This is why a high efficiency furnace is also known as a condensing furnace, and a standard efficiency furnace is a non-condensing furnace. Why Is Hot Water Coming Up From The Overflow Pipe The overflow pipe is where the water passes through when the valve is open. However, if you have a high efficiency furnace, (90% efficiency), condensation will arise due to the addition of the second heat exchanger. Got the basics? So where does the water come in?Ī conventional furnace, also known as a standard efficiency furnace, does not produce water. That's how warm air is made!Īdditionally, if your furnace is struggling to turn on at the start of the cold season, consult our blog to learn more! This is where the air absorbs the heat and is then forced through your house's ventilation system to heat the house. Your water heater leaking from overflow pipe may be due to: Sediment accumulation in the tank. After this, the blower fan blows cool air from inside your home past the heat exchanger. The flue gases inside the heat exchanger are released outside through the exhaust pipe. This starts by turning on an ignition switch, opening the gas valve, and turning on the draft fan to create combustion. The water is splashing up on the wall so it must initially be running out but we have only ever seen it drip. We wake up (7-8am) some mornings to find a puddle on the ground under the overflow pipe from the loft.

If you’re finding water in your water heater pan, a leak due to deep internal corrosion is the worst-case scenario. This tubing always has a constant flow of dripping water. In most cases, you’ll need to completely replace this valve. If it’s wet, this is the source of your leak.

When the indoor temperature dips below the thermostat's set temperature, the thermostat sends a signal to the control board inside the furnace to begin the heating cycle. Basically, the overflow pipe from the cold water tank in the loft (I think) is dripping sometimes. Wipe a paper towel on the bottom of the downtube. For starters, lets dig into how your furnace works.
