Thanks! Yes, its pretty close to 42 kW, when factoring in both sites (the ones heating my house, and the warehouse).

Electrician is currently installing a new 400 amp subpanel and have a new AC unit arriving today. Additionally, I'm brainstorming on a cooling solution that would enclose the front of the racks in order to exhaust the hot air better, and thereby cool the space more efficiently. Mining is slowing down on profitability quite a bit, but that also means cheap graphic cards coming. I have some orders for ASICs to attempt to stay in the arms race for 6-12 months, we'll see if it pans out. 300 mh/s is the new 100 mh/s. Only advantage I have is a paid off farm and cheap power.
