Contact your local HVAC contractor.....these sytems are great! One must consider the size of the area they are heating and the money saved long term in snow removal expenses plus the safety factor in having the system. They not only have electric systems but also radiant systems

tape your joints of the foam board - sand migration

some recommend a blanket below the foam board that adds that much more insulation - although it's not needed

make sure the tubing is stapled to the foam board not tied to wire mesh, which used to be the way they did it. What would happen is that every time the system would turn on it would cause slight movement of the lines from the pressure on the wire which eventually would cut the tubing causing a leak
