Tell me again! You are seriously saying you bring in warm air or heat from the ground indoors to heat a room? An example I know from observation is in winter outside it can be 0°C and my bedroom is 10°C with no heating switched on. You say freezing cold air is brought into a compressor into a house which is already warmer than the freezing air being brought in? Why not recirculate the already warm air at 10°C into the heat pump and let that heat the room? Why start from zero when you can start from 10? Where is this heat from outside? Zero degrees C. This just sounds like an expensive con job to dig up your garden to put pipes in and make it complicated!
