It’s not clear from your photo how you plumbed this valve, but I have a concern...

The flow through the heating loop cools the engine’s air intake manifold and the EGR valve.
That flow MUST be maintained or you risk the EGR and manifold overheating.

The heater core can be bypassed by diverting the flow back to the block, but stopping the flow puts the intake manifold, EGR, and the boost heater at risk.
