An air to water heat pump falls into the generic category of air source heat pumps. 

Unlike a generic air source heat pumps which extracts heat from the air and transfers it to either air or water, an air to water pump specifically extracts heat from the air to deliver to the water in your wet central heating system or hot water cylinder.
