The presence of a 3- or 4-inch PVC pipe indicates a gas water heater, because the fan and motor inside the water heater force exhaust created by the gas out into this vent and outside. Electric water heaters do not have a venting system as there is no exhaust.

How are water heaters powered?
A vast majority of homes have conventional tank-type water heaters, which are powered by either gas or electricity. When hot water is called for at a faucet or appliance, heated water is pumped out the top of the tank and through the home’s hot-water supply pipes.
How do you know when a hot water heater is going bad?
5 Water Heater Failure Signs You Should Never Ignore
- Lack of Hot Water. Is your shower water lukewarm?
- Popping or Rumbling Noises. Water heater noises are another common culprit of water heater failure.
- Cloudy Water. Does your water look cloudy?
- Leaking or Faulty Pressure Relief Valve.
- Leaking Tank Water.
How does a water heater work electric?
An electric water heater works essentially the same way as a gas water heater. It brings cold water in through the dip tube (1) and heats it using the electric heating elements (2) inside of the tank. The hot water rises in the tank and is moved throughout the home through the heat-out pipe (3).
What is the motor on top of water heater?
Smith power vent gas water heaters are equipped with an electric blower fan that is installed on top of the water heater, which requires an electrical outlet to be close to the water heater. The blower pushes the exhaust and excess heat through the exhaust venting.
How do I tell if my water heater is gas or electric?
Start by looking for an access panel on the side of the water heater. If you remove it and see a blue flame, that’s a pilot light, which only gas models have. Connected pipes are also indicators of gas, while an electric water heater will simply have a cord going into the top or side of the unit.
Are water heaters electric?
While there are some water heaters that run on solar energy, oil and propane, the most common water heaters are fueled by either electricity or natural gas. With electric water heaters, the water is warmed up when it comes in contact with large coils extending into the tank.
What should it cost to replace a water heater?
Water Heater Installation Cost Installing a water heater costs between $817 and $1,596, or an average of $1,206, including the unit and labor. Tankless heaters cost about $1,000 to $3,000. Water heater prices range from $300 to $2,000 or more for the unit alone while plumber labor runs $45 to $150 per hour.
Can water heaters explode?
Water heater explosions are terrifying, and they can happen. Anything that causes excess pressure on your water heating system, such as a poor anode rod, or a lot of sediment buildup, can all cause your water heater to explode. A gas leak can also cause your water heater to explode because it is a tremendous fire risk.
How long do water heaters last?
It would be nice to know when the time is right to replace your water before it springs a leak and causes an inconvenience or worse yet, damage to your home. Typically a residential hot water heater lasts between 6 and 13 years. Beyond 12 years, you are on borrowed time!
Why is my electric hot water heater not working?
No Power or Gas If an electric water heater is not producing hot water, it could be a simple problem like a blown fuse or tripped circuit breaker. Additionally, some electric water heaters have a circuit-style safety switch located near or on the thermostat.
How do you test an electric water heater?
How to Test the Element
- Shut off the Power.
- Remove the Metal Covers.
- Remove the Insulation and Plastic Covers.
- Locate the Heating Element.
- Verify the Electricity Is Off.
- Check the Heater Element With Your Multimeter.
- Reassemble the Water Heater.
What is inside an electric water heater?
The tank of a water heater consists of a steel outer jacket that encloses a pressure-tested water storage tank. This inner tank is made of high-quality steel with a vitreous glass or plastic layer bonded to the inside surface to prevent rusting.
What causes a water heater to backdraft?
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.
Do I need a blower on my water heater?
Does every water heater need ventilation? No —but as much as water heater technology has changed in recent years, combustion water heaters remain the most common. That is, the average water heater still burns fuel—be it natural gas, oil, or propane—and that fuel burning releases byproducts like carbon monoxide.
Why do water heaters have power vents?
Venting systems are necessary to prevent flue gases from accumulating in your water heater. These gases largely consist of water vapor and carbon dioxide. The vapor becomes acidic and needs to be released in order to relieve combustion pressure and prevent the water heater from exploding.
