Excellent idea if you can have the right setup.
The most common type will recover 30 to50% of the heat from a shower
because it has no tank and the incoming water must flow in at the same
time the outgoing water flows out. That's good for showers provide you
have about 1 meter of vertical space below the shower drain but not
for the bath tub or cloth washer.
You can install a pump if you don't have the space .
An insolated tank to store the heat of the water going out will
recover part of the heat going out of all the water exiting but if you
value your time, forget it.
Google heat recovery shower for plenty of information.

The one I heard about first a few years ago was http://gfxtechnology.com/ .
Other sites are easy to find with a simple Google search for grey water heat
recovery.
