The soil composition of each country is different, resulting in different heat transfer efficiency. For example, soil with a large sand content will have a better thermal conductivity, so the efficiency will be higher. 2.Where can heat pump units be used? Heat pump units are widely used, including various types of commercial machines specially designed for hotels, schools, hospitals, saunas, beauty salons, swimming pools, laundry rooms, etc.; there are also various types of household machines specially designed for families.  At the same time, it can also provide free air cooling, which can realize the whole year heating. 3.Can ground source heat pumps use group control system? This is feasible. If you are a project that needs a system to remotely control the heat pump, please tell us your specific requirements or the effect you want to achieve.
