FAQs

How do you calculate snow melting?

Snow melting can be calculated based on various factors such as temperature, solar radiation, and insulation. One common estimation is to use the degree-day method, which involves tracking the number of degree-days above freezing (typically 32°F or 0°C) to estimate snowmelt. The formula is:

Snowmelt (in inches) = (Degree-days above freezing / Constant) x Snow Density

The constant may vary depending on local conditions but is often around 4-5.

How big of a snowmelt system do I need?

The size of a snowmelt system depends on the area you want to cover, the climate of your region, and the desired melting rate. On average, a snowmelt system typically requires 50-75 watts per square foot to melt 1 inch of snow per hour.

How fast does 2 inches of snow melt?

The rate at which 2 inches of snow melts depends on temperature, sunlight, and other factors. In general, it can take several hours to a day or more for 2 inches of snow to melt at temperatures slightly above freezing.
