How a Heat Pump Works

This Old House plumbing and heating expert Richard Trethewey instructs Kevin O’Connor on the basic principles of how a heat pump works

This Old House plumbing and heating expert Richard Trethewey uses a mockup and props to show host Kevin O’Connor the mechanics of the latest state of the art heating and cooling system.
