When Chen Xin and the researchers left the room where the geothermal heat pump was installed and came to the SWAT team's cafeteria, the enhanced heating effect of the geothermal heat pump was already noticeably felt. Although the temperature was still cold, there was a more noticeable rise in the room's temperature.
Before Chen Xin upgraded the geothermal heat pump, people here looked as if they desperately wanted to stick to the radiator to warm themselves. But now, having switched from water heating to air heating, they were merely gathered around the radiator, and there was a clear sense of comfort in their demeanor.
This is quite understandable. Water heating uses a boiler or heat source to heat the water for heating, usually at a temperature of around 60~80°C, which is a temperature one can touch directly without feeling very hot.
