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?

    We are not talking a “few degrees”, they are talking 1.5 degrees since some random time which is well outside the range of accurate temperature readings. 3 degrees more than now in even California could be lived with, curiously temperatures on the equator are often less than there, 3 degrees and another 500 ppm of CO2 would probably double world crop production, someone is seriously delusional, and it is not me! Do you know anything about plants, they feed on CO2, and respond to it as more food, more growth? This is normal horticultural practice, to get CO2 levels in greenhouses to 1500-2000 ppm to increase growth and therefore production, and shorten the growing season. 

    But you're talking about plants grown in a greenhouse, where it's temperature controlled, and there's a plentiful supply of water and feed.

    Most of our farmland is outdoors.

    Out in a field, no amount of CO2 will help if the plant is underwater because of a flood, or baked dry in a drought.
