Trenches are dug to accept a horizontal slinky ground loop collector as part of an installation by Hero Renewables. The solar electric panels could help to offset some of the GSHP’s running costs
Whether you need an off-grid heating solution or simply want to power your home in a more sustainable way, fitting a renewable system could be a good option. One popular technology is the ground source heat pump (GSHP). This works by taking low-grade heat from the earth and converting it into usable energy at a higher temperature for space and water heating.
In many ways, a heat pump operates on the same principle as your kitchen fridge – just in reverse. The appliance is typically hooked up to a closed-loop heat collector system, buried in the ground where temperatures reach an average of around 12°C thanks to the sun’s rays. So GSHPs effectively make use of solar energy; hence why they’re considered a renewable resource.
