Air to water heat pump technology is steadily gaining traction. When a heat pump’s coefficient of performance is maximized, energy efficiency and resiliency benefits are substantial. How can engineers, designers and installers effectively apply this emerging technology to high thermal mass floor heating applications? Which commercial systems are good candidates for this type of design? Hydronics expert John Siegenthaler, P.E. will detail the approaches that can best utilize this technology.

You'll learn:
→ Do all air to water heat pump systems need buffer tanks?
→ How does the thermal mass of a floor slab compare to that of a buffer tank?
→ What is a simple way to control a heat pump supplying a heated floor slab?
→ What are the benefits of using constant circulation in “garage-type” floor heating systems?
