Belonging to the new generation of ground source heat pumps, the NIBE F1145 is more efficient and, thanks to a highly intuitive control panel, more user-friendly than ever. It extracts heat from one of three sources - the rock under your land, a nearby water source or the earth under your lawn- and uses the energy to heat your home’s water-based radiators and hot tap water. It can reduce your energy costs by up to 80% (which means a dramatic reduction in both heating bills and CO2 emissions). NIBE F1145 is suitable for heating single and multi-family houses and industrial buildings.
