This is a 10 ton hydronic unit in a new rambler. It has 2- 4 car garages one above the other on spancrete both have infloor heat and the basement has infloor heat. The main level is heated by forced air through a water coil with infloor in the master bathroom. It has 10- 800' slinky loops, sorry, I can't remember what I did with the pictures for that. The copper piping is all propress.
