It is proposed that in the near future most houses will be built using ground source heating instead of gas heating. I am fully in favour of such schemes, but given that, according to one estimate, an average house requires 300 - 700 square metres of land to accommodate the heat collecting pipes, in areas of high density housing (surely the largest sector) how can sufficient heat collecting pipes be accommodated. Given that an enormous quantity of heat would be extracted from the soil, what effect would the lowering of temperature have on the flora and forna in and on the soil? If the solution to these problems was to be the use of air source heat pumps, would the effect on the outside temperature lead to similar problems, ie more severe frost when wind speed is low.
