I have a one pump herms system on a single tier when I sparge I use the pump to drain the mash tun into the kettle I run my sparge water from the faucet through the herms coil and into the mash tun. The sparge water picks up some heat from the coil but is far less than 170 degrees. I have no problem with efficiency around 86%. Are there any ill effects of fly sparging with cold water other than low efficiency?
