Ground To Water Heat Pump

Looking for a sustainable and efficient way to heat and cool your space? Look no further than the ground-source heat pump, also known as a geothermal heat pump! This innovative system harnesses the stable temperature of the ground or groundwater, serving as a reliable heat source in winter and a heat sink in summer.

Comprising of a ground loop, heat pump unit, and distribution system, the GSHP is a powerhouse of energy efficiency. The ground loop, buried underground or submerged in water, circulates a fluid (typically a mixture of water and antifreeze) to absorb or release heat from the ground.

Installation options abound, from horizontal loops in trenches to vertical loops drilled deep into the ground, or pond/lake loops submerged in bodies of water. Whatever the configuration, GSHPs offer unparalleled energy efficiency, reduced operating costs, and minimal environmental impact compared to traditional heating and cooling systems.

Suitable for residential, commercial, and industrial applications, GSHPs provide versatile heating and cooling solutions. From space heating to space cooling and even domestic hot water heating, GSHPs have you covered year-round.
