Our take on the Rheem RTGH-95DVLN-3 RTGH Series Super High Efficiency Condensing Tankless Natural Gas Water Heater for Indoor Installation

The Rheem RTGH-95DVLN-3 is a condensing tankless natural gas water heater rated at 199,000 Btu/h for indoor installation. It fires only when hot water is called for and delivers continuous whole-home hot water, with no tank to run out. Condensing operation recovers heat from the flue gases, so it needs a condensate drain and is typically vented with plastic pipe. It suits larger homes with high simultaneous demand, but the gas meter and line must handle the full input, and it competes with other high-efficiency condensing units on efficiency and venting flexibility rather than on tank-style simplicity.

Questions and answers

Does this unit need a condensate drain?
Yes. As a condensing heater it produces condensate that must be routed to a drain per the installation manual.
Can it be vented with PVC?
Condensing models are commonly vented with plastic pipe as specified in the manual. Follow the listed venting requirements for length and termination.
Will my gas meter support 199,000 Btu/h?
Not always. Check that the meter and gas line can supply the full input before installing, or the unit may not reach rated output.
Is it for indoor or outdoor installation?
Indoor only. It needs appropriate venting and clearance to combustibles as the manual specifies.
What maintenance does it need?
Periodic flushing with an isolation valve kit removes scale, especially in hard-water areas. Annual service is typical.
Does it work during a power outage?
No. Tankless units need electricity for controls and ignition, so hot water stops when power is out.
