Frequently Asked Questions
Click on question to reveal the answer.
1. What is FVIR?
It means Flammable Vapor Ignition Resistant. An ANSI (American National Standards Institute) standard went into effect in July 2003 that will prevent a water heater from igniting flammable vapors outside the combustion chamber. This helps to protect homes.
2. Are all FVIR water heaters the same?
No, they are not. The consortium of manufactures agreed on flame arrestor plate technology to create the new generation of FVIR water heaters. Early in the development, Rheem researchers at their Montgomery labs discovered that flame arrestor plate designs might be vulnerable to the effects of lint, dust and oil - LDO. Rheem urged the ANSI standards be reviewed. As a result, the ANSI standard now includes testing for reliability in LDO environments. Throughout development, Rheem engineers have been highly attentive to the role LDO robustness will play on product reliability and consumer satisfaction.
3. What is the Heat Pump Water Heater all about?
The HPWH has a 10-year tank leak warranty and a 10-year parts warranty. It also has a first year in-home labor warranty. This water heater uses heat pump technology to achieve a 2.0 efficiency rating. (Residential gas is approximately 0.62; and residential electric is approximately 0.92). The HPWH is also Energy Star Compliant and may provide you with tax savings.
4. How can I determine which water heater is right for me?
Choosing a water heater is based on your family size and how much hot water you will use in one continuous hour. We call it Peak Hour Demand.
5. You have a water heater with a LIFETIME warranty?
Yes, we do. It is called the Marathon. The Marathon is a special water heater that has a seamless blow molded polybutene inner tank. It will not rust. The several inches of foam insulation give it up to 0.94 energy factor. Tank sizes range from 15 gallons to 105 gallons to fit any household need. Once you purchase this water heater, the lifetime warranty is extended to the original owner when installed in a residential application.
6. I need to vent my gas water heater several feet away from an outside wall. Which product is best for me?
There are a couple of products that may work in your application. The Power Direct Vent is a seal combustion, direct vent water heater that may be installed up to 60 feet away from the homes outside wall. We also have a standing pilot Direct Vent that will vent up to 4 feet from the outside wall.
7. Do you make water heaters designed for commercial applications?
Yes we do. We have a full line of standing pilot, intermittent spark, direct vent, sealed combustion and high efficiency commercial water heaters. Our Xtreme models will provide up to 756 gallons of hot water in an hour; and recover the tank contents in as little as 8 minutes! You can select from an electric model or gas model.
8. How can I find a local installer of Rheem Water Heaters?
We have a special application to help you. You can find a plumber near you by entering your zip code.
9. Is there an upgrade to your normal tank leak warranty?
Yes there is. During the installation of your new water heater, you can add this kit and receive an additional four year tank leak warranty. This kit will fit most Rheem residential gas and electric water heaters.
10. What is temperature rise?
Temperature rise is the difference between the set temperature of the unit and the temperature of the incoming ground water. For instance, if you set the temperature of the unit to 120 degrees F and the incoming ground water temperature is 60 degrees F, this is a 60 degree temperature rise. The lower the set temperature, and the higher the incoming ground water temperature, the more hot water flow the unit can produce and vice versa. If sized correctly for your application, the unit(s) should not have a problem producing enough flow for your hot water needs.
11. Why does it take so long to get hot water?
The wait time to get hot water is primarily a function of the distance between the water heater and the point of use. Our Water Heaters (Rheem) is producing hot water within a few seconds of first water flow from a cold start. However, you must purge all the cold water out of the pipe between the Rheem water heater and your point of use. For example, if your kitchen sink is 50 feet and the water flow rate is 1 gallon per minute than it will take 90 seconds for hot water to reach your sink. Having to wait for hot water after you open the tap is a pain. It also wastes water and energy. There are several ways to lessen this problem. First you should consider the location of your water heater. You have 3 choices to eliminate the wait time or waste of waiting for hot water: 1. You could install a re-circulating pump and line that keeps hot water following through a loop in your water system and then through your Rheem water heater. 2. You could lessen the energy waste by running the pump on a timer. 3. You could add a cold water line re-circulating system to your common points of use. This is a system that will circulate water from your Rheem water heater to a point of use by utilizing your cold water line as a return. This does not shorten the wait period for hot water but it does eliminate water waste and will not increase your energy cost like standard re-circulating systems.
12. Does Rheem manufacture an electric tankless water heater?
Yes. The Rheem tankless electric products are ideal for point-of-use applications to get instantaneous hot water on demand. All Rheem tankless electric products are energy efficient and designed to fit almost any location.
