Overview
Heating water on demand and circulating it back to the fixtures, this Rheem Prestige condensing tankless heater burns natural gas and exhausts through PVC pipe. The recirculation pump learns usage patterns so hot water is supplied when needed.
Choose it for a large home where hot water must reach several bathrooms at once and arrive quickly at the tap. The limitation is installation, which requires a professional and venting runs that must stay within the listed pipe limits.
Who it's for
A homeowner replacing a tank heater and willing to hire pros for venting and gas work. The low flow activation suits small draws at a single sink. A small apartment or low demand home may not need this much capacity.
Pros and cons
- Built in recirculation pump
- Low emissions burner listed
- Flame sensor and overheat cut off
- Leak detectors for gas and water
- Professional installation required
- Natural gas only as titled
- Warranty terms conflict across listing
Performance notes
A condensing design pulls extra heat from the exhaust, which is why it vents through PVC and is rated for efficiency. Usable output depends on inlet water temperature, which the description says governs how many bathrooms it can serve. The recirculation pump brings hot water to fixtures without long waits.
