What is the role of a condensation trap in a hot water system?

A condensation trap plays a crucial role in a hot water system by collecting the water that condenses from flue gases. When combustion occurs in a gas appliance, some of the byproducts include steam and other gases. As these gases cool down while passing through the flue, moisture can condense out of the gases. The condensation trap captures this water, preventing it from pooling in the flue system, which could lead to complications such as water damage or inefficient operation of the appliance. By managing this condensed water effectively, the trap helps maintain proper operation and safety within the hot water system. This function is vital for ensuring that the exhaust system remains functional and reduces the risk of corrosion or blockages that could arise if condensate is not adequately handled.
