A.O. Smith GPVL-50 ProMax Power Vent Gas Water Heater

We love the ProMax unit. It’s an efficient and also effective power vent water heater that uses gas as opposed to electricity, making running it less expensive to operate.

It also provides an impressive energy efficiency rating of .7, and the hot surface igniter works more efficiently than a standard pilot.

The 3-position blower also allows for optimal flexibility during installation, and it comes with a popular 50-gallon tank.

      What Are Power Vent Water Heaters?

      Gas water heaters emit carbon monoxide. This gas can become dangerous if not expelled from the home properly, especially if breathed by someone in the house. 

      Gas water heaters provide two fumigation options: 

      1. Power ventilation 
      2. Direct ventilation

      Power ventilation leads gas horizontally out through a specialized pipe system using an electric fan. Direct ventilation leads the gas upward through the existing chimney. 

      Power ventilation requires an additional power source not attached to the water heater to power the fan, while direct ventilation does not require an additional power source. 

      What Are The Different Types of Power Vent Water Heaters?

      Power vent water heaters come in two main types: tank and tankless. Conventional tank systems store water in the tank and keep it heated with a pilot light until it is needed. 

      Tankless options heat the water instantly, so a tank isn’t necessary. Tankless systems take up less space and save money in utilities, but they cost more upfront. 

      How Do Power Vent Water Heaters Work?

      Power vent water heaters send incendiary gas outside of the home as a safety precaution. An electric fan transports the carbon monoxide through a ventilation tunnel outside to dissipate into the air. During the ventilation process, the water heater uses the excess heat from the gas to help heat the water. 

      Power vent water heaters use either type of pipe system:

      • single-pipe system 
      • two-pipe system

      A single pipe system actually consists of two pipes (one inside of the other), but it appears as one pipe. The internal pipe safely transports carbon monoxide outside while the outer pipe creates airflow. Singles pipes systems are the simplest solution. 

      A two-pipe system uses two pipes. One pipe transports combustible gases while the other one creates airflow. If the pipes run vertically, the pipes should come to a 90-degree angle with each other. 

      If the pipes run horizontally, the pipes should slope downward slightly to reduce condensation build-up. Two pipe systems provide the best heat distribution. 

      Are Power Vent Water Heaters Worth it?

      Benefits

      Power vent water heaters provide multiple benefits compared to direct vent water heaters. Some of the benefits include:

      -Flexible Installation/Placement

      Power vent water heaters provide ventilation in multiple directions, and the system creates its own ventilation system instead of relying on the chimney placement. Power vent water heaters also have long pipes, making them preferred when placing a water heater away from the wall. 

      -Better Ventilation

      Direct vent power heaters fail from time to time and produce a backdraft. Backdraft occurs when gas doesn’t make it outside but changes direction back into the house. Luckily, power vent water heaters rarely experience backdraft, improving air quality in your home and keeping people healthy. 

      Disadvantages

      Of course, power vent water heaters also have some downsides to consider before you make your purchase, such as:

      -Noise

      Power Vent water heaters can get noisy when running. Water heater blankets may help place the water heater in a secluded part of your home.  

      -Electricity

      Power vent water heaters use gas to power the water heater and electricity to power the fan. You must install the water heater near an electrical outlet and pay for both gas and electrical usage (even if running the fan only costs a couple of dollars a year). 

      Plus, if the electricity goes out, you can’t use the hot water heater unless you have a generator, even though it’s gas-powered. 

      What Do You Look For In The Best Power Vent Water Heaters?

      You have decided that you want a power vent water heater because you prefer a gas water heater and want flexible ventilation options. You still have a lot of water heaters to choose from. 

      Which power vent water heater will work best in your home? Consider these factors to make your decision. 

      Appropriate Size

      You need to pick the correct sized water heater. If opting for a tank system, 50 gallons should provide enough hot water for up to three people. 80-gallon tanks can provide enough hot water for up to six people. 

      Getting a water heater too small for your home can lead to cold showers, and an excessively large water heater can severely affect your home’s efficiency. Oversized water heaters also heat up too quickly against the product’s design, causing damage. 

      Tankless systems generate instantly hot water that remains hot for as long as you run it. However, when you use multiple hot water sources, the system may not generate enough water for all faucets and appliances. 

      Consider how many things may be running at one time and add them up to decide how many gallons per minute you require. 

      Efficiency

      Buying a new water heater allows you to purchase a product with better efficiency ratings than your old water heater. Every water heater has an efficiency rating based on its output in comparison to the energy it uses. 

      All EnergyStar-rated traditional gas water heaters must have a rating between .67 – .95, with the higher rating indicating better efficiency. Tankless water heaters have much higher efficiency ratings. 

      Efficient products use less energy and therefore don’t cost as much to operate. Using less energy also means the electric factories won’t need to work as hard and put as many pollutants into the air, so it helps reduce your carbon footprint and looks attractive to green-focused future buyers. 

      Space

      Do you have the necessary space for a giant tank? If you have a giant tank already, could you do something more productive with that space?

       If you do opt for a tank, do you have specific size requirements in the area the water heater belongs? You should measure height and width to ensure your choice will fit. 

      Tankless options take up much less space than water heater tanks. They look better and fit more places. However, is the extra cost worth the slight increase in the appearance of your basement?

      Final Thoughts On Power Vent Water Heaters

      Power vent water heaters provide a perfect ventilation system for homes with gas water heaters not accessible to a chimney. Both tank systems and tankless options make it easy for you to place your water heater where you want while still providing ventilation. 

      Remember, carbon monoxide can pose a real threat. There have been cases where people have unfortunately died from CO2 poisoning due to faulty water heater operation. For this reason, we recommend not only choosing a highly rated power vent water heater, but taking additional steps to help insure your safety. 

      Added peace of mind can be achieved by placing a CO2 detector near the water heater. Depending upon the location of your unit, both battery and outlet detectors are available at a very low cost.
