This is typically flown out of a pvc pipe that comes from the furnace and drains into the floor drain in your furnace room.
Gas furnace water drain.
Shove the tablets into the drain pan opening and push them in farther using a dowel or long screwdriver.
This adds up to a lot of water vapor.
However if this tube becomes clogged or if the drain on your floor becomes it can cause water to backup and leak out of.
The condensation is then draining onto or around the area of your house where the furnace is.
But if there is an issue or a clog anywhere in the condensate line or drain water will begin overflowing and leaking from the furnace and onto the floor.
After the water stops flowing turn off the boiler drain and disconnect the garden hose.
High efficiency furnaces naturally produce condensation as a by product of the natural gas burning.
Some high efficiency furnaces may use a condensate pump to push condensation toward the proper draining area.
Most furnaces will have at least 2 internal drains typically one for the heat exchanger and one for.
Whether you use radiators or radiant heating the process of draining and refilling the boiler is relatively simple.
Additionally the inducer motor would suck air through the drain if it weren t trapped which could.
In order for the furnace to work properly that condensation needs to be drained out or else it would accumulate inside the heat exchanger inducer and venting impeding proper gas combustion product flow.
Check to see if the expansion tank a small barrel shaped tank located near the boiler has a drain on it.
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.
Remember to give the system time to drain and fill.
Problems with the condensate pump.
If the furnace is producing condensation during the winter the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit.
Fix the problem with chemical tablets and a larger drain hose.
These allow the furnace to extract heat from the gases for a longer period of time.
The condensate trap is absolutely mandatory for a high efficiency gas furnace.
These pipes run throughout your house and certain pipes even run outside.
That condensation then exits out your home through a drain.
Add new tablets monthly during air.
But a high efficiency furnace to extract more heat has 2 heat exchangers.
Unlike conventional water heating systems closed hot water boilers should only be flushed when operation problems occur.
A condensate pump is a small white box.
