I too thought that hot water should be hot water... I am using a two outlet water pump on the engine. Both water pump outlets are attached to the heater. My aftermarket intake manifold doesn't have a good source for the water (well at least it hasn't since I built an all steel fuel line for the carb).

I had luke warm air before rerouting the fuel line, which interfered with the intake manifold water source. After plumbing the heater to the second waterpump source things really got cold.
