Tankless water heaters are all the rage, as they allow you to have more space in your garage, utility closet, or even on your back patio. These units are able to be mounted to the wall and have no large, cylindrical tanks. If you are looking for a replacement unit or need a water heater for your new construction, consider the Rheem tankless.
Finances play a big factor in deciding which appliances you want for your home. Who doesn’t want a deal on energy savings? A majority of the Rheem tankless water heaters are listed as “high efficiency,” meaning they have an energy factor of 0.90 (90%) or above. While you may pay a bit more to purchase and install the tankless unit than a tanked one, the cost of usage and energy savings speak for themselves in the long run. Rheem attributes their high efficiency capability to the stainless steel heat exchanger in that unit, whereas the “mid efficiency” ones have a copper heat exchanger.
If you’re into controlling your thermostat with an app, Rheem’s tankless water heater EcoNet collection now allows you to control your home’s water system in the same way! Such a system assists you in saving more money (yay!) by monitoring water usage from across the house or country, and the app provides timely maintenance reminders. You’ve got the power in your hands. Unless you purchase the one model with the WIFI module included, the EcoNet accessory kit (SKU: REWRA630TWH) will need to be bought separately.
Indoor tankless water heaters have several venting methods, though the two most popular are direct venting (through the roof) or sidewall (horizontally out of the wall). Venting is oftentimes made easier by termination kits we have on our website (but these will have to be chosen by a certified installer, as venting depends heavily on local codes). On all models, you can use 2” venting with band connections; however, with high efficiency units, you can use PVC piping.
Other notable features for the Rheem tankless water heaters, depending on the model:
- Guardian overheat film wrap sounds like something you’d put over Tupperware when heating up your food—at least, it does to me. But this really is a covering that prevents the unit from reaching extreme temperatures
- Ultra-low NOx burners are meant to give off lower emissions, and they meet state/city requirements. Whether you need a unit that is ultra-low NOx or not will be disclosed by your installer. For example, if you live in California, you will most likely need this style
- Vent type varies based on the model. A majority of indoor units will be listed as “direct vent.” All outdoor units will not require any venting since it can pull from the outside air (and you don’t have to worry about the combustible air blowing back into the house)
- Some come with the re-circulation pump included, such as model/SKU: RTGH-RH10DVLN. This feature provides faster hot water at the tap without residents having to wait
- When sized properly, the Rheem high efficiency tankless water heaters in the RTGH series are designed for continuous hot water expenditure. People oftentimes choose tankless for this ability
- Many Rheem tankless water heaters come with high-altitude capabilities built in. Other competitors may have a high-altitude kit available, but these are rated for immediate use in those mountainous areas
- On the product page for these tankless units, there is a clickable link for an opportunity for a rebate through Rheem. This would go towards a utility company in your area. (Seeing a pattern here with Rheem tankless water heaters? Savings, savings, savings!)
- For large homes or even commercial buildings, you can pair these tankless water heaters together easily with additional components. For example, if you wanted two Rheem units, you would need the EZ Link Cable
Please visit our tankless water heater calculator to receive an estimate on the gallons per minute (GPM) you would need for your home. This takes into account how many fixtures—faucets, dishwasher, clothes washer, and showers—are utilized in the same span of time, as well as the temperature of incoming ground water. Each tankless water heater describes the “application,” illustrating how many showers could be supplied at the same time. While we have this resource online, it is always best to contact an installer in your area to determine the best one for your household.
