High Efficiency Gas Furnace Condensate Drain Freezing

However you need to make sure the system is operating properly.

High efficiency gas furnace condensate drain freezing.

A high efficiency condensate furnace can save you lots of money on your heating bills. These pipes direct condensation that collects during the heating process out of the heater and usually outdoors. Since the drain taps into the exhaust system leaving it open to the air would allow for a potential exhaust flue gas leak in the living space which is a big no no. The main difference between a conventional furnace and a condensing furnace is the heat exchanger technology used to extract heat from the combustion process and exhaust the combustion gases.

Condensate drains on the high efficiency condensing units were freezing where the drain pipes terminated outside the house. Additionally the inducer motor would suck air through the drain if it weren t trapped which could. In the northern united states it s important to make sure the condensate pipe won t freeze up during winter when you re installing a new furnace especially if you re installing a high efficiency furnace as these models produce. As the condensate forms in the exhaust pipe it should flow back into the unit where go through tubes in the unit and then out the unit from a smaller.

With the pipes blocked the condensate backed up into the furnaces where safety switches shut the units down. If the condensate from a high efficiency furnace leaks out of the pvc pipes or if the pipes are not draining the condensate correctly you could experience damage to your home and you may not.
