Radiant Floor Heating/Tiny house with radiant floor heating


Hi there!

There's a shell of a cabin-like structure situated on a custom-built trailer here in town that was built ten years ago an then abandoned in a storage facility. I'm considering purchasing it to convert into a tiny house. The owner installed Pex-AL-Pex piping, aluminum heat exchangers, reflective barrier, and isocyanate foam underneath the wood floor and said they are exactly the same as any modern hydronic system. I want to know if this sounds like a safe investment, as I may take off for a week at a time in the winter. The structure's radiant floor system has never been used and no water has been pumped through it yet. What are the chances of a set-up like this bursting in a cold winter if I am not around to keep the water heated? Do people put antifreeze in their Pex tubing to prevent winter-time disasters? What other concerns should I know about?


Hello Lisa.

I would have to have more information. Tube size, spacing, with insulation depth and insulation in walls, ceiling etc.

People do use antifreeze in radiant floor systems when absolutely necessary. We like to use freeze alarms as well. Sounds like a good candidate for one of our combi storage tank water heater systems.
