Snow Melt System Calculator
Design hydronic snow melting systems per ASHRAE guidelines.
ASHRAE Snow Melt Classifications
| Class | BTU/sq ft | Application |
|---|---|---|
| I | 75-100 | Residential, Intermittent |
| II | 100-150 | Commercial, Continuous |
| III | 150-250 | Critical Safety Areas |
Design Guidelines
Minimum Glycol: 30% for freeze protection to -10F
Surface Temp: Target 35-40F during snow
Pre-heat: Start system before snowfall
Insulation: R-5 minimum below slab
