Initial geological considerations before installing ground source heat pump systems [PDF]

open access: yes, 2009
The performance of an open- or closed-loop ground source heat pump system depends on local geological conditions. It is important that these are determined as accurately as possible when designing a system, to maximize efficiency and minimize ...
