[Construction Case 8] Nursery School Floor Heating (Geothermal Heat Pump Heat Source, Hot Water Type)
A case of renovation to hot water floor heating using a geothermal heat pump (HP)! Achieved a surface temperature of 28°C!
Here is a case study of floor heating installation at a nursery in Kariwa Village, Niigata Prefecture. Initially, it utilized electric storage floor heating powered by night-time electricity, but in response to changes in energy policy, it was upgraded to hot water floor heating using a ground source heat pump (HP) with a high coefficient of performance (COP). To maximize the high COP characteristic of the HP heat source, the outlet water temperature was set relatively low at around 45°C. However, to ensure effective heating performance, the installation combined highly conductive heating panels with copper pipes, which also have high thermal conductivity, achieving a surface temperature of 28°C. 【Case Overview】 ■ Kariwa Village, Niigata Prefecture ■ GeoHP ■ 864m2 *For more details, please refer to the PDF document or feel free to contact us.
