  • How to design high-efficiency hot-water systems for hospitals

    Oct 24, 2016 · The piping feeding the condensing boilers connects to the main HWR prior to the discharge point of the heat-recovery chiller back into the main water system. This allows both the heat-recovery chiller and condensing boilers to receive cooler HWR, thus maximizing the efficiencies of both systems.Learn More

  • Heat Recovery Systems Booklet - Clayton

    Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers. The following table shows the potential for heat recovery from boiler blowdown. …Learn More
