If the heat exchanger has only 60% efficieny, then the energy loss is 5kW * 0.4 = 2kW. Where does the enrgy go? Energy cannot vanish magically, it must go into the ambient. I think even if the heat exchanger at this size (as visible in the video) has no insulation, it cannot lose 2kW. It is well isolated and the loss must be much lower. The output temperature delta of course is lower then te input temperature delta, but at the secondary circuit the flow can higher. A heat exchanger has always a loss of temperature, but this does not necessary mean a loss of energy. If the isolation against ambient is 100% perfect, then it will reduce the temperature but not loose energy, because the secondary flow must be higher than the primary flow. Peter
