I purchased the RV 550 nsp in 2017. Had to do some troubleshooting with Gary, who was extremely helpful, to determine that my propane line was undersized for the unit to run optimally. Upgraded my LP line to 3/8″ ID and the heater is cranking hot water in middle of winter here in Colorado. Very satisfied with the unit, and very impressed with the level of excellence I have found at Precision Temp!
We’ve had this unit operational in our remote cabin western Canada at 800 meters ASL, 52 deg. Lat.. since 2013. It has operated each summer June through September flawlessly. Having sufficient and constant water pressure and volume is important, as is sufficient voltage to operate blower fan. We drain and fill with RV antifreeze without fail to protect the heat exchanger. Don’t “trickle” your hotwater. Turn it full on, wait, then turn down or blend if required. I’d buy it again….but why? I have a great one already.
After owning the 550 NSP EC since about February, I can review that after a few minor hiccups that were primarily my not understanding the way the system operates versus a conventional hot water tank, this water heater is the the best thing I’ve ever worked with on a daily basis.
Very well made and whisper quiet.
Thank you to Fred and Gary for their knowledge and support. ?
I highly recommend this company and their products and customer service.
Stay safe and well everyone.

Hot Water for Your Home in Any SeasonThe PrecisionTemp RV-550 NSP EC tankless water heater utilizes our patented VariFlame Control technology to deliver an endless flow of hot water for the ultimate in pampering for you and your family.
No more waiting for a small water tank to refill and no more quick, cold showers. Whether you’re just one person or a whole family, endless hot water is there for your enjoyment.
No Sidewall PenetrationThe RV-550 NSP EC is vented through the floor and out of the home with a 2” exhaust pipe. No sidewall penetration (NSP EC) means you don’t have to cut a large opening in the wall.
Ultimate Floor Plan FlexibilityWith a smaller footprint and floor venting, the RV-550 NSP EC allows for floor plan flexibility as never before. This can free up cabinet space and provide for less complicated installation.
The Proof is in the POWERWith 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the RV-550 NSP EC delivers on-demand, continuous hot water.
The heater operates only when the hot water outlet is turned on. The VariFlame control system then keeps the water temperature constant, regardless of the flow rate or incoming water temperature.
More Hot Water. Less Propane.With higher efficiency and 55,000 BTUs, the RV-550 NSP EC produces more hot water than traditional water heaters.
Without a tank to keep hot, many people report that they use up to 50% less propane. Homeowners love the lower operating costs and fewer fill-ups.
