For locations that don't freeze very often (or seasonal); I highly recommend it.
The primary improvement i would like to make is to add a recirculating pump on the solar portion only. That way I would have instant solar hot water, and the Bosch wouldn't get a cold charge every time I switch on a faucet. I'm guessing it would be about a wash on energy use due to less heating requirements, but would have enhanced creature comfort.
