With the same amount of electricity, heat pumps produce three times more hot water than electric heaters because they absorb free air heat from the surroundings.

Heat pumps run at high efficiency as long as ambient temperature is range from 15ºC to 40º.

“Today, the solar panel energy collection efficiency is still pretty low. For most conventional solar panels, the efficiency is between 15 to 20 per cent. The question is, can we increase the efficiency beyond 25 per cent?”
