hey everyone.....i will be doing a snow melt system for a 40' x 20' driveway....and a 20' x 4' walkway along with the stoop at the front entrance.....are they any design manuals for this...pipe size , loop lengths water temp,controls...etc....??....and customer would like to use existing Navien combi boiler with heat exchanger for this application or would it be better with its own boiler?? thanks PAUL S

    Snow melt

    Paul,

    The attached manual has great design info.

    You are going to face some challenges with the Navien option.

    When snowmelt systems fire up they will take all the energy you throw at it.

    If you connect to a heating system you have to limit how much it can take.

    The tekmar 667 is expensive but works well in these situations.

    Personally, I would use a triangle tube boiler for the snowmelt and not use a heat exchanger at all.

    667

    The 667 can be set to limit the difference between the supply and return delta t on the snowmelt. You can effectively limit the amount of energy the snowmelt can use.
