Why Is My Heater Leaking Water?

January 10, 2020

If you have found out that your heater is leaking water, take action. Finding water around the heater can indicate that there is a problem that could lead to a dangerous malfunction of the unit. In this situation, you are encouraged to have an HVAC professional inspect the situation. A thorough inspection by a professional can result in the identification of the problem as well as effective repairs.

Here are some things to keep in mind about a heater that is leaking water.

What Type of Heater Do You Have?

An HVAC professional will narrow down the issue when he knows what kind of heater you own. There is a different between a high-efficiency and standard-efficiency furnace. The culprit of a leaking heater is usually condensation. Some furnaces are more prone to cause condensation than others.

High-Efficiency Furnaces

If you own a high-efficiency furnace, the cause of the leak has to do with the way this particular kind of unit operates. Since it extracts heat from combustion gases for a longer period of time, when the gas cools, it turns into condensation. Although there is a drain, if it is not draining properly, there is something wrong with the drainage.

Whole-House Humidifier

Another cause of the leak from your heater could be the whole-house humidifier. The humidifier could be leaking inside the furnace. If water is falling out of the furnace, then the issue is serious.

Internal Drain System

When the rest of the furnace is operating as expected, but the condensation is leaking out instead of draining, there could be a clog in that drain. If that is the case, an HVAC professional will unclog it for you.

Secondary Heat Exchanger

The worst-case scenario is a faulty secondary heat exchanger, which would require replacing the entire furnace.
