A process for the extraction and recovery of bitumen from oil sands using deionized silicate solutions. The first heat exchange loop uses a first heat transfer fluid that is passed through a compressionevaporation refrigeration cycle to cool a refrigerated space and to collect waste heat, and then pumps that heat transfer fluid to a remote heat pump in the winter where the waste heat is used to provide warm air. The interface includes a second terminal coupled to a component within a second power domain.
