Where do hot water tanks vent?
Direct Vent The exhaust gases and excess heat produced by your water heater are then vented back outdoors. A direct vent water heater uses special coaxial venting that has separate chambers for intake air and exhaust in a single assembled vent piece. The venting runs from the water heater through the side of your home.
Is a chimney liner required for a hot water heater?
The rules also state that orphaned water heaters vented into an unlined masonry chimney require the installation of a properly sized liner.
Can I vent my hot water heater out the side of my house?
Direct vent or horizontally vented water heaters are designed for installation where vertical chimneys or flues are not available or would be more expensive to install. The vents go directly through an outside wall, and can also bring in combustion air to the gas burner.
Can I vent my water heater horizontally?
Most tank-type gas water heaters are “atmospheric vent” type, and they are required to vent vertically and above the roof of a home. Two specialized types of water heaters, direct vent and mechanical vent (also called power vent), are exempted from this code requirement.
How far can you vent a hot water heater?
Power-vented natural gas water heaters use an electric fan or blower to push or pull combustion gases to the outdoors. This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents.
Does a hot water tank need to be vented?
In the US, it’s required by code to have an exhaust vent, or flue, connected to the top of the water heater. That flue has to take the exhaust gases up and out of the house. This type of water heater is called a “natural draft” water heater because it removes the exhaust gases without assistance by a fan.
Do all chimneys need a liner?
A chimney liner might not seem like an important part of your chimney, but in reality, it’s extremely important and improves the safety of your fireplace and home. Additionally, a chimney liner is required to be present to pass inspection for property transfer.
What happens if water heater is not properly vented?
A vent connector is the thing that takes the exhaust gases from the top of the water heater (draft hood) to the vent. If a vent connector isn’t properly installed, the potential for the water heater to backdraft increases.
Why is my water heater not venting properly?
The main reasons for backdrafting at the water heater are the poor vent installation and obstructions found in the vent pipe. This problem affects mainly the atmospheric gas type water heaters that use natural convection to remove the combustion products, known as exhaust gases.
How much does it cost to put a chimney liner in?
The average cost to have a chimney lined by a professional is going to be about $2500. Depending on the type of chimney liner, it could cost up to $10,000. The average DIY chimney liner installation is going to cost about $750 and could cost as high as $3000 for the material.

All water heater venting systems use a vent duct or pipe—also called a chimney or flue—to bring exhaust gases from the water heater to the outdoors.
What is a gas chimney vent used for?
They were designed and sized to vent very hot flue gases from old coal, wood burning, or low-efficiency gas furnaces. The exhaust gas temperature of modern gas furnaces and water heaters is much lower than past appliances because much more heat is harvested so you waste less money up your chimney.
Can a high efficiency furnace vent through a chimney?
A new high-efficiency furnace may now vent through a plastic pipe that exits a sidewall of the home, not the chimney. Thus, the water heater vent is now an orphan in the chimney.
