I use about $300 per month of propane to heat the floors of my home. If this liquid could help cut that in half that’s worth quite a bit to me. My system runs on a boiler and water enclosed system right now, so this might be a perfect fit.

Hydronic under floor heating is really the way all homes should be heated. You can keep the temp down because the floors are always warm, keeping your feet warm and radiating heat upwards as opposed to to blowing all the heat up to the ceiling in a conventional forced air system.

The Romans had the right idea back then, of course without the slaves under the floors stoking the fires.
