Condensing tankless water heater

Intended for two-bath residences, the NRC711 gas-fired  condensing tankless water heater stresses high-efficiency and a lower carbon footprint with an Energy Factor of 0.94 for both NG and LP fuels. Available in both indoor and outdoor units, the NRC711 offers a compact design with: a heat exchanger that is three times as durable; all-new scale-detection software for more proactive leak prevention; and a built-in digital display to aid servicing. For the indoor direct-vent model, condensing technology permits venting with installer-friendly, three-inch PVC or CPVC pipe, which is less expensive than the Category III Stainless Steel venting required by conventional tankless units.
