Which statement best distinguishes recovered heat from waste or surplus heat?
What is the correct order of the heat-recovery hierarchy?
A factory reports 5 MW of rejected heat at one operating point. What additional evidence is most important before estimating annual recoverable energy?
Which sequence correctly narrows a waste-heat opportunity from the broadest to the most realistic potential?
What does “direct use” of recovered heat mean?
Why can return-line integration be disadvantageous?
Which statement about thermal storage is correct?
What is the most important protection principle for data-centre heat recovery?
Which is a key technical risk for wastewater heat recovery?
A heat-recovery system shows “source available”, an active export command and zero flow. What is the best first response?
A source can provide 2 MW whenever it is operating. If availability is 90% of the year, what is the maximum source-side annual energy before network-demand limits, storage losses and equipment downtime?
Applied case: a data centre offers 2 MW of source-side heat at 30°C to a 70/40°C district-heating network. Which recommendation is most appropriate at initial screening?
