Radiant Floor Heating/Hydronic Radiant Floor System for mobile home


City: W. Coxsackie, State: NY, Ele: 166FT  Stage: Design
We have a 14 x 76 1976 Mobile home we have completely gutted. So far
we have re-framed for new energy star windows and doors, wrapped entire house in housewrap, insulation is R23 Roxul in walls and under floor. We want to install a radiant floor system with 2 zones,
Basically the only 2 rooms that are not open are the bedroom on the end, and bathroom next to it.  The rest of the place is open. I have laid out all in CAD the 1/2" tubing on 8" centers all runs lead from and to the addition that will house the heating system as well as the water system and electrical.  We want to use an electric boiler to get away from fossil fuels. Due to losing power many times during winters, we have a generator. In time I will also install wet solar panels. With so much info out there, I read conflicting info on the manifolds. I was going to make my own but have only thought about this for a few weeks now.
I have attached 2 drawings showing the floor system and also my idea of how I have come up with the way to run the tubing.
Looking for your thoughts, you have some very good credentials.

The images are PDF files from my cad.  My cad is fp3 format.
I can email them.  You can publish if they will help anyone.
removing them from this note.

You clearly appreciate the versatility of hydronic heating and the complexity that can accompany integrating space and domestic hot water heating systems. I have been working on my own for the last three years.

Your challenging questions are intriguing, but too much for this venue. Please forward drawings and scope of work directly to my office We can help with any radiant floor heating design question, but specific engineering takes time...and money.

I would also like to note that using an electric boiler, may or may not, "get you away from fossil fuels" depending on how the electricity you use is generated.
