A heat transfer system is provided for a road vehicle having a passenger cabin. A primary branch includes a primary pump and a primary power plant. An auxiliary branch includes an auxiliary coolant pump, an auxiliary heat source, and a cabin heat exchanger. A thermostatic multi-way valve directs coolant from a valve inlet to substantially only a first valve outlet when receiving coolant below a first temperature. The valve directs coolant from the valve inlet to substantially only a second valve outlet when receiving coolant above a second temperature. The valve inlet is coupled to receive coolant from either the primary branch or the auxiliary branch. The first valve outlet is configured to return coolant to the same branch as is connected to the valve inlet. The second valve outlet is configured to direct coolant to the other branch to which the valve inlet is not connected.
