of an underlying problem. Some of the problems that lead to boiler leaks are serious and require the immediate attention of a contractor, some call for replacement of parts of the boiler, while for others, a simple tweak is enough to solve them. The following are common causes of boiler leaks that you should know:
Switching a boiler on and off usually subjects it to temperature changes that cause rapid expansion and contraction. This usually puts a lot of stress on the boiler's body. Over time, this pressure can cause cracks or splits to develop on the boiler's surface. And when these cracks/splits grow deep enough, they can cause leaks.
Cracks on a boiler are a sign of extreme wear and tear of the entire boiler. You can decide to patch it up, but it won't be long before more cracks or splits develop. Replacing the boiler is therefore a prudent financial alternative.
Loosened joints and damaged seals
There are different tubes, pipes and fittings that make up the boiler system. These parts are usually joined, together and to the boiler, using connectors that create a watertight bond at the joints. However, since these joints are usually exposed to hot water, and then to a cold environment when the boiler isn't running, they tend to expand and contract, something that usually loosens the bonds at the joints. Water may then leak from these joints. Tightening the screws and bolts that make the joints is usually enough to solve this problem.
Seals are designed to make the boiler water-tight. They however cannot do so when they wear out. As a result, high pressure water from the boiler might be able to squeeze through them and thus causing boiler leakages. This is a problem that can only be solved by replacing the damaged seals.
Boilers usually handle hot water. This usually causes a buildup of immense pressure within the boiler. Since continued buildup of pressure can cause the entire boiler system to explode, manufacturers usually design boilers with a pressure outlet whose main purpose is release any excess pressure. However, in the course of relieving the system, this pipe can cause water leaks and may thus leave puddles of water around your boiler.
Trying to solve this boiler leakage problem by sealing off this pipe is a bad idea because it would lead to the buildup of excess pressure in the boiler, causing it to explode. What works is simply reducing the pressure in the boiler – although you may want to check the pressure gauge to confirm that your boiler pressure is actually high.

Hi there, my name is Marissa Sonder. I would like to use my site to talk about the different types of furnaces available for residential and commercial applications. Growing up, my school had an actual boiler room that provided heat and hot water for the entire building. All of the students loved to go down to the boiler room and learn about all of the components down there. Although many buildings have moved on from this old piece of equipment, I would like to discuss its use in detail on this site. I will also talk about modern electric, natural gas, propane and oil furnace systems. Thanks for coming by.
