The system uses electricity to power the compressor but the system has an average Co-efficient Performance (CoP) of 1 : 4.
So is it really Free Energy?
Coefficient Performance – CoP = The ratio of energy used to create even more energy
1 unit of electricity equals 7 units of heat energy
1 : 7 in the summer
1 : 3 in the winter
In summer, for every unit of electricity use1d the system will deliver 7 times the amount of energy, whilst in winter, for every unit of electricity used the system will deliver 3 times the amount of power; thus delivering a CoP of 1 : 4.
Typically, on any sized system can save up to 80%!
