So guys and gals I want to suppliment my downstairs heating with radiant flooring. I have an oversized HW boiler that is begging for more work. I would like to add the flooring into the existing BB heating system. I have drawn up a plan on how I would achieve this and would like some feedback and advice. Thanks!
