Heat of the earth core
Thermo pump installations
The thermo pumps connected to the earth do not generate heat. Due to the reversed refrigerating process the thermo pump , operated by an electric engine, withdraws underground heat (or the heat of the underground water or the heat in the reservoir)with a lower temperature level and takes it into another volume , as it evolves it at a significantly higher temperature level. That is against the nature law and can not be granted for free. The price is the cost for electricity for operating the pump, , which will “move” the earth (water) heat. Average the cost for electric energy for the pumps, towards the produced useful heat, is 1 to 4,8 which means that if the consumed power is 1 kilowatt , that the heating power will be 4,8 kilowatts.
If the temperature of the underground water is 12 grad Celsius and after passing through the thermo pump device is injected back in the soil with a temperature of 2grad Celsius , then each single cubic meter of water that has passed through the system will evolve useful energy of about `12 kilowatts. If a pump with a debit 10 liters per a second works ten minutes , then it will pump in the system 6m3 water , which means that about 46 kilowatts of heat energy will be transferred , which is equal to a heat generator (electric boiler for example) with a capacity of 270 kW, than the electric power , necessary for installation operation will be below 60 kilowatts.
The described technological process in the example uses the so called thermo pump system ”water-water”. It is one of the most economic systems for heating (relevantly for cooling in the summer).That system is even more effective , when electricity , required for the pumps is obtained on account of the sun, through photovoltaics or through wind generators.
