Power vent water heaters are more energy efficient, so they require less gas to operate. The lower energy consumption will save you some money, but probably not more than $20 a year, making this an added benefit, but not a deciding factor.

What type of water heater is most efficient?
Tankless heaters can be 24-34% more energy-efficient than regular water heaters for households that use 41 gallons or fewer of hot water daily. Tankless heaters can be 8-14% more energy-efficient for households that use around 86 gallons daily.
What is the difference between power vent and direct vent water heater?
The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe.
Why are power vents so expensive?
Cost: Because of the added fan/blower, power vent water heaters typically cost significantly more than their direct vent counterparts. You must also be mindful of additional costs that may arise, like the electricity to run the blower and/or additional piping you may require.
Can you put a power vent on a regular gas water heater?
Natural gas or propane hot water heaters are generally less expensive to operate than electric heaters, but installing a standard vent in a house without an existing chimney is expensive. It’s easier to run the vent if you install a “power-vented” type of natural gas (or propane) water heater.
What is the difference between point of use and tankless water heaters?
POS tank water heaters typically last 10 to 15 years, while tankless water heaters can last up to 25 years, providing a long stretch of time to save money on utility bills and still cover the cost of the POU heater and installation.
Why is tankless water heater bad?
In addition to high upfront costs, tankless water heaters have several other disadvantages compared to tank-style water heaters: they take longer to deliver hot water. the water temperature is inconsistent when multiple outlets are on simultaneously. they cannot provide hot water during a power outage.
What is the advantage of a power vent water heater?
Since a power vent water heater eliminates the potential for backdraft, they greatly lower the risk of carbon monoxide poisoning, although it is not totally eliminated. Energy savings is another benefit. Power vent water heaters are more energy efficient, so they require less gas to operate.
How long does a power vent water heater last?
Based on the manufacturer’s suggested service life, the life expectancy of a water heater is about eight to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
How much does it cost to install a power vent water heater?
Power Vent Water Heater Installation Cost An installed power vent water heater averages $1,050 to $5,000. They have more moving parts and require electricity to vent. Even if you use gas to heat your water, your water heater requires electricity to work.
How much electricity does a power vent water heater use?
Typically, a hot water heater that uses a tank will run for three to five hours per day. So, a 4,000-watt heater used for three hours a day at $. 10 per kWh will cost $1.20 per day, about $36.50 per month, or $438 per year.
Is a direct vent water heater more expensive?
When using a direct vent water heater, water is heated by the heat of fuel combustion. A direct vent system typically results in lower water heating costs, because the exhaust gases are vented vertically, with no extra power required as is the case with the power vent water heater.
Are power vent water heaters noisy?
Many people complain about power vent water heaters because they create too much noise. We’ve got a few ways to help you reduce the noise and keep everyone happy. There are many different ways you can reduce the noise; some are easier than others.
Can you vent a gas 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.
Does a gas water heater need to be vented?
All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. Since flue gases from the water heater are warmer than the surrounding air, they will rise naturally through a vertical vent pipe or chimney to the outdoors.
