Precision Temp Floor Vented RV 550 NSP Tankless Water Heater
**The standard white finish is currently unavailable and all units will be shipped with polished finish aluminum.**
Identical to the RV-550, the RV-550 NSP is designed to be vented through a 2 inch exhaust pipe avoiding the large wall penetration used to install the RV-550. This Precision Temp model is the only all-season, floor vented, tankless water heater for cabins, tiny houses and RVs.
No Freezing Up, No Worries!
The Precision Temp RV-550 NSP tankless water heater utilizes patented VariFlame Control technology to deliver an endless flow of hot water in your cabin or tiny house.
No more running out of hot water in the middle of a shower. Whether you live alone or have a large family, no one has to take the blame for using the last of the hot water!
Hole In The Wall Vs No Hole In The Wall
The RV-550 NSP is vented through the floor where the traditional RV-550 is installed through the wall. This allows the RV-550 NSP to avoid through wall installation and make the NSP model truly an all season installation at the same time!
Show Me The POWER in Precision Temp
There's a bunch of power packed into this little unit. 55,000 BTUs to be exact making this unit the highest hot water output in the industry. Add the built-in freeze protection and this tankless water heater really delivers more than just hot water.
What About Efficiency on Precision Temp
With higher efficiency and 55,000 BTUs, the RV-550 produces more hot water, has no tank to keep hot, and uses less propane than than traditional water heaters by as much as 50%.
