The "NW System" utilizes existing snow-melting pipe wells to extract geothermal heat, which is then used as a heat source for building air conditioning and snow melting, allowing for the use of geothermal energy at a low cost. Recently, the utilization of geothermal energy has been linked to CO2 reduction, and the government is also focusing on it as a national policy, providing subsidy programs. However, the enormous initial investment costs have been a barrier. However, by using this system, the most expensive cost associated with geothermal heat extraction, which is the drilling of geothermal wells, can be reduced. Additionally, compared to conventional electric air conditioning, electricity costs can be saved by 60% for cooling, 30% for heating, and 40% on an annual basis. 【Features】 ■ Reduced well drilling costs ■ Significantly lower electricity costs than usual ■ The U-pipe heat exchanger for geothermal heat extraction incurs no maintenance costs for a semi-permanent period ■ Less noise than oil boilers, leading to significant CO2 reduction ■ Short construction period, varying based on piping distance and site conditions, but approximately one week, etc. *For more details, please download the PDF or feel free to contact us.
