Modelling laminar and turbulent flow with heat transfer

Greetings. I am quite new to COMSOL and currently working on a project that simulates a hot water tank, where the hot water is fed into the tank in coils and heats up the cold water inside. In this model, the flow in pipe is turbulent, while the free convection in the tank is laminar.
I am on a class kit and unfortunatly do not have the nonisothermal pipe flow module. Instead I have separate turbulent and laminar module, and and Heat Transfer in Fluids module. How should I set up the coupling properly to solve them together? When I try to couple both of the fluids to the same heat transfer, the solver would give a "undefinedcomp1.u"error, but if I make seperate heat transfer nodes and couple the fluid regions separately in 2 multiphysics-"spf1-ht1" and "spf2-ht2", then the system would just solve 2 components seperately and not communicate with one another.
Thank you for any advice and suggestion.
