Good News! EKO 60 is online & functioning. It's below freezing outside & I've been fighting leaks all day BEFORE heating things up. Got them all knocked down, and so far I only have a few minor issues. My circ pumps are moving water, but things aren't heating up much. Two of my alphas are telling me they aren't moving any water. I've bleed as much air out as possible. The Controller is a mystery.... I know...I've got to read the fine tuning thread. Right now it's reading 199r. The boiler was firing fine up till then. As my system gets heating up, it's still not pulling hot water through and after some leaks I know I have to add some more make-up water....perhaps after I fix some leaks. My storage is at 44F. I'm hoping to see some rise in the tank temp soon....at least to give me some confidence that the system is working...... any advice is MORE than welcome.
