I have a modbus device (heating controller) that periodically pushes out new data to a Modbus TCP Server -- I set it up to connect to the node-red-contrib-modbus Server and that basically works fine. Now I would like to act upon data received by the node-red tcp-modbus server, By I can't seem to get it to do anything every time a new value is written.

I don't want to poll the server -- I want it to react immediately a new holding register value is written by the external modbus device.

Is there a way to get the server node to start pushing out msgs/flows upon every WRITE?

I would say you could do this with the Flex Server.
