1) What is a tankless water heater?
Tankless water heaters are compact in size and provide a steady flow of hot water for as long as you need it. Rheem tankless gas water heaters are more energy efficient than conventional water heaters, because the tankless models eliminate the need for re-heating stored water.
2) How does the Rheem tankless water heater work?
A conventional tank-style water heater stores hot water, and heats the water 24/7, whether you use it or not. The new generation Tankless Technology Water Heater from Rheem only heats water on demand. When the faucet is opened, the water flows through the Rheem Tankless Water Heater, which heats it to the temperature you’ve digitally set. When the faucet is closed, the Rheem Tankless Water Heater senses the command, and goes to standby mode.
3) Can it be installed in the same place my old hot water heater was installed?
As long as enough combustion air is provided, Rheem Cartridge Heater tankless water heaters can be installed in a utility room, garage, basement, attic, or placed on an outside wall. Plus, they can be installed in locations where a storage water heater may not fit. The Digital Temperature Controller can be mounted in any room.
4) Are tankless water heaters energy efficient?
Yes, tankless water heaters are very energy efficient. The Energy Factor, EF, of all Rheem tankless water heaters is over .81. By comparison, a standard tank type water heater has an EF of around .62, so you can see that they are inherently more efficient than a storage type water heater.
5) Is a tankless water heater more energy efficient than a tank?
Rheem tankless gas water heaters are more energy efficient than conventional water heaters, because they eliminate the need to maintain a large supply of heated water. A Rheem tankless water heater operates only when hot water is needed. Regardless of whether you currently have a conventional electric or gas water heater, the Rheem tankless will save money on your energy bills. In addition, every Rheem tankless water heater qualifies for up to a $300 [tax credit?]
6) What is the Energy Factor for the RTG-42 series water heaters?
Answer: 0.83
7) What is the Energy Factor for the RTG-53, RTG-74 and 199 series water heaters?
Answer: 0.82
8) Does this mean tankless water heaters have lower operating costs?
A higher EF is only one of many reasons why tankless water heaters cost less to operate. A Rheem tankless water heater has no standing pilot light, no stand by loss, and the burners modulate to maintain maximum efficiency.
9) How do I ensure that I select a tankless water heater in the appropriate size for my home?
It’s as easy as 1-2-3! If your home has only one bathroom, a Rheem tankless RTG42 series water heater provides an ample supply of continuous hot water for your needs. If your home has two bathrooms, a Rheem RTG-53 series water heater provides an ample supply of continuous hot water for your needs. If your home has three bathrooms, choose a Rheem RTG74 series, which can supply up to 3 showers simultaneously. Homeowners with 3 or more bathrooms and/or large volume multi-head showers should consider linking (manifolding) 2, 3, or more of our tankless water heaters together.
