A snowmelt system may extend the life of the concrete, asphalt or under pavers by eliminating the use salts or other de-icing chemicals, and physical damage from winter service vehicles.Systems are available in two broad types based on heat source: electric resistance heat or heat from a combustion or geothermal source delivered hydronicly (in a fluid). Arguably, electric snowmelt systems requires less maintenance than hydronic snowmelt systems because there are minimal moving parts and no corroding agents. Most new snowmelt systems operate in conjunction with an automatic activation device that will turn on the system on when it senses precipitation and freezing temperatures and turn off the system when temperatures are above freezing. These types of devices ensure the system is only active during useful periods and reduces wasteful energy consumption. A high limit thermostat further increases efficiency when installed in conjunction with the automatic snow melt controller to temporarily disable the system once the slab has reached a sufficient snow melting temperature. Some building codes require the high limit thermostat to prevent energy waste. Though their total environmental impact depends on their energy source.
