More on the RTG-66XP

The Rheem Outdoor Liquid Propane tankless water heater can handle the hot water needs for a 2 or 3 bath house efficiently. And as far as cost goes, LP is much more cost-effective than electricity, so most buyers actually see a drop of 20% to 35% with this unit. And with many comparable units going for literally twice as much as the Rheem RTG-66XP, your immediate savings are as rewarding as your long term savings on your monthly utility bill. Let’s take a closer look and see just what the Rheem Outdoor LP tankless water heater has to offer.

The attempts to minimize the physical room taken up by tank systems, while also delivering enough hot water for 2 to 5 people without the need to fight over who goes last. And with a minimal flow rate of .26 GPM, this unit provides plenty of hot water, even if you need a small flow. The way tankless water heater systems work is by instantaneously heating the water piped from your cold water line. You simply have a cold input, hot output, LP line and thermostat. And the Rheem RTG-66XP handles the hot water needs of a 2 to 3 bath home perfectly.

At 180,000 BTU, you can get very hot water, so if you have little ones, make sure you ramp down the temp with the remote thermostat. Also, regarding the thermostat, a great feature of the Rheem RTG-66XP is the ability to override the high-end temps. Most water heaters are governed to max out at 120 degrees for legal reasons. But if you set this tankless system at 120, and then press down and hold the “temp up” button until 140 pops on the display, you can set it from 120 to 140. This is a good idea if you don’t have children, and like higher temps for a dishwasher, and a feature not every hot water has.

This particular unit lists a freeze rating down to -30 degrees Fahrenheit, and that should cover most homes, but you can cover with a plastic utility box or mount inside your garage or shed to allow for even lower temps. This is also an Energy Guide tankless water heater, and is rated at $223 average annual utility cost. That means it is also eligible for federal tax credits provided for energy efficient water heaters.

And this is a really small system. That means if you currently have a water heater that takes forever to get hot water where you need it, you mount this small, unobtrusive unit closer to the location you need the hot water, and you save money as well as keep from standing in cold water for 5 minutes waiting it to warm up.
