need help and ideas with tiny home floor

RayB Member Posts: 1
My project is building an 8' x 20' tiny home office on a trailer. Have a 8' x 20' steel flat-bed trailer with light sheet metal flashing underneath. After I get all the holes figured out and cut, I will get trailer fully coated. Building with wood on top of the trailer.

Most likely building 2x4 walls with spray foam insulation. I'm really leaning toward a multi-wall polycarb roof for max natural light. Winter temps can hit 0-20F lows, but usually lows around 30-40F. Summers usually 60-70F, but can get hot, though I'm positioned in a nice half-shaded spot.

So who has economical, efficient ways to design, build and insulate floors. Thinking about radiant heat with thermafloor. Want to focus on heating fluid with 1kw solar pv, but have backups wood stove, propane stove, diesel generator. Also planning to add solar H2O panel to preheat water.

Any helpful thoughts or ideas would be welcomed. Thanks!

    Sounds a lot

    Looks like your going to a lot of equipment l would just invest in a 50 gallon water heater with side loops for radiant .

    Before I go with therma floor I would just use quick track.

    Or go with a navian combo unit.

    Sounds like a lot of money to spend on a throw away trailer.

    Fuel source?

    What do you have available and what does it cost?  How much DHW is needed?

    Ray's not the only one doing this

    Not sure how popular this is to do, but apparently Ray has company in this sort of thing.

    RV system

    I think Dennis Bellanti add radiant floors to his RV. About the same concept. As much insulation below as you can stand. Tight spacing on the tube, RV water heater to power with LP or a small electric wh

    If electric is an option, may as we'll use electric cable or mats and skip the hydronics
