Review on RecPro RV Tankless Water Heater: On Demand Hot Water, Gas-Powered & Remote Control - Black by Michael Tarlue

We replaced the 6 gallon 2 way tank water heater that originally came in our travel trailer with this unit. After having it installed for a couple weeks, we have a list of both pros and cons.Pros:-Direct fit replacement for the Dometic/Atwood 6 gallon tank style heater. I didn’t have to make a fillet panel or anything for the outside of the trailer.-Does a great job at providing continuous hot water and maintaining the set temperature (there are a couple caveats to this in the cons)-Built in freeze protection works very well-Pretty quiet inside the trailer. You can definitely tell it’s on, but it’s less noisy than I thought it would be.-Pretty straightforward installation. Including the run to Lowe’s (more on that in cons) it only took me 2.5 to 3 hours to swap. I used the power from the LP gas switch on my control panel to supply 12v, so I have an additional kill switch to the one behind the access door.Cons:- Outside, it sounds a bit like a hairdryer on full blast. Thankfully our neighbors in our current campground are far enough away that it doesn’t bother them.- Doesn’t come with a T&P relief valve. Between the valve itself, and the tee and nipples to attach it to the outlet side, that ran me another 60 bucks at Lowe’s. RecPro, please start including this in the box. I’d rather pay another 15-20 upfront to have it included.-This unit is very finicky with the water flow and maintaining temp. The sinks are low flow enough that the heater can keep up with one at a time. However, the shower valve being fully open or both sinks being used is too much water flow, and the temperature may barely break 90 regardless of setting. Also, turning on the cold water too may cause a pressure drop enough to kick the heater off altogether. For this reason, we set the desired temperature on the controller and only open the shower hot valve a maximum of 3/4ths.
