Can radiant heat be used for cooling?
Hydronic radiant systems can provide cooling, but with significant limitations requiring careful design to prevent condensation problems, while electric systems cannot cool at all, making radiant cooling a specialized application suitable only for specific climates and building types. Radiant cooling basics: hydronic systems circulate chilled water (typically 55-65°F) through same tubing used for heating. Removes heat through radiation and minimal convection. Provides gentle cooling without air movement. Limited to 20-30 BTU/sq ft cooling capacity versus 40-50 BTU/sq ft for forced air. Cannot handle latent loads (humidity). Requires separate dehumidification system. Works best in dry climates or with dedicated ventilation systems. Condensation challenges critical: surface temperature must stay above dew point to prevent condensation. Requires sophisticated controls monitoring humidity and surface temperature. Floor coverings affect performance – carpet prevents effective cooling. Insulation below pipes even more critical than heating. One condensation event can cause massive damage. Professional design absolutely essential. Not DIY friendly. Insurance concerns with water damage potential.
