Four ways to collect energy

  • Smart energy efficient shortcuts

    Air source

    There is no need to dig or drill your garden with an air source heat pump. Energy is extracted directly from the surrounding air in economic and environmentally friendly manner. Air source heat pumps are affordable, flexible and can easily be used to upgrade your existing heating system.

    Benefits:
    • Lower investment cost;
    • No impact on the ground;
    • No large plot needed;
    • Ideal for retrofitting. 

    Ground source

    The vertical ground loop collects solar energy stored deep below the surface. A hole is drilled into the bedrock and a pipe is installed into a depth of up to 200 meters. The precise depth depends on your house, the size of heat pump and the surrounding conditions. Due to the earth’s endless ability to capture and store heat, there is no limit to the number of homes in a neighborhood that can efficiently use this technology.

    Benefits:
    • Needs very little space for installation;
    • Minimal impact on the plot: can be placed in most gardens, however small;
    • The hole in the rock maintains an even temperature throughout the year;
    • Allows a passive cooling and fits any building.

    Horizontal ground loop

    The horizontal ground loop collects solar energy that is stored in the ground. The loop is buried about one meter below the surface and energy is extracted from the ground. The length of the loop depends on your house, the size of the heat pump and local ground conditions.

    Benefits:
    • Lower installation cost compared to vertical ground loop;
    • The coil in the ground maintains an even temperature throughout the year;
    • Allows passive cooling;
    • Can also be used to extract heat from lakes.

    Groundwater

    As the name suggests, a groundwater heat pump collects energy from the groundwater. The water is pumped up from a water borehole to a heat exchanger, where the energy is recovered. The water is then discharged back through another well. This solution can be the best choice when groundwater is readily available.

    Benefits:
    • Groundwater maintains a relatively high, even temperature, all year round;
    • Minimal impact on the plot;
    • Allows passive cooling.
