Vacuum tube water solar heater

We are solar water heaters systems distributers in Irbid City,Jordan.
we currently import our systems from China, however we heard of good products in turkey. our manager xxxxxx will be visiting Turkey this weekend and might stay for few days.
we are interested in receiving a list of specifications and price list of the solar water heater systems from different companies in turkey as we are very much interested in changing our major import from china to Turkey.
