Does the water heater affect the furnace?
Indirect water heaters can be powered by gas, electric, oil, or propane, and operate like direct water heaters. However, instead of having a heating mechanism inside the tank, it uses the heat from your furnace or boiler.This pipe circulates hot water from your boiler to a heat exchanger within the water heater.
Can you vent a hot water heater with PVC?
PVC is fine. As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters. They work by sending a huge amount of air in with the flue gases that it decreases the temperature of the exhaust going through the vent enough that it will not comprimise the vent.
How hot does water heater vent pipe get?
If a water heater is set to store water at 140 F to minimize Legionella bacteria growth, the flue gas temperature will be about 160 F when the heater is new. As scale builds up and the heater efficiency falls off, the flue gas temperatures can easily increase to over 350 degrees F.
Is a water heater and furnace the same thing?
Water heaters don’t heat your home. They do provide hot water. Boilers use water to heat your home. Furnaces heat the air and blow it into your home.

Is a water heater part of HVAC?
Water heaters are actually part of your plumbing system, not your HVAC system, because their purpose begins and ends with the temperature of the water supplying your faucets, showers, dishwasher, and washing machine.
Is water heater connected to heater?

Does a furnace need water to run?
Although a furnace doesn’t use water to run, special high efficiency furnace produces condensation during combustion.It’s this second combustion chamber that allows high-efficiency furnaces can produce more heat energy from their fuel. The furnace then vents the vapor out of the system.
What is the proper way to vent a gas water heater?
The venting must be vertical or upward sloping so that the hot exhaust rises up through the venting to exit your home. Making sure that your home has a properly working vent system is imperative when installing a standard atmospheric vent with your water heater.
Can a direct vent water heater be vented horizontally?
Compared to atmospheric, direct-vent water heaters offer more installation flexibility because they can vent horizontally. They also operate more quietly than their power-venting counterparts.
Can you vent two water heaters together?
exit vent would be fine. Thanks! Double the size of a single vent. Two exhausts flues, one from each tank, at 3 inches for each tank, equals 6 inches when combined.
What are the two PVC pipes coming out of my furnace?
Direct-vent (two-pipe) system: The two-pipe system is most common in home heating applications. It provides a direct intake vent that brings outside air to the sealed combustion chamber with one pipe, while a second vent pipe provides sealed venting of exhaust gases back to the outside of your house.
Is the vent pipe from the water heater supposed to be hot?
Heat from a gas water heater vent is normal. Even triple wall pipe will get hot enough to burn to the touch. Carbon Monoxide is odorless, you didnt describe the odor.
