boiler agent heat loss utilization projects


Heat Pumps – Analysis - IEA

In 2020, electric heat pumps still met no more than 7% of heating needs in buildings globally, yet they could easily supply more than 90% of global space and water heating at a lower CO 2 emissions level – even taking the upstream carbon intensity of electricity into account – than condensing gas boiler technology (which typically operates at 92-95% efficiency).
