  2. Condensate pump - Wikipedia

    en.wikipedia.org/wiki/Condensate_pump

    Condensate return pump. In industrial steam systems the condensate pump is used to collect and return condensate from remote areas of the plant.

    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.
