Winterizing a hydronic system

in THE MAIN WALL
Would like any input into winterizing a building that will be without heat this year as it is unoccupide. It is a Hot water baseboard convector system with runs underground. So just draining is not going to remove all the water. We are a heating contractor who has never attempted this and would like to help out a good customer.

    Air compressor, blow out all zones and boiler. Just did my house upstate ny, kripplebush. Gets real cold up there.

    Got to agree

    If you blow out each run seperately as you would when you fill and let it run for quite a while, they should be dry. No different than irrigation guys do every winter here in the frozen North. You'll want to have a good compressor. I'm not a fan of shutting down a system if it's a home. Hope the owner understands the other implications of moisture, frost, etc. that can do lots of damage to the structure itself.
