    Thats kind of the backwards way of doing it...
    How long are the loops?
    Did you imbed them directly into asphalt?
    2000 ft2 is approx 300K btu.
    A condensing boiler would be a must IMO.
    You are going to need some pretty hefty piping.

    How we we quickly do you want to melt?  100 btu/sq ft would be the low end. Mod con, heat pump, or copper tube boiler
