Heat Output and Flow
As I mentioned previously, the flow rate of the RTG-64XLP will depend on various factors both inside and outside your home. Generally speaking, however, you can expect to receive at least 5 gpm.
It’s also doubtful that you’ll notice the difference between 6.4 and 6.8 gpm, so flow rate shouldn’t be a big concern in your final purchase decision. It’s solid.
As for heat, the normal maximum of the RTG-64XLP is 140°F, but it can be programmed to reach 180° if need be. This is more than enough to enjoy a hot bath or really scald your pots and pans.
One thing you should be aware of is that the RTG-64XLP doesn’t kick in until the flow rate reaches a minimum of .26 gpm. This isn’t a problem for most homeowners, but it’s a number to consider along with the rest.
You’ll find the RTG-64XLP relatively easy to install. Again, it must be done outdoors, but it involves the same wires and circuits as an indoor unit, so there will be no surprises there.
Here are just a few of the tools and supplies you may need for installation:
- Water heater connector
- Ground lines
- Amp breakers
- Pipe cover
A remote controller and 10-foot thermostat wire are included with your purchase, so you won’t have to worry about those.
If you have any questions or concerns about installing your unit, talk to a trained Rheem technician.
I’ve already spoken a little about the pros and cons of this unit, but for clarity’s sake, let me spell them out. You’ll want all the information on hand when you make the final decision about whether or not the RTG-64XLP is the right tankless water heater for you.
- Solid, hard-working natural gas unit
- In the middle tier of affordability
- Low NOx
- Must be installed outdoors
- Flow rate might change with simultaneous usage
- Minimum flow rate of .26 gpm
The Final Verdict
Do you worry about the fumes of a natural gas tankless water heater? Then the RTG-64XLP is the perfect choice for you. Out of five stars, I’d give it a solid four; while it does have certain components you’ll need to keep an eye on, it’s no more work than your regular water tank used to be.
You don’t have to take the word of a stranger on the Internet, however. Look up the Rheem RTG-64XLP on Amazon and see for yourself how much customers love it!
