automatic heat source selector

Hi All,

I have a 300 litre 30 tube solar water heater on my roof, which circulates the water through the indirect coil on my 200 litre thermal store.
Do they make a mixer valve that will work out whether the solar water heater water is hot enough and use this directly, or if it isn't quite hot enough, then use some heat from the internal thermal store?

This way I don't need to circulate the water from the solar, as I can use it directly.

Thanks
