Designing a snow melt system is relatively simple if you follow some simple rules.
If properly designed and installed, most snow melt systems are a very effective and
inexpensive way to remove snow from sidewalks and driveways.

  Most snow storms in each area have very similar characteristics. In most areas the temperatures start above freezing, and it starts snowing at about +34 F. and stops at about +20. If you are designing a heating system for a house with a design temperature of 0 F. you can add 1000 sq. ft. of snow melt without increasing the size of the heating system, if you use a snow control that turns the snow melt off below 18 F.
  12" centers work well in both concrete and asphalt.  All loops need to be the same length to make the system work evenly.
  Although many snow melt systems are designed with polyethylene tubing we recommend only PEX tubing.               
  Snow melt systems need 50 to 100 Btu's per sq. ft. to operate properly. 
A low temperature start up, is when the temperature has been below 0 for several days and comes rapidly up to the twenties and starts snowing. In these areas you should use Polypropylene Glycol anti-freeze and use minimum  mixtures, (30%).
  Copper boilers are available that can be placed in the shrubbery next to the driveway, and with a automatic snow control, work well in medium sized systems.
  For asphalt systems, light equipment can be driven over the tubing by running water through the tubing until all the air is removed, then closing off both ends and maintaining at least 60 pounds pressure.   
   
  Never use an on-off switch to control a snow melt system. Always use a simple wind-up timer or a automatic snow control. A snow melt control will turn the system on when it starts snowing  and off when it stops, and cost less than 200.00$.  See http://www.networketi.com

HeatTrak Mat     A portable electric mat for snow melting!    www.heatrak.com


The HeatTrak Mat
is designed to lay over any flat surface requiring snow and ice removal. In addition to melting snow and ice, the mat's non-slip rubber surface acts as a traction mat, further preventing potential slip-and-fall accidents. The HeatTrak Mat is designed and built with grommet holes to make securing the mat both simple and effective.
