Air Sourced Heat Pump.

Zoomup
A person today that I was talking to, that has had a new build home which was required by building regs. to have an air sourced heat pump for heating and hot water, complained that the system was slow to heat or cool as required. He said that he had to have underfloor heating installed. It was slow to warm the rooms on cold days. He recently had the system set to cool the rooms on the very hot recent days. But this morning was cooler and he required heating. Is this normal?

    It isn't just burning fossil fuels, or even wood, but also breathing. A normal breath is about 500 ml. About 4% of exhaled air is CO2 and we breathe about 14 times per minute. So that is 0.5 x 0.04 x 14 = 0.28 l/min or 150,000 l/year. That weighs about 300 kg. There are about 8 billion of us, so that is 2.4 trillion kg of CO2 per year.


    Then there are folk who chop down trees and so on, which reduces the world's capacity to "capture" the CO2. It seems that the more people there are, the more trees get felled.


    So IMHO, it's not just about green energy, it's about over-population.
