I am very interested in how you approach this phase of your re-model.

As I recall, you already have fossil -fueled hydronic heating in part of your house.

And your solar panel rack and heat storage tank, both seem aimed at solar space heating... and may likely have lower temperature heat available to you.

I have experimented with Watts Radiant RadiantWorks and have found it very interesting and useful, especially when doing some 'what-if' trial runs. It has helped me understand how varying certain parameters can affect the system performance.

As for myself, I am beginning to favor the use of 3/8" PEX, spaced much closer than usual (3" or 4"), using a multi-tube spiral arrangement, as illustrated below.

...I am also favoring aluminum spreader plates like Gary's floor, topping the plates with 1/4" Hardibacker and finishing the floor with Marmoleum, which has very low R-value.

Best of luck with your project.

I'm not an HVAC technician. In fact, I'm barely even a hacker...
