  Hot Water for Your Home in Any Season

The PrecisionTemp 550NSP-EC NG 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 Penetration

The 550NSP-EC NG 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 Flexibility

With 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 POWER

With 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the 550NSP-EC NG 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 Natural Gas.

With higher efficiency and 55,000 BTUs, the 550NSP-EC NG produces more hot water than traditional water heaters.

Without a tank to keep hot, many people report that they use up to 50% less natural gas. Homeowners love the lower operating costs and fewer fill-ups.
