Build Show Live 2026 Registration
Steve Baczek takes us inside a high-performance home to break down a SpacePak air-to-water heat pump system designed for efficiency, comfort, and long-term flexibility.

This build uses two SpacePak heat pumps, hydronic buffer tanks, small-duct high-velocity air handlers, and over 9,000 square feet of radiant floor heating to deliver heating, cooling, dehumidification, and system redundancy through one adaptable HVAC platform.

The episode covers why air-to-water heat pumps can reduce refrigerant lines inside the home, support electrification and solar-ready design, improve comfort through hydronic heating and cooling, and help future-proof a home as HVAC technology and refrigerant regulations continue to change.

Watch more from The Build Show for building science, HVAC design, heat pump technology, radiant floor heating, hydronic systems, and high-performance home construction.

Huge thanks to our episode sponsor, SpacePak.
