It's hard to say how much warmer my truck would warm up with the bypass, as I've never really tested it. I installed my heater core bypass to make my A/C put out colder air.
For some engines, one can get away with using a two-way valve. However, that presumes a good understanding of one's engine internals. For instance, on my truck's engine, there's already an internal bypass between the heater supply port and the heater return port.
