( 2 internal punps and a completly new way to mix return water with heated water at the exchanger as well as a cross over pipe at water "to" and "from "system pipes) these changes gave me the impression that weil mclain may have had some problems with the original design . Is this true
*** The cross-over pipe is most likely the culprit now. The cross-over pipe should have a valve to adjust the flow through this bypass. There must be enough water flow in the system to heat all the radiators. It is possible the bypass allows too much water to cycle locally without forcing enough water to the radiation. The design is not a problem, but adjustment is in order.
