I need some help! Please!

For the past few years I have been brewing beer at home. About 6 months ago I decided to upgrade my brewery with electric heating elements. I designed the system to be supplied with standard US 220v power, which is really two 110v lines, a neutral, and a ground. However, as I was almost done with the build I received orders to move to Germany. I live on a military installation and have both European 220v and 110v lines in the breaker box. After examining the breaker box trying to determine what lines I was going to use I realized it looks very different from a US breaker box. I have also looked into getting a transformer, but that still doesn't address my problem. As mentioned before, it is designed to be supplied with two 110v lines that are 180 degrees out of phase. Most of the components run off of just one of those lines. However, in order to power the heating elements I need both hot wires. The total power consumption could be up to 6,000 watts (assuming I only run one of the heating elements at a time, which I can do). What do I need to do to supply power to my brewery?

I have attached a wiring diagram that is very similar to my control panel.

I have also attached a picture of what my breaker box looks like.

Here is a couple picture of what the brewery looks like, I case you are curious.

I thought the yanks achieved 240v by using a high delta wild leg. Which is 207v to earth.

They use all kinds of funny arrangements. 240V delta with one phase centre grounded would give you 120-120-208 to earth and 240V between hot-legs.

I suppose I could rewire the control panel and isolate all the 110v components. Then, run a seperate 220v circuit controled by for the heating elements. Would this work? Will the heating elements function normally with one 220v hot and one nuetral instead of two 110v hots?
