It only took 2 hours and 45 minutes to get up to temp. Since its 70 here were just doing hotwater so I set it to 165 for now. She puked a little water but I would imagine that's just expansion? I am impressed so far and I cant wait to get going with heat this winter. I took a few pics of the entire install and will have them up in a couple of days. I gotta thank alot of people on here for the help as it would have been tough without the help of the folks on here...:biggrinbounce2:
