| I was in your shoes last fall wondering what to do.
Tubes in the floor installed 20 years ago. 40x 42 shop well insulated with 2" insulation under floor slab. 1 oh door facing west 18' X 13'.
I installed a 125,000 BTU boiler (used) and filled it myself. It works good.
About 15 degrees difference between hot and cold loop. Temp of hot water set to 100 derees
