High Efficiency Noritz Tankless Water Heaters

Noritz tankless water heaters San Diego CANoritz  tankless water heaters combine the high efficiency of condensing technology with the comfort and savings of hot-water recirculation. A circulating pump inside the water heater keeps hot water close to the outlet, minimizing the wait and, therefore, the waste of unused potable water down the drain. Saving water, in this case, is doubly beneficial, because recirculation also avoids wasting the energy used to heat that water.

Using the integral digital display on the front of the water heater, homeowners can program the recirculation system to operate only when needed, with a precision down to the hour. An alternative, “auto” setting allows the system to quickly “learn” a household’s water-usage routines and automatically control the recirculation loop activation times, allowing for immediate hot water when it is needed most.

High efficiency for larger homes: Part of the Noritz ecoTOUGH™ Series of gas-fired residential tankless water heaters, the NRCP98-DV and the NRCP1112-DV have an Energy Factor of 0.95 for both natural gas and LP gas. These ratings are more than 10 points higher than that of a comparably sized, conventional tankless unit, and approximately 30 points higher than a standard, tank-type gas-fired water heater.

How recirculation system works: Recirculation is accomplished through a combination of an integral pump and temperature sensor and the home’s water-distribution system. The recirculation control works by monitoring the temperature of the water exiting the heat exchanger inside the water heater.

  • When exiting water reaches the maximum cutoff temperature, the recirculation pump shuts off, which also shuts down the burner.
  • Both remain off until the water temperature falls to the minimum cutoff — or there is demand for hot water — at which point they reactivate until the maximum cutoff level is attained again. Homeowners can choose whatever minimum cutoff temperature best meets the comfort and energy-saving needs of their households.

 

Warm water returns to the tankless unit from the various outlets in a home via one or more recirculation loops. The maximum loop run from the tankless unit is 200 feet for 1/2-inch pipe; 500 feet for 3/4-inch pipe.
