I admire the choice you made to rebuild the entire system as it’s not an easy one. Just to see the previous equipment rendered useless for you is heartbreak enough. Currently…it looks spectacular and the anti-freeze for the fluid lines is perfect. Glad you’re happy with that now and will always enjoy it. That every penny part is the tough one but worth it !!The building is 2400 sq ft, but I have 18' sidewalls, so its a big room to heat. They ended up doing a complete remove/replace. Unfortunately, the pumps with the original system were to small, the manifold piping was too small, but the manifolds were correct.... was just a mismatch cob job, so I just had them start fresh. They did end up giving me a 3k break in the overall price tag due to the fact it was all "their" stuff, and was easier for them to just put all new together than taking apart, and piecing in. I couldnt be happier with the end result!!!
