A Geothermal Heat Pump and Hydronic Radiant Heating Can Work Together

A geothermal heat pump and hydronic radiant heating are a matched set for efficient household comfort. Geothermal uses the unvarying latent heat just below the surface of the earth as a source of warmth in the winter. This clean, economical alternative is four times more efficient than combustion-based heating such as natural gas. Hydronic radiant heating utilizes hot water to turn the subfloor of your home into a radiant heat source for gentle, consistent warmth. Here’s how the systems work —and work together.

Geothermal

Year-round temperatures just six feet underground never vary much from 50 to 55 degrees. A geothermal system harvests this heat with long, U-shaped loops of high-density plastic tubing buried in shallow trenches or deep bores. As the tubing circulates heat-absorbing fluid, latent heat picked up from the earth is conveyed to the geothermal heat pump where it is multiplied by a compressor to temperatures sufficient to warm the home.

Hydronic Heating

Installed under the subflooring of your home, a hydronic system incorporates a grid of tubing circulating hot water and radiating warmth upward into the room. This heats objects and people through gentle convection and conduction, without the blasting hot air of a conventional forced-air system. Hydronic heat is more efficient because warmth radiates more consistently and stays lower in the room instead of accumulating at the ceiling.

Geothermal Hydronic Radiant Heating

A geothermal heat pump with a desuperheater can also heat water for circulation through a hydronic floor heating system. The desuperheater is a secondary heat exchanger that captures surplus heat from the heat pump and transfers it to water pumped into a water heater storage tank for use in the hydronic system. The desuperheater option is typically incorporated into a multifunction heat pump that consolidates heating, cooling and water heating functions into a single unit.
