    en.wikipedia.org/wiki/LO-NOx_burner

    Gas heaters with emission problems are flued and inherently lose substantial energies in the form of hot flue gases to the atmosphere. In addition, the choice of placement of flued heaters is greatly impaired due to flue installation restrictions. In contrast, dedicated low emission gas heaters do not require a flue system.

    en.wikipedia.org/wiki/Tankless_water_heating

    A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

    en.wikipedia.org/wiki/Selective_catalytic_reduction

    Ammonia flow is in general controlled based on NOx measurements taken from the gas stream or preexisting performance curves from an engine manufacturer (in the case of gas turbines and reciprocating engines). Typically, all future operating conditions must be known beforehand to properly design and tune an SCR system.

  7. Condensing boiler - Wikipedia

    en.wikipedia.org/wiki/Condensing_boiler

    Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
