What is a Ground Source Heat Pump?
A ground source heat pump is a highly efficient heating and cooling system that utilizes the constant temperature of the earth to provide heating, cooling, and hot water for residential and commercial properties. Also known as geothermal heat pumps, these systems harness the natural thermal energy stored in the ground to provide reliable and eco-friendly comfort.
The way a ground source heat pump works is by extracting heat from the ground during winter and transferring it into your home or building. During summer, the system reverses the process, extracting heat from indoor air and transferring it into the ground, thereby cooling your home or building.
Ground source heat pumps consist of three main components: the ground loop, heat pump unit, and distribution system. The ground loop is a network of underground pipes filled with a mixture of water and an anti-freeze solution, which absorbs heat from the ground and carries it to the heat pump unit. The heat pump unit then compresses and circulates the heat to a higher temperature, which can be used for heating or domestic hot water. The distribution system, typically made up of radiators, underfloor heating, or air handlers, distributes the heat throughout the property.
