Waste Heat Recovery - US Department of Energy

The heat pump receives heat from a low­temperature source and rejects it at a higher temperature. The heat pump uses waste heat plus an additional 0.22 million Btu of electrical energy to provide 1 million Btu of useful heat, while the boiler requires an input of 1.25 million Btu to provide 1 million Btu of steam heat.
