Leaking Hot Water Heating Systems

Even a properly designed and installed
hot water heating system can develop leaks.
Fixing them right away
can increase the lifespan of the system.
If you have a leaking hot water heating system, your robbing yourself of the longevity your boiler and all of the components can offer.

Hot water heating systems are supposed to be sealed systems. This means that once they are pressurized and purged of all the air, the water in the system stays in the system and no more need be added unless there is a leak.

When leaks occur in a hot water heating system, there is an automatic feed valve that replaces the water that leaks out with new water from your city supply or your well.

This new water also contains minerals and oxidants that will rot out the non-ferrous parts of a hot water heating system. This means anything not made of copper or brass is susceptible to decay from the added water.

Included is the boiler and any cast iron or black iron fittings, pump bodies, fittings and pipes. All of these system components are attacked when new water is added.
Normally the substances in the water that can harm the system are distilled quickly and settle to the bottom of the boiler where they will do no harm. Adding water constantly will defeat this distillation process and rot out the system quickly.

I've seen boilers begin leaking within six months of installation because leaks were never fixed.

To get the most out of your hot water heating system; be sure to fix any leaks immediately.
