Noritz 11.1 GPM Residential Built-In Recirc. Pump Liquid Propane Indoor/Outdoor Tankless Water Heater Max 199,000 BTU/H

Noritz NRCP series heaters offer the latest cutting edge technology in tankless water heaters. The NRCP features an internal pump that can be used in two different modes. External mode, combined with a return line, can keep the water in the pipes warm resulting in lower wait times for hot water. Internal mode, which does not require a return line, will keep the water within the unit warm to reduce the traditional delay between water demand and the startup sequence. This unit is equipped with heavy-duty 304° stainless steel heat exchanger for superior thermal transfer as well as excellent resistance to scale formation. Noritz NRCP series heaters can be vented using 2-Sch. 40 PVC pipe and operate with as little as 3.5 in. water column on the incoming gas line. These features contribute to a relatively low installation cost. All brought to you by Noritz America, the world's largest producer of tankless water heaters.
