In a trial of the idea, a network of polyethylene water pipes 25 millimetres in diameter has been buried below a section of private road in the UK. The pipes are laid in rows about 15 centimetres apart and at a depth of 12 centimetres, where the ground temperature is normally about 12 °C on average. In the summer this can rise to 25 °C.

None the less, that is very hot, especially considering that japan is an island and is at a high lattitude.
