Can ground-source heat pumps provide domestic hot water?

Yes. Ground-source systems can be installed with desuperheaters that can provide you with about half of a typical home’s annual hot-water needs. A ground-source heat pump operating in cooling mode will typically store unwanted heat in the ground. A desuperheater will use that waste heat to pre-heat your hot water before it enters your hot water tank. A desuperheater add-on will cost around $1,800 but will cost virtually nothing extra to operate.
