Hi all,can any one advise me please?

I have a back boiler with an indirect system.
There is no thermostat on the hot water tank, and the hot water is in my opinion is far to hot. I have small children and this worries me. I have turned down the boiler thermostat to 3 as well.

Is there any way of controlling the water temp better?
can i fit a thermostat to the tank and a 2 way port valve on the pipe from the boiler to the tank to shut off when the thermostat reaches the set temperture? Or will this shut off the radiaters as well.

Thanks Mark
