The Ground Source Heat Pump (GSHP) system is extensively applied all around world for building heating and cooling. A new system type which uses foundation heat exchangers (FHXs) to reduce system capital cost has been suggested. This paper aims at studying the effects of different land covers on FHXs design lengths; consequently these affect the system capital cost. The FHXs are more applicable to rural areas since it requires enough space for laying the heat exchangers. In Chinese rural area, FHXs buried at 8 locations in 4 different cli-mates are investigated. In each location, the FHX design lengths under bare soil, concrete and vegetation are simulated. It is found that, in warm climates, land cover type has little effect on the results. In other climates, the FHX design length under bare soil and results under concrete are respectively 5.8%-18.1% and 15.9%-38.3% longer than the results under vegetation cover.
