Radiant heating to detached workshop with no drain.

I'm building a detached workshop without a drain/plumbing. How can I deal with the condensation from the planned radiant floors system's propane boiler. It will be built on a foundation that will be insulated and backfilled. I live in MN so winters are a big thing here. Too old to run 5 gallon buckets around on the ice/snow. Thanks

    I have a number of places here in NH I have run into the same issue.... No Drain for condensate.
    I have been drilling a hole through the exterior wall and pitched a 3/4" section of pex tubing outside at a 45* angle.
    I have about 2" outside and about 6" inside.
    I then run the 3/8" vinyl drain from a condensate pump into the top of the tubing going outside. It dumps it all at once and has never frozen.

    You're still building it? Put a drain in. A workshop without a drain is akin to a truck without 4 wheel drive in MN.
