Purchasing a matched system through HVACDirect and paying a typical **$1,500 to $3,000 for professional installation** may lower the estimated project total to **about $5,800 to $10,500**, including a planning allowance for standard materials, permits and disposal.

The Noritz NRCR Pro Series is a high-efficiency condensing tankless water heater designed for homeowners who want hot water faster. Unlike a standard tankless unit, the NRCR Pro includes a built-in recirculation pump that keeps hot water moving through the plumbing loop, helping reduce the wait at showers, sinks, and appliances. The guide notes that the system supports recirculation loops up to 200 feet with 1/2-inch piping or 500 feet with 3/4-inch piping, making it a strong option for homes where fixtures are far from the water heater. Both NRCR Pro models offer a 0.98 UEF efficiency rating, smart recirculation modes, Bluetooth app control, and a 15-year heat exchanger warranty. The NRCR92 is best for medium to large homes with moderate hot water demand, while the higher-output NRCR111 is designed for larger homes with three or more bathrooms and heavier simultaneous use.

It is the first tankless combi boiler in the industry to run both functions at the same time without compromising either, and it qualifies for Energy Star Most Efficient certification and state rebates that help offset the cost.
