Tempering Hot Water

I have a 12 gallon Raritan hot water heater with a built in heat exchanger.

The water gets real hot by engine heating--basically a good thing because adding cold water makes the 12 gallons go further. Except some people don't know how to handle it and I would like to install a thermostatic mixing valve near the heater to avoid scalding someone. Any one done this? Looking at a valve on Ebay and the label says @45psi there is a 3.1gpm loss--can't handle that. Any valves that would work?
