There are alternatives to ground source heat pumps for a new build domestic property. First of all much better wall insulation, floor and roof insulation, triple glazing and last but not least, airtightness. When the fabric of the building is sorted then installing a mechanical ventilation with heat recovery system will apparently, if you read about Passivhaus buildings, reduce heating requirements to a very small percentage of a current conventional build house. Only then would it be necessary to consider air source heat pumps, solar thermal systems and other heating systems.
