Simplification and function identification

Hi, please spare sometime to help if following simplification and function identification is appropriately attempted

Observation

Fall in sales of Heat pumps

Explanation of an observation

A paradox

Less energy is converted into greater work

Facts: How Heat pump works

Facts: How Heat pump performs two contrasting functions?

Heating

Cooling

Rhetorical question

Is it really a problem?

Solution to a problem

Extra thermal energy + Electric input = total Output

Genuine problem:

As outside temperature decreases (Winters), Heat pump heating efficacy falls

Inference:

As outside temperature increases (Summers), Heat pump hrating efficacy increases

Explanation of problem

Author’s conclusion

Unfortunately, Its Latter that is the real problem
