Ducted Open-Loop, Water-Source Heat Pump – Existing Homes

A ducted open-loop, water-source heat pump is a highly efficient electric heating and cooling system. It uses traditional air ducts and room registers throughout a home to distribute warm or cool air. New systems are much more efficient than electric furnaces, electric baseboards, electric ceiling cable or electric wall cadets. They use a deep outdoor water well to absorb heat during winter, then move that heat into the home. They dissipate heat from the home back into the water well during summer.
